Those Moiré patterns look different on the full image if you click through it. I would hazard a guess it is just the usual type of interference between the cages and the colour filter on the sensor. _________________ Mark

Odd that that effect shows more here than it does on the hosting page.
I ran into that once before with the Kino variant of the vivitar series 1 80-210 at about 180mm in daylight on some building siding that was close to medium grey in color with a weathered tone. I think I may have dumped the images over that effect. I'll check to see if they are still on one of the cards later.

MFLenses can re-scale images as part of the upload process, but the images can also be rescaled by the user themselves before uploading.
The Moiré pattern and colour banding will be affected by the scaling re-sampling algorithm used. Even the OS and browser's graphics rendering engine do some scaling and can therefore affect the Moiré pattern and colour banding.
It is an inevitable problem with digitised images when the subject detail spacial frequency gets close(~ish) to the spacial frequency of the sensor sampling, sensor colour filter pattern, display pixel spacial frequency and pixel colour topology.
It is one of the reasons I prefer to do the rescaling myself before uploading my images here; it gives me better control of what the final image will look like, although still not 100% predictable how it will look through the user's graphics rendering engine & screen. _________________ Mark

I did rescale the images before uploading on Flickr but I admit that there is often differences between the uploaded image and the end result, plus the effect of any resampling action on the forum itself...
Having said that the resolution of this lens is very high which increases the chances of causing moiré. _________________ Lumens Pixel

I've been suspecting something like this for sometime now, and now that I think of it, that effect has shown up to varying levels of detection in my images. In most cases, it's subtle enough to be almost un-noticeable. The other lens of mine that has a penchant for it is the 55mm f3.5 micro-nikkor at non-macro ranges.
Interesting discussion on the causes here!
