Let’s start with the first thing about this camera, and that is it’s a full frame DSLR featuring 24.6 megapixels. When holding this camera, you will immediately notice its weight as the entire body is based on a magnesium alloy frame, with environmental seals.
With an ISO range of 100 up to 6400, a shutter speed of 30 sec down to 1/8000 of a sec, continuous shooting up to 5 frames/second, single or continuous bracketing and exposure compensating of -/+ 3 steps, this is the camera the up and coming professional will be seeking. When you consider the file size (up to 6048 x 4032) they added a second Bionz image processing engine to accommodate the huge data size.
The viewfinder of the A900 is both huge and very bright, and offers a huge amount of creative control as you would expect from a professional camera.
The A900 has two card slots, one for Sony’s proprietary Memory Stick Duo format, and it is possible to select which card your image will be stored.

Pro’s:
* Very well built
* Excellent photo quality
* Body button placement is very good
* Easy to use
* Best image quality obtained in RAW mode
Con’s:
* Lacks auto-dust cleaning on the mirror (need to invest in some kind of third-party sensor cleaning solution to keep the image sensor completely free of unwanted dust)
* The camera lacks a pop-up flash requiring a proprietary flash shoe
* No Live View shooting capability
* In higher ISO settings in JPEG mode with the default noise reduction settings, the images are a little noisy over 800 ISO
* RAW mode uses 36 Mp/image
* There is absolutely no question that it can out-perform almost anything else on the market, outside of the larger studio type cameras. This camera is a high end professional camera without a doubt. DSLR-A900 is one of the highest-resolution digital SLR in the world, and also the first “full-frame” digital camera with an anti-shake function integrated into the body.
