SONY ALPHA DSLR-A900

 Sales of camera SONY ALPHA DSLR-A900 has already begun.In the market of digital SLR cameras has a powerful player on the move to take a place in the top three with a full range of cameras – from inexpensive, entry-level A200 and A900 polnokadrovoy Class High-End;almost completely covered a range of high quality lenses and a great set of accessories.

One of the key benefits of the new camera – 24.6-MP Exmor CMOS sensor with pixel size of 5.94 microns (roughly comparable to the 5.49 micron 12,24-IP matrix A700), which permits more than twice the resolution of the predecessor A700 and more than a similar class models of competitors. Exmor image processing system has built-in matrix “column” A / D, a relatively low noise is achieved by obtaining a digital signal in each cell, as well as the consistent double noise reduction before and after analog-digital conversion.

The next phase – processing Bionz image processors in the two versions specifically for the A900.Processor doubled compared with the A700 for the processing of large data sets with 24.6-MP matrix, the noise reduction is also performed on the stage of working with RAW (RAW NR), in the beginning of image processing.

The model A900 supports high sensitivity up to ISO6400 (in expanded range ISO) with the function of noise. The ultimate goal – a realistic high-quality transmission of colors and shades with the transitions 24.6-MP matrix.The use of two processors at once Bionz, in turn, has resulted in speed shooting up to 5 frames per second at full 24.6-MP resolution, while the buffer device is designed for more than 100 images in the JPEG Fine.
It is a new feature first debuted in the A900 – this is an opportunity to preview the Intelligent Preview to display on the LCD monitor, the results of adjusting the white balance, dynamic range optimizer DRO and exposure, without recording the image.To display the preview images with histograms, just click on the repeater diaphragm, the user can set new values and not “fluff” with the settings when shooting complex compositions.

Many amateur photographer got to appreciate the built-in camera, all the dynamic range optimizer Alpha – Dynamic Range Optimizer (DRO).In cell A900 DRO realized improved algorithm for more accurate analysis and evaluation stage of correction, with a smooth correction of settings that allow for a more complete range of tone transitions, even with very difficult lighting conditions.

The camera used a big 3-inch LCD Xtra Fine LCD with high resolution (921 thousand pixels), familiar to owners A700 – a sharp and contrast even in bright light and outdoors.A wide range of thumbnails for easy selecting the best shots, as well as the possibility of finding a full RGB-histogram and information on camera settings.By clicking Fn display switches to the navigation Quick Navi, that allows you to quickly adjust the settings, no job.

The new camera supports all AF lenses Sony, Minolta and Konica Minolta, but in the case of the APS-C lenses (with an index DT) image is automatically cropped to the APS-C size 12 lm, and the manufacturer does not guarantee the correct working of Multi Metering for optical DT . Please keep in mind.

 Series Info LITHIUM Battery NP-FM500H, now used in all cells Alpha, making up to 880 images (measurement standard CIPA), showing the% remaining charge. Built-in flash in the model A900 is not, so this result can be obtained with high probability.

By analogy with the recent series of cameras, A900 is equipped with HDMI output for viewing images on the screen, HD Ready, and supports the HD PhotoTV to view images in Full HD format compatible TVs BRAVIA. HDMI port also provides the ability to view images with a resolution of HD on any compatible TV.

The key concept, originally built in the development of Sony A900, is to transfer the image closest to what the human eye sees, that is, to achieve maximum transfer of accurate and realistic picture.

CANON EOS 5D Mark II

 This event was looking forward many. The Company Canon has announced the release of a new a full 21.1-megapixel camera EOS 5D Mark II. This is the first model in the series of EOS to support high-definition video format for Full HD.

The first model 5D, released three years ago, has become the most affordable full-mirror camera. And it is still quite self-sufficient and competitive camera.In this regard, the date of announcement 5D Mark II can also be described as involuntary, as its predecessor, and so excellent was sold. This was due to the fact that the number of photo, moved to digital SLR cameras, with the growing every year.And because the segment of the budget includes fullfreymov EOS 5D, Nikon D700 and  Sony A900, to better understand the other developers Canon, Nikon and Sony.

 Around the 5D Mark II reigned serious excitement. This is due primarily to the fact that between the release of a model and available for sale on the markets of different countries took about two months.This razbezhka more fuel the interest of potential buyers who hungry eyes watching videos Vincent Lafore and enjoy photos anboksinga, filmed by Japanese-owned lucky.

5D Mark II – the world’s first digital SLR camera that shoots video in solving FullHD. This attracted to the model, not only photographers, but many video, which painstakingly explore the histogram from the first movie Vincent Lafore. As a result, potential users have come to the conclusion that the camera without any problems roll in poor lighting conditions, professional video cameras, which are considerably more expensive than new items Canon.

Among the main features of the camera should be noted polnokadrovy (24 x 36 mm) type CMOS image sensor resolution of 21.1 MP, DIGIC 4 image processor, and feature video.In the video camera Canon EOS 5D Mark II supports the resolution of 1920 x 1080 and frame rate 30 frames per second. The duration of the video is limited to 4-GB file size, created on the card, which corresponds to about 12 minutes of Full HD video or 24 minutes in the resolution of VGA.Use the format. MOV video compression algorithm for MPEG-4 (audio – PCM).

Other advantages Canon EOS 5D Mark II includes an expanded range of sensitivity, defined boundaries 50-25600 ISO, and 15-point Autofocus with a choice of nine points (the remaining five spots – the subsidiary).Three central points provide additional opportunities to lighter lens f / 2,8. Converting an analog signal into a digital image sensor submission is 14-bit converter. The unit is equipped with a 3-inch screen with the function of Live View.In the serial shooting mode the camera is able to do 3.9 fps (if you use this card UDMA CF, in RAW format, you can make 14 shots in succession). Declared shutter life is 150,000 alarms.

The camera can confidently recommend to all – sorry about the choice will not have to explicitly. The model is a clear leader of all fotorynka and perhaps one of the best full-SLR cameras today.

Given the value of 5D Mark II, Canon once again the company to issue a call out competitors, and even slapping lightly hurt producers sredneformatnoy digital photography.21 megapixels makes this camera the perfect solution for studio shooting, but lower than those of competitors in the face of Sony A900 and Nikon D700, the frequency of serial imaging is sufficient for everyday tasks.
