That's A-Moiré! (Nikon D7100 Sample Moiré)

The Nikon D7100's unique selling feature is that it doesn't have a low-pass (anti-aliasing) filter, thus maximizing its sharpness.  The disadvantage is that the D7100 becomes prone to color moiré (an interference pattern that produces false color).

In my normal shooting I have not found an example of color moire (I did see moire in the top deck of one of the boat samples).  However, at least one wedding photographer has expressed concern about moire on veils and gowns.  In this post, I have provided samples of D7100 moire patterns.

"A-HA!" many detractors would say.  But there's a plot twist...! Hit the jump to find out.


So here they are...

NIKON D7100 MOIRE PATTERNS
For this test, I used a ski jacket with a very fine (microfiber?) texture.  I used the super-sharp Sigma 35 1.4 at f/8.  I took shots at various distances and orientations.  Here are the results (full resolution versions available):

So yes moire is possible on the D7100 with certain subjects, at certain distances.

I did promise you a plot twist... and here it is: I took similar shots, with a D600, also with a Sigma 35 1.4, also at f/8.  Here are the results:

You can draw your own conclusions about the D7100's propensity for moire, compared to at least one other camera.
