How is your experience using the Camdiox focal reducer? I’m in the market for a focal reducer and was looking at this one as a cheap option but wasn’t sure about the optical quality.Great lens!
Unfortunately my copy is broken, seriously decentered, so it works almost like tilt-shift lens and I cannot obtain infinity focus. Because of that I don't use it too much but even with this handicap it's beautiful lens sharp from wide open.
Only real drawback are older anti-reflective coatings but if one isn't shooting directly to the lights it's without problems and contrast is pretty good.
All images were taken with E-M10II and Camdiox focal reducer.
First two images are at f/2.5 (f/1.8) and third one is at f/5.6 (f/4).
