Sony SLR Range

Hi,

while I continue loving my A850 with its big and clear OVF I have to admit that under many circumstances and for many uses the EVF of the A99 isn't far - and ahead of what an OVF can offer in terms of info readlily visible when photographing.

Let's face it, some type of auxilair system is always necessary. Be it a slamming mirror for composition with some part reflection of light towards the AF sensors. Be it a fixed traslucent mirror for reflecting a part of the light to the AF system. And when every metering is done one day off the main sensor, then I don't see any possibility for an OVF. What counts is what works. And both OVF and EVF work. And each system has its advantages and shortcomings. What I noticed clearly among the shortcomings of the OVF is the combination of the mirror vibration and increasing MP count (resolution). This effect I saw commented some yeas ago in an article by M. Reichmann about a 80MP MF back where the "normal" 2s selftimer period proved to be not enough to make vibrations damp to get optimal results on such a high resolution back. Similar comments arised when the 24MP FF arrived and things got only more complicate with the 36MP Nikon D800. Here the fact not to have a moving mirror anymore has clear potential for improvements.
