Zeiss Terra or Vortex Viper

A percentage of people (1% roughly) have problems with the field flattener lenses that is makes up Swarovision. Its all about how your brain processes signal from your eyes. The SLC's and most other glass show a curved image, similar to what your eye sees, this leads to the minor-major edge distortion you see in most glass. The field flattening lenses give you a flat image with no edge distortion. Its more prevalent in the smaller 32's if you are wired that way. That being said, a lot of people who notice it in the 32's and 42's won't see it in the 50 mm objective glass.

Avery you are not alone, I've looked through probably 15 different pairs and noticed a range from garbage to less shitty.

If a person wants to get into optics and get the best info.. Its not on hunting forums, its on birding forums. Those guys take testing to a whole new level using very objective tests.
