A test I did on the eos 7D using wide lenses and the caprock filter 1.0.
I've done the chart tests but will show a scene thats most likely to show moire and aliasing.
It includes a speaker grille and monitor vents. Tiny repeating patterns that will trigger moire on the 7D.
Draw your own conclusions.
The caprock has different range for filters from 1.0 to 2.8 and different numbers fit different focal lengths.

Hmm…it looks like things are taking a while to load. Try again?
