Sony Alpha DSLR - A900 Trying To Compete With The Giant Image Of The Industry

Sony A900 digital SLR is one of the most anticipated in recent memory list. The company first showed an early version of the flagship show of the upcoming Photo Marketing Association trade in the spring of 2007, and next year to show some of the details revealed on Sony's image sensor and the stabilization mechanism should use it. Alpha A900 full-frame 35 mm size CCD image sensor, Sony has joined the club, enough. So far, only four companies have provided full-frame digital SLR cameras. These two - Contax and Kodak - as the market for digital SLR cameras are completely cut off.

Sony went shopping in a head-to-head with the two giants of the photographic industry - Canon and Nikon. Each participant has two full-frame digital SLR - a model of mid-range to about $ 3000 MSRP, and triple a professional model for twice as much. Sony seems to be quite upset the status quo seems to price its flagship product, at about the same way as its competitors mid-range models, but with a specification that is between competing models and mid-range Pro - and in some cases, such as sensor resolution, actually introduced the box. Sony Alpha A900 has a huge 24.6-megapixel sensor resolution full frame Exmor CMOS image - the highest resolution sensor 35mm SLR yet known. To manage all data from high-resolution image sensor generates, uses Sony Alpha DSLR-A900 dual BIONZ image processor, and permission to shoot five frames per second up to 11 JPEG or 13 RAW images.

The sensor is mounted on a movable plate image stabilization in the chamber, SteadyShot INSIDE marking authorized amounts. It's another world first for a DSLR full-frame, and no small feat when you consider that the sensor shift mechanism, consider the extra weight of a full frame sensor. Various DSLR seen to date that the image stabilization features are CCD sensors smaller crop 1.6x. Sony has met the challenge by developing a new sensor mechanism for change more powerful, and the rate of the Alpha DSLR-A900 very good for an improvement of 2.5 to 4 stops.

The Sony DSLR-A900 body building consists of five magnesium alloy and includes major sections to reduce the seal against moisture penetration between body parts, as well as buttons and different buttons. The Sony A900 has a Sony Alpha mount, which also supports Konica Minolta and glass. A big pentaprism is above the mountain, both dictate the rules of the camera body aesthetics of the visual arts and an expansion of the very large and bright viewfinder 0.74 x TTL. The back features a large 3 inch LCD with 921,600 dots, which is VGA (640 x 480) with three pixels R, G and B dots per pixel. To the test images, as well as menus and status display, the Sony Alpha DSLR-A900 does not offer live view capability. There is a small built-in LCD display panel of the state, the number of views and the remaining life of the battery, and exposure variables

The Sony Alpha A900 offers an ISO sensitivity of 200 corresponds to 3200, but can be expanded to ISO 100 to 6400. Shutter speeds range from 30 to 1 / 8000 seconds and a bulb setting and the x sync is 1 / 250 seconds (or 1 / 200 seconds when SteadyShot is enabled). The dosage is made by a sensor 40 segment honeycomb, and you can choose between modes weighted or spot metering. The development is reached, courtesy of organizing aa nine-point phase of the autofocus sensor twice cross the center 2.8, and there are ten additional points AF light areas near the main objective. There is no inflammation in the Sony A900 built with the design, rather than offering a shoe and PC sync terminal for external flash units, flash and lighting.

Sony Alpha DSLR-A900 includes two slots for flash cards, and then the images from CompactFlash Type I or II cards (including Microdrives) or Memory Stick Duo. Sony A900 gets its strength to the NP-FM500H InfoLITHIUM battery is rated for approximately 880 shots per charge on CIPA standard testing. The connections are both USB 2.0 Hi-Speed ​​USB on your computer and standard definition video. The standard-def, is a PAL / NTSC selectable composite video output terminal, while the high-definition HDMI interface is reached.
