List of what Sony have VS Nikon (mostly) not :-)

I wouldn't buy one of these things.

Every camera have his "pros" VS "cons", but here, a short list of what Sony (A99 and/or A77 and some others) have and Nikon DSLR supposed not... (So, everybody can contribute if some mistake... ahahah)
— thinner design of the sensor, what means making the light-sensitive "wells" less deep;
- -> what mean the sensor being less sensitive to angles of incidence which (among other things) translate to better utilization of really fast lenses - like f2 and beyond (btw);
- -> what mean light sensitive part of each photo site is bigger (Photodiode expansion) ;
- -> what mean more light gathering area per pixel (for the same light available), and thus for the entire sensor.

— EVF (with all adjustments);

- -> what mean fill all the field of view,
- -> what mean accurate manual focusing, because the EVF allows you to magnify an area to clearly see when the subject snaps into sharp focus (focus picking). EVF screens also brighten automatically, making it easier to see a scene – especially the DOF –  in low-light situations, or preview at smaller apertures.
- -> what show much more information than an OVF. Besides exposure numbers, an EVF can show a live histogram map of the dark-to-light tones in the image. It can show a live preview of white balance settings and simulate shutter speed, among many things (in-camera real time preview, with all parameters of settings available on screen and can be updated in real time before shooting);
- -> what mean unequalled control in conditions of near-darkness (because of the EVF);
- -> what mean it’s not just what you see through the viewfinder that’s different. It's also a new way to take shots, and make photography.
— LCD brightness boost for sunny days;
— in-body image stabilization (Nikon have only some stabilized lenses, when all Alpha mount take benefits of this in-camera steady-shots);
— legendary embedded colorimetry and other precision measurements provided by the Minolta heritage;
— WB in Kelvin degrees (only some Nikon's have);
— no "vintage" design and interface (philosophy of an "easy to use" interface dedicated for a better creative photography);
— efficient in-camera wireless flash system in standard (option for Nikon)
— fixed-mirror design SLT, for in-camera low vibration and silent mecanism;
— in-camera pro XLR inerface connectors for such video/audio pro applications (option through new hot shoe) + in-camera adjustable audio record levels for video;
— in-camera stereo microphone;
— great in-camera .jpeg colour balance on every cameras (no yellowish nor redish);

— unrivalled dual AF system (AF-D) , what maintains tracking focus in critical situations;
- -> what mean  the AF-D focus mode utilizing the much written about 102 extra PD focus points on the sensor. Essentially there are two almost rectangular groups of AF sensors on each side of the central AF point.
- -> what mean it should be much better at tracking moving subjects by giving the camera an almost 3D sense of the subject ("Depth mapping") .
- -> because Sony is using on sensor PDAF to assist the traditional AF sensors
— "AF Range control" button – The idea of limiting how much distance up to and beyond a subject the AF is supposed to go for should have a very real potential of reducing hunting and sudden drastic misfocusing.
- -> what mean you can manually selecting foreground and background distance to which the AF system will not respond;
- -> what mean no more lens hunting back/forth from MFD to infinity!
- -> what provide Full-time Continuous AF Movie mode, allowing smooth, non-stop tracking of moving subjects.
— in-camera smile/face recognition;
- -> what mean this basically is a "content aware" focusing system, a bit related to face detection and similar, but faster and more geard towards fast tracking of erratically moving subjects;
— new area-specific noise reduction (NR) algorithm (for low AND high ISO);
- -> what can vary the amount of NR depending on the content (Area specific noise reduction!) is supposed to analyze image content and vary the amount of NR depending on the content. Basically more NR in smooth areas (like a sky) and less in areas with lots of detail, so not to smudge legitimate detail;

— first full-frame DSLR to offer Full HD 60p/24p progressive video recording to meet AVCHD™ Version 2.0 specifications;
— Have a new silent, programmable multi-control rotary dial;
- -> what mean you can change video/photos settings on the fly (including exposure compensation, ISO sensitivity, shutter speed, aperture and much more);

— one handed twist of a locked knob;
— Can be operated via remote PC connection;
— Have two dedicated memory slots (what you can enslave to a dedicated application) what provide an uninterrupted ‘dual-card’ recording using both of the camera’s media slots.
— Use a Sony standard battery pack (NP-FM500H mostly the same as other D-SLR(T) of this brand);
- -> can embedding three battery pack at the same time (with the grip);
And last but not least: Carl Zeiss zoom's  lenses and some prime's (Nikon can use only some);

So, globally, Sony have not the same approach than his rivals. Up to what photographer you are and your needs (of course)! If — as a pro — you are more creative than a sort of technician geek mutant ( ) I strongly recommand Alpha mount!

Kind Regards,
