Since the Nikon D810 got announced yesterday, we have been getting a lot of questions from our readers via emails, comments and Facebook messages. After answering many questions and doing some additional research, I decided to compile everything I have gathered so far in a single article. Looks like the biggest number of questions is coming from existing Nikon DX and D600/D610/D700 owners, who are considering to move up to the D810 as an upgrade. Some Nikon D800 and D800E owners like myself also find some of the new D810 features attractive, but there are still some items that remain unclear from the announcement (such as the camera buffer size), so the below article will hopefully address some of those questions and concerns as well.
1) Nikon D810 has no OLPF / AA filter
This one might be particularly interesting to existing D800E owners. If you remember from our previous coverage of the D800E, the difference between the D800 and the D800E is the filter stack in front of the sensor. Basically, the D800 has two stacks of anti-aliasing / blur filters along with the regular UV / IR filter, which is what effectively reduces moire in images. The D800E, on the other hand, has a blur filter in the front of the filter stack, which is cancelled out by another filter at the end, as shown in the below illustration (a detailed PDF illustration from Nikon is available here):
