  • Sharp, light, low CA, good FOV for class
  • Slight pincushion, glare when bright sky is in the view.
I bought these because I heard they were essentially a clone of the much talked about Sightron blue sky. They are a great value for the price range of under $200. they are fully multi coated, waterproof, phase corrected, and have silver prism coatings (a nice feature over aluminum in this price range).
Brightness: They have great brightness for a 10x32 roof prism in this price range
CA: Very little and only in very high contrast situations. Far better than most bins without ED glass.
Distortion: Slight pincushion, noticeable while panning but not bothersome.
Blurring at the edge: Focus is very sharp across the FOV with slight softening about 80% out, and really only bothersome right at the field stop. Brightness is also constant across the FOV.
Color: A little muted but overall natural.
Reflections: My only gripe is the glare is pretty noticeable when facing bright light sources.
Overall a great value, would definitely recommend.
