Terrific performance. Effectively no chromatic aberration detectable by eye, and minimal even when pixel-peeping photos made in combination with the (separately purchased) TE-11WZ 25-60X zoom eye-piece.I have hooked the Kowa up to a Fuji X-E2 camera using the following items (in addition to the 25-60X Kowa TE-11WZ eyepiece):1.

    It feels super durable and high quality and the focus is easy ...
  

*by J***S on Reviewed in the United States 🇺🇸 on August 21, 2017*

OH MY GOD. This thing is incredible. Far exceeded my expectations by miles. Paired with a fixed 30x zoom eyepiece it rivals any Swarovski I've looked through. It feels super durable and high quality and the focus is easy to operate. I have never been so pleased with an optics purchase. How is this thing so cheap and why do more people not know about them?
