Until now, the concept of smart contact lenses from Google, which are able to measure the blood sugar level was just a concept. Now the corporation has received a patent for such a lens so that the system has become much realer than ever before. It is worth recalling that the lenses are not only measure blood sugar, but also transmits the measurement result to the application on a mobile device, because of the presence of a miniature wireless communication module.

Lenses of this type can be a real salvation for many diabetics, especially with the complicated form of the disease. For these patients, it is vital to know the time the blood sugar level. In order to become a real lens, in July 2014 the company entered into an agreement with Novartis, according to which both partners will collaborate on the project.

As a representative of Google itself acted division, Google X. This division is working on the study and implementation of projects that are at the cutting edge of science, including Google Glass and robotic vehicles. Also in the Google X working on a portable handheld device capable of serving as a detector of cancer.

This detector, according to the plan, is available together with special magnetic bracelets, which acts as a monitoring and control nanobots that run in the blood to detect possible cancer markers.

Now another project the corporation has become almost real. It remains only to wait for the smart lenses on the market.

The company is a top NEOLINE DVR Wide S53 with a wide viewing angle of 170 degrees, Super HD resolution and the ability to shoot Full HD video at 60 frames per second. Thanks to the sophisticated technical solutions, NEOLINE Wide S53 provides a good quality recording day and night, in all weather and lighting conditions. New shoots video at resolutions Super HD and Wide Super HD (2560 p): on the record will be visible all the fine details, including road signs, markings and numbers of cars at a distance from the DVR. As a Full HD shooting will be conducted at a speed of 60 frames per second! This figure is twice the standard and provides an absolutely clear image at a fixed fast moving objects – shooting at a speed used in the manufacture of high-budget movies.

With a wide viewing angle of 170 degrees picture of a traffic accident is the most complete, because the shot will get all lanes, including the opposite direction, as well as the sidewalk. But despite the wide-angle lens design, the image will not be distorted, and the objects in the picture will retain the right proportions. An important function of NEOLINE Wide S53 is support for HDR: it provides high image contrast in difficult conditions – in the dark, with a sharp change in illumination and glare of headlights of oncoming cars.

NEOLINE Wide S53 is equipped with a modern processor Ambarella A7L70 and the lens of six glass lenses. The device is cyclic recording on MicroSD memory card up to 64 GB, and the impact or sudden braking converts the current video in indelible buffer. View footage can be built on a 2.7-inch display or on a large TV screen by connecting the DVR via HDMI. If desired, the user can “fix” the device to the car and set the settings stamp staterooms. Also on the device provides emergency recording button: you can use it to take pictures in high resolution, without interrupting video recording.

New support JavaScript Time-Laps. In this mode, the device is shooting with reduced frame rate to save space on the memory card and “shrink” the size of video files. When you activate Smart DVR mode automatically switches to Time-Laps, if for 3 minutes near the car will not be recorded movement. This function can be used, and to shoot creative videos in the “fast-track recording.”

NEOLINE Wide S53 easily mounted on the windshield via suction cup mount staff. It implemented the ability to charge via the miniUSB: as soon as the device is fixed in the holder, it automatically starts to receive power.

“Our top-end DVR NEOLINE Wide S53 we are ready to offer users more than just a device with the best quality video. So, the owner of a new NEOLINE Wide S53 can record a day trip, compressed in 2 minutes, thanks to the Time-Laps. Or at 60 frames per second to capture stunning video, comparable in quality to high budget movie. I’m sure these nice features like device users NEOLINE”, – commented on the release of news Helen Doronin, head of marketing NEOLINE.

NEOLINE Wide S53 will be available in March 2015.

Low vision – a fairly common problem, and solve it is not so simple. Draft Swiss scientists to create a lens with a controlled increase can help a wide range of people with poor eyesight. The thickness of the lens is only 1.55 mm, but the zoom ratio is 2.8 – is considerably higher than in the vast majority of modern contact lens.

Lenses partly consist of plastic, aluminum, and polarization films. Metal is used to create micromirrors that reflect the light, at the same time increase the image. Scientists are also provided, and the presence of special oxygen channels.

Lenses of this type of work as a single system with special glasses. Management made a wink (on blinking glasses do not respond). If the left eye wink, increased activated if the right – off. So far, the project is still under development, but there are working prototypes, which are now being tested by scientists.

Olympus has emerged at the end of the First World War, and initially specialized in the manufacture of thermometers and microscopes. After accumulating enough capital firm redeveloped and began producing high-tech scientific and medical devices. In the 1930s of the last century began to gain enormous popularity photograph, and the bosses of the company set a goal to enter the market with a camera of its own design. It was published in 1936, and since then, Olympus is firmly entrenched among the world’s manufacturers of photographic equipment. Read more about the history of the corporation you can read in the category RetroSearch.

Now, Olympus is primarily known for its mirrorless cameras format Micro 4/3, which was announced in conjunction with Panasonic in 2008, and lenses that are produced under this format.

Consider marking the latest:

ZD (Zuiko Digital) – marking supplies glass to the system 4.3.

mZD (M.Zuiko Digital) – designation accessories Lens System Micro 4/3.

ED (Extra low Dispersion) – This character string indicates that the optical design of the lens using the lens with extra-low dispersion. They are used to ensure maximum sharpness and color accuracy even in the most open apertures, minimizing chromatic aberration. ED-lenses also resistant to mechanical damage, that with great success allows them to open the lens elements (front and rear).

EZ (Electric Zoom) – a designation that indicates that the zoom lens is equipped with a motor drive.

75mm, 50-200mm – the focal length of the lens. In zoom lenses first specified minimum, then the maximum focal length.

1: 1.8, 1: 3.5-5.6 – the maximum possible value of the lens aperture. In zoom lenses indicated two values for minimum and maximum focal lengths.

SWD (Super Wave Drive) – SWM focusing designation that provides Hustler and quiet autofocus.

Pro – the so-called lens Olympus, which are dust- and waterproof.

Top Pro – the professional designation of the series, which has a constant value regardless of the aperture ratio of the focal length. Naturally, the glasses in this series are not afraid of dust and water. Inscriptions on the lens barrel can not be, but you do not confuse it with any other – it will give a platinum ring.

Standard – amateur photographic series. Select the windows of this class can be due to the blue ring, which are marked.

MSC (Movies and Stills Compatible) – literally, this combination translates as “compatible with videos and photos.” Abbreviation indicates that the photo mode autofocus quickly touches an object, and in the video mode is ensured by its smooth and quiet operation. These glasses have in their arsenal a separate mechanism, which consists of:

• worm gear;
• high-speed motor, which has a high precision movement and fixation;
• guide shafts, tolerances are measured in microns;
• focusing group weight loss, which provides high speed and accuracy of focus.

Macro – standard notation fitness lens for close-up photography.

On this for now. As usual, corrections and additions are welcome.

It is believed that a picture taken with the lens focal length is approximately equal to the diagonal of the frame, will look most natural for human perception. Such a lens is called “normal.” It is necessary to clarify that in fact the normal focal length for a film / matrix size 24×36 mm is 43 mm. But this does not prevent the lens with a focal length of 50 mm was to become mandatory, according to most photographers, photographic element in the set. It is worth mentioning about the “equivalent focal length” lens for full frame cameras with no matrix (crop-camera): Fekv = F * Crop factor. In this case, since we continue to go about the system Canon EOS, then Fekv = F * 1.6 (50 * 1.6 = 80 mm).

I am sure that all enjoying photographic equipment Canon sign one of the most popular lenses of this manufacturer – Canon EF 50mm f / 1.8 II. It was he who most often acquired immediately after purchase “reflex”. Its low price and high aperture ratio obtained for this price, left no doubt the “rookie” in the ranks under the banner of Canon.

Manufacturer from China YongNuo, well known for his on-camera flashes, on-camera LED (LED) lamps, sinhonizatorami flares and various accessories to them, rapidly expanding range of products, entering the ranks of manufacturers of optical devices. It all started recently with the release of teleconverters under the name «YongNuo». Their quality and ease of use while I can not say. The next step was the release of the lens. They became YN EF 50mm f / 1.8, looks very similar to the above-mentioned Canon EF 50mm f / 1.8 II. In fairness, it should be noted that until recently, the model flares from YongNuo, well, very reminiscent of the flash from Canon.

Lens YN EF50mm f / 1.8 at the end of 2014 is not officially sold in our country, so it was purchased through the service Ebay in China (at the time of purchase, in December 2014, its price was 3300 rubles.). And therefore, to evaluate the difference in cost can only be compared YN EF 50mm f / 1.8, bought there, with Canon EF 50mm f / 1.8 II, sold here. YN EF 50mm f / 1.8 was cheaper than about 700 rubles. It is not critical, but it’s nice, especially as a percentage of the purchase price.

His body and mount made of plastic. In size lens YN little more Canon: 73×55 mm and 68.6h40.6 mm respectively. The diameter of the filter for both is 52 mm.

Anti-reflective coating on the lenses present, what they say reflect purple and green colors.

Aperture blades in glass from YongNuo two more compared to said lens from Canon. Through this lens bokeh looks advantageous form of light sources in the image closer to the circle, because the aperture is in the form of a heptagon, not the pentagon, like lens Canon (because of these pentagons on a photo taken with a Canon EF 50mm f / 1.8 II, its many and criticized).

Needless to say, that we are an ultrasonic auto-focus drive is not. Motor in the lens, making noise, reminiscent of the crunch, it is smartly suggests sharpness. Yes, this noise could spoil the mood to anyone who takes the camera video, but not particularly worried about when taking pictures. But the quality of the AF was an unpleasant surprise. When used with not a full frame camera Canon 40D, Canon 450D noticeable error autofocus. First, even thought it was a stable front focus (focus falls on an area which is closer to the camera than the one on which the focus point is shown in the viewfinder or on the camera). But by taking some statistical sampling is easy to see that there are pictures with sharp focus and autofocus misses can be as one, and the other way, but with a predominance of the effect of the front focus. And then immediately remembered the experience of using the lens Canon EF 50mm f / 1.8 II, which once I had. In this model, but will not let me lie fellow photo, cases with precision AF never went well. It is believed that the cause of the error in the operation of the system autofocus lens design features are associated with the direction of the maximum decrease in its value. For this reason, the developer does not have potential service program alignment. Everything to simplify and reduce the cost. True, I heard that someone was lucky, and the lens is always exactly focused. I think this is a real stroke of luck coincidence features autofocus those elements that are in the camera, with autofocus drive features present in the lens. But it’s all about the other lens, which is so similar to the subject, and to give them full and detailed comparison is not possible.

Returning to YN 50mm f / 1.8. AF error that occur when using a lens with no full frame cameras Canon 40D, Canon 450D, become completely indecent, when you install the lens on a full-length machine Canon 5D Mark III. This is understandable, because the value of the depth of field (DOF) is inversely proportional to the size of the photosensitive member unit (matrix or film). In this case, the larger diagonal of the matrix, the smaller the depth of field. That’s why all the more obvious inaccuracies focus.

Another annoyance was the failure of the lens to focus the use of cameras Canon 40D and Canon 5D Mark III mode LiveView. And, if in respect of 40D, as the first SLR camera Canon, in which the opportunity to focus mode LiveView, with all the features of the “first pancake” in this area could be something similar to assume that when working with “dimes” nothing to expect and it never occurred. Drive the lens works, trying to lock on sharpness, but after a round-trip stops without completing the job.

In any case, to assess the quality of the image produced by this lens, translate two-position switch on the lens to manual focus (AF – MF). Focusing ring YN EF 50mm f / 1.8, as well as ring Canon EF 50mm f / 1.8, as well as the vast majority of modern ring autofocus lenses for digital cameras, has a small stroke that makes it extremely difficult achieving focus manually.

Below are pictures taken with the camera: Canon 450D, Canon 40D, Canon 5D Mark III, using lenses YongNuo YN EF 50mm f / 1.8 and Pentacon 50mm f / 1.8 (with adapter M42 – EOS EF).

The difference in the viewing angles due to the size differences “working segments” cameras Canon EOS (44 mm) and camera type Practika screw mount lenses M42, which was created this lens (44,7 mm).

To summarize, it must be admitted that, despite some structural differences, which can be assessed without disassembling the lens (a larger number of aperture blades, the presence of the four screw mounts on the end of the lens barrel side mount) compared with the same lens from Canon, name objects YongNuo YN EF 50mm f / 1.8 optics innovation in the ranks does not work. And it’s not so much in the resemblance, but in similarity problematic issues in their work. The lens of a series of the most inexpensive, for which he can forgive a lot, but if in the same sentence to express my impression of the work with him, it would be “not credible.” I would not have chosen it for sequential shooting celebration or an important event, where it is important not to miss the moment, which need the speed and accuracy of focus. For a leisurely portrait shooting, when you can adjust the focus manually, the subject is also not the best choice, because, as mentioned earlier, manual focus constructively organized uncomfortable.

Unfortunately, in my opinion, at the moment the workmanship and on-camera flash units, the LED light at YongNuo higher than the quality of the lenses. But production in China is developing comprehensively and with incredible speed. 10 years ago I had not heard of the company YongNuo. And there is no doubt that in the near future there will be new objectives of this manufacturer. There has been the announcement of the imminent YongNuo YN EF 50mm f / 1.4, which, judging from the photos on the network, again strangely similar to the Canon EF 50mm f / 1.4. And I want to believe that the manufacturer will be able to raise the level of manufactured goods and save on auto-focus elements in the least.

In the run-up to overcome the 100 millionth milestone sales of lenses in the history of Canon, the company decided to permanently reduce the cost of a number of lenses of the current line. Discount ranges from $ 40 to an impressive $ 1,000 for the most expensive items.

Undisputed leader in subtraction value became lens Canon EF 24-70mm f / 4L IS USM. Its price dropped from $ 1500 to $ 1000, which is the third. Just on pricing with this glass photographers (and even videography) complained about the most. Now it’s relatively affordable classy regular zoom for full-frame cameras with optical image stabilization. Videographer in general may find it an ideal standard glass.

Discounted by as much as $ 1,000 boast super-telephoto lenses Canon EF 400mm f / 2.8L IS ll USM, EF 500mm f / 4L IS ll USM and EF 600mm f / 4L IS ll USM. Their cost is now $ 10,500, $ 9,500 and $ 12,000, respectively.

Whale lenses occupy, as a rule, a very interesting place in any area of ​​the shooting, both video and photos. That kit lens supplied with many cameras, are those first optical element through which newcomers learn about the world. For other whale becomes thus an indispensable element that “does not feel sorry for” and that they put on the camera while traveling. But nekotoroh our materials, for example, in this or that, we discussed that the kit lens, in spite of its price or positioning is not always exhibit poor image quality.

And once again we will try to convince our readers that the kit lens – not bad. On an example of Nikon 1 Nikkor 10-30mm F3.5-5.6 VR ED IF Aspherical PD-Zoom.

Externally, this lens is more like a pancake. Small size, well-built, made ​​out of metal with small patches of plastic. Of the controls – only one wheel, covered with plastic pupyrchatuyu – for smaller hands slip. Ring is responsible for zooming.

But such a small size is achieved by the fact that when the camera off, the lens is in the folded position. When the forward leaves the shank, which is equal to the length of another “pancakes.”

Metallic bayonet, which is very good, especially for fans of the aggressive use of gadgets.

Just want to say that the zoom does not happen as smoothly as we would like. At the same Nikon 1 J4 Zoom in / out does not occur evenly and smoothly, but rather choppy. While noting the efforts of the non-uniform requirements – sometimes to go through all focal lengths from wide to long end had to make cranking little if not 360 degrees, and sometimes – just a quarter turn.

Regarding the ability to quickly zoom in – there is also not so smooth – Electronic zoom demonstrates a solid by the standards of photographers delay, due to which you can easily miss an important point. My opinion – mechanical zoom in the previous version was much better. By the way, is a problem not only for us – the English-language Internet is teeming with such statements.

AF – quite good and sufficient light touches objects correctly and well. False passages begin to occur only in low light conditions, but it is not particularly critical.

Sistama VR works very well – you can shoot handheld at shutter speeds three stops longer than with lenses without VR.

The optical characteristics of the lens slightly improved compared to its predecessor.

Vignetting is at an acceptable level and manifests itself only during shooting scenes at wide angle with a maximum open aperture. But whale lens is to be expected.

Distortion also manifest themselves only at the maximum short focal distance, but worth slightly zazumirovatsya and the problem disappears by itself. However, the problem, as well as the issue of vignetting can be easily solved by including intracameral defect correction or corrected in the same Lightroom. And you can use their creative ideas, turning disadvantages into advantages.

Resolution also demonstrates not much higher than the first version of this whale assessment. The center of the frame, anything below F8 – excellent, from F8 to F11 – very good. Edge of the frame – “Very good” and “good” on the respective apertures. But after covering more than F11 count on crystal-clear and sharp image is not necessary.

With chromatic aberration things are much better. Color pixels are almost invisible to the naked eye on the appropriate magnifications. However, if you’re even going to get prints A3 and above, the question defective decides editor.

Summary – Nikon 1 Nikkor 10-30mm

This lens costs about $ 300, and perhaps as a separate purchase, I would not recommend it – it is not very much and it is light, electronic zooming debugged is not on the “5 +”, and the focal lengths still want more after some time with cam. But here’s a bonus to the same Nikon 1 J4 or Nikon 1 V3 – pretty good, considering the fact that the lens “is not sorry for all occasions” just have to be everyone who is engaged in a photo or video.

Probably just lazy people never heard of the legendary instrument Henri Cartier-Bresson – Leica (you can read her story here).

Due to the enormous popularity of cameras in the first place, and accurate manual assembly each instance, thorough work on all nodes of the mechanism, reliability and quality. Some even believe that the optics of Leica – the best in the world. But I think here it is more that the rangefinder camera – it is, after all, a different world, a different philosophy, a different vision.

Initially producing copies Film, Leica has gradually shifted to digital FullFrame, type M9, medium format S-Series, as well as expanded its line of more affordable V-Lux, D-Lux, X and C. And now the family added a new bezzerkalkoy – Leica T.

The form factor is typical of most modern mirrorless cameras. Body machined from a single piece of aluminum – now it seems the trend. I think that the weight and tactile feel will be more than enjoyable. Yes, and look clearly appreciated by lovers of minimalism. Not for nothing above it worked designers AUDI.

Controls a bit. Top – a few buttons and drums control, rear – fully touch screen immovable.

He then 3.7 inches, with a resolution of HD, made by technology TFT. Producers promise that the management of all functions of the device is incredibly simple and logical thanks to redesigned menu. So you can not worry not only on account of the on / off some settings, but about otsmotren material. The display will also be well read in bright sunlight – at least, the press release promises that it will be so.

But the Leica offers everyone to purchase an external viewfinder. With 0.71 x magnification, 100% frame coverage and FullHD-resolution. In general, the eyes do not tear.

Inside – 16 MP APS-C matrix. A smoothing filter before it is naturally not. I think that this head will be enough to get great shots in all conditions. Sensitivity range – from 125 to 12,500 ISO.

Autofocus contrast type. Available to the user a huge variety of modes: Single AF or tracking, multi-zone, aiming point or aiming to identify the person – all, as in all.

Of course, do not forget about the manufacturer and the trend of the season – you can now connect your iOS-device (and only iOS) to the camera, Wi-Fi and a fumble photos or use your mobile device as a remote control.

Together with the Leica introduced its four new T-lens. Two of them, The Vario-Elmar-T 18-56mm F3.5-5.6 ASPH. and Summicron-T 3mm F2 ASPH. – Already been submitted and are available for purchase.

Promise even two glasses – 11-23mm F3.5-4.5 and 55-135mm F3.5-4.5. As for me, too dark, and could be lighter. For owners of the M-line optics is a special adapter.

Naturally, for those wishing to have a huge number of various accessories, cases, straps, handbags, but be prepared for the fact that all this will cost a lot.

Price per carcass – 1850 dollars for The Vario-Elmar-T 18-56mm F3.5-5.6 ASPH. – $ 1,750 for Summicron-T 3mm F2 ASPH. – 1950 dollars, and the viewfinder – $ 600.

It turns out that this camera purely premium class, and entertainment for the soul, but not for serious work. At least, so I can see it.

And any thoughts about the new Leica T-system do you have?
