Only with the ZV budget scopes and they have surprisingly good glass, I have had no issues with three of them. Used the Minox BA 8x30 and they just didn't stand out although they were acceptable. I was alternating them with a pair of Leica Trinovids so not a really fair comparison, also a Zeiss Terra which had it beat also, but not by a lot. These were 8x40 so that alone could give the edge to the Zeiss.

I have been interested in the other scopes as the entry level one was so good. Not sure why they are not more popular.
