I use Leica 10x42 Ultravids for field work so the Minox CP's are measured against them! They are VERY SMALL - just what I need when travelling. The build quality is outstanding - silky smooth focusing with no backlash, and no plastic. Images are sharp, contrasty, and well lit - no colour aberrations are evident. A bonus is the immediate change of attitude when skeptics pick them up - their weight lets one know that the construction is substantial - the images confirm it. They deserve a cult status!
Pros: Good optics, great build quality, very small
Cons: Shiny objective barrels
