Re: Nikon D800 announced -- 36mp, w/ & w/o AA filter
theSuede, reading your post is a good learning experience.
If I am wedding photographer (depend on how I am mostly shooting), or professional frequently deal with production shot. I will choose D800.
D800 and D800E has the exact same resolution, but different contrast because AA filter. so image will look sharper generally with D800E, assuming there is no Alias happen.
(I am not so sure about below statement, I am listening.) Without AA, The sharper image is not come from Spurious resolution or alias or whatever its called. It is from no smudging the high frequency contrast by AA filter.
It is controversy, at one hand, you want image to be as sharp as possible, at other hand you don\'t want it is too sharp to capture a lot high freq stuff alias to your image. BUT, BUT, this is only happened at:
A. You have extreme sharp lens out-solve sensor.
B. You have a case have many high freq pattern in your image. For random stuff like most landscape shot, I doubt there is any frequency spike out there, other than high freq noise floor way lower than your Camera DR can capture, even there is alias, this is not a issue. Again I could be wrong, I am listening.
So far, most moire example, I see is either fabric, or chart at lab to exaggerate the issue. Theoretically, without AA filter, you will have alias. Real world, you have AA filter in front of your sensor as listed: lens, camera vibration (Not exact sure how this will affect things.) and diffraction AND having fixed high freq pattern in your image AND will it to affect your image? AND can you fix it in PP?
All in all, chances you get screwed are low.
Experience can tell you past, but there is no such high pixels density AA free camera exist before. How does it apply here?
