I have fitted the 10x42 to my rifle. I find head position is crucial as I either have a clear picture or no picture. A slight move of the head and I can see nothing.
When I have a clear image through the cross hairs I don;t get a really sharp edge to the picture. The bottom half of the circular picture has a very sharp edge but the top doesn't. I have tried all sorts of head positions, but I can't ever get a perfectly defined circle all the way round the image.
Is this just me poor eyesight, or do others experience this too. I don't get it with my Viper or Mamba.
Other than that I like it. Good depth of field as everyone has said.
