Re: Sony A900 vs Nikon D4 vs Nikon D3s vs Canon-1D Mark IV vs Canon-5D Mark II

I own a850 for 1+ years. My DSLR story started with a100 from 06.

I seriously tried a77 in sony store this weekend, I can feel EVF advantage actaully, espeically for accurate exposure (i'm not a fan boy of birding or action-shooting) + accurate WB. So I would suggest you try it "seriously" as well .

Of course, i think current EVF is not mature enough. I'm looking forward the evf on a99.

in turns of IQ, i can accept that "the negative impact can be improved as invisiable vs OVF version". As most of us will attach a protector/UV filter before our ZA/G lens. SLT mirror will be similar like that, considering IQ impact.

If we choose certain iso speed, it should be able to give as same noise peroformance, comparing to OVF/mirrorless desgin (my guess). Only shutter speed will be slower for about 1/3 EV or 1/2 EV.
I'm actually also studying the studio shoot between a77 vs NEX-7, in RAW format.

So, my question to next FF SLT, will "only" be EVF performance/battery performance/faster response (camera level)/ more options for use to work around SLT-mirror impact in terms for ISO noise ( i strongly suggest SONY provides me a option to flap up mirror, if a shoot needs to stay as low as iso speed & as fast as shutter can get (OVF advantage)).

Just have observed studio shots from these cameras in comparison mode.

Happy I have Alpha 850 (same to a900). It is a king for the price, IQ wise including.
Canon-5D Mark II is the only real competitor to A850/900 so far.

Pity Sony'll be a bit late to the table with new FFs A950 & A99.
Me will consider 24-mp A99 SLT as second body to my A850.
I'd prefer OVF of A950 but 36mp is too much for my needs.
Hope Sony'll not screw up image quality in new FFs.
So far I'm happy with the "old" trusty A850.
