If anything, it's sharpness should induce moire - moire occurs when a pattern's lines match the size of a pixel on the sensor, and sharper lenses will allow for finer lines.
Good to know. In any case, no moire noticeable on hundreds of pictures.

It doesn't quite work that way, the pattern has to be at a very specific spatial frequency and it has to repeat across a reasonable area of the sensor to be recorded as moire.

Thanks for the clarification - it was always explained to me in the way I described it.

Lovely pictures. I am looking for a good macro lens. .... 70 sigma looks sweet but no aperture control for extension.

Nice one!
I don't have the K5IIs yet, as I opted to put my funds in a Sigma 500/4.5 first, but I will go for it as soon as I can afford it. I love almost every image I see from the K5IIs, and the Sigma, being screwdrive for Pentax, needs the best AF possible in a Pentax body.

I didn't nail the focus but the tiny 'hair' on the main stem can still be seen on original size;




check out the original size for the iridescent scales of this predator;

Thanks John, I was walking along a jetty and the pelican just popped up and over. It was a quick reaction shot that worked. I wish they all did!!

I've had my IIS for two months now and I just keep getting pleasantly surprised at the IQ. The only problems I've had with moire are acute angles to corrugated iron sheeting and the mesh in fine shade cloth both of which I could remove or reduce significantly through LR4 and scaling.

Regards,

David
