Sony A99

This a comment for this page on the website
What is the source to mention that in A99, 50 to 60% of light is spent to drive the dual AF system ?

If so, why doesn't it affect the color depth & dynmanic range (both scores same as D600) ? after the tranmission of light is reduced by half ?

To avoid embarrassing yourself, at least try to get your facts right? Where did you find the ridiculous 50-60% figure?

The light loss is a rather negligible 1/3 *stop* loss of light only, a difference most people can't even tell with their naked eyes.

However, camera shake and mirror vibration is completely conspicuous to the naked eye. There is in-body image stabilisation of up to 4.5 stops with ANY LENS and the total elimination of mirror vibration shake at ANY SHUTTER SPEED. Whereas you wouldn't shoot handheld at 1/8th or 1/15th of a second previously, it'll end up being your favourite range of low light setting on a mirrorless setup (ask the NEX & m4/3 users who similarly do not have mirror limitations).

Its a massive leg up over a D600 or any other conventional DSLR.

DXO can never take those factors into consideration can it?
