>From the pictures I have seen its a non issue on the D7100. I'm sure it can be induced though. It's the nature of the bayer pattern. The Foveon avoids it because there is no interpolation. The Trans-X avoids it because IMHO it is sacrificing fine detail due to the way the sensor is laid out and the resulting image is interpolated. Look at the 5d mk2 comparison at dpreview and compare to the x-pro and k-5 iis. The k-5 is neck and neck with the 5dmk2 which has an AA filter. The x-pro doesn't come close to either, but the resulting image looks very sharp and gives the illusion of greater detail. This is my opinion, but I compared these cameras for a very long time looking at different parts of the scene and came to the conclusion that the k-5 iis can compete with 20mp full frame. I eagerly await a 24mp aps-c sensor from pentax. Too bad most of my glass will be likely outresolved. Especially my newer DA zooms. I expect some of my older glass to hold up fairly well though. Primes especially.
I believe that quite a few MF cameras had removable AA filters. The sigma SLRs have a glass piece in front of the mirror box that you can remove for IR photography. Kind of cool actually. The nature of AA filters probably requires them to be sandwiched on the sensor. I don't know what is more reflective honestly. I bet the D800 without the AA filter has a pretty shiny sensor too. There is quite a bit of metal in between the actual photo receptors along with wiring that is actually in front of them as well. Which is why BSI is all the rage in small sensors now. All the glass and microlenses in front of the sensor are probably fairly reflective as well. Its probably why the AA filters are covered with multiple layers of coatings.
