My take is that it DOES make a very small but discernable difference. Some 5D series nature/landscape photog owners have this ( AA filter removed) done. Canon has been very reluctant to do this on their own because, I believe, they believe, that MOST 5D users are shooting man made subjects ( as a profession) and therefore need the AA. In other words, Canon finds it NOT important to cater to the nature photogs with the 5D series IMO.
Arthur Morris (a Canon guy) feels its not an issue. I am going to spend some time with Christoper Dodds (a Canon guy) this coming summer. I will ask his opinion. It just seems to me, that if the difference is "very small", when you present an image, from my perspective, as a print which is view at the proper viewing difference, a successful image has much more to do with composition, tonality, overall sharpness, lighting conditions, etc., as compared to how many hair or feather follicles you can count. I just feel the discussion is irrelevant from a photographic perspective. Just my opinion but thank you for your response Larry. Sorry for the tirade.

Most Canon guys may say it is not an issue - because they have Canons ( because Canon has mostly not made it a choice for them)
Nikon people will say different - because they do have a choice.
The 5DSR has the AA disabled with software I believe ?? BTW.
Here is what Rockwell has to say regarding 800E/AA filters - http://kenrockwell.com/nikon/d800/vs-d800e.htm

Are you sure Canon can't as opposed to won't?
Actually Canon HAS produced a DSLR without an anti-alias filter.
It's the 50MP EOS 5DS-R and is described as having...
"the low-pass filter* (LPF) effect cancelled to provide even more fine edge sharpness and detail for critical subjects such as detailed landscapes, and other situations where getting the sharpest subject detail is a priority.
*The possibility of moiré and color artifacts is greater due to the LPF cancellation function."
Out of concern for moiré issues, the 5DS-R is not recommended for shots involving clothing, architecture and similar that have repetitive patterns... including the feathers of birds and some and the coats of some animals. For those, the 5DS is an alternative with the key difference being that it does use a low pass filter.

Thank you for the link Larry.
I quote Rockwell:" If you want great pictures, get the regular D800. If you're a pixel-counting nut who spends more time looking at your photos at 100% on a computer screen than seeing your work in print or on gallery walls, get the D800E."
End of discussion from my perspective. Again, this discussion is a fruitless academic exercise for those interested in pixels rather than images.
It is always a pleasure to trade comments with you Larry and thank you!

Yes , it was largely curiosity. Thanks for your reply.
Sorry I have not checked this thread, I was away at the Chicago Marathon and just got back.

I think I will be leaving my filter in place. The cost/benefit just does not seem to be there. In general, I understand that as the sensor capacity increases the moiré issue decreases. I expect that the AA filter will eventually be a rare exception.
