Although, for some, this converter will never give them the performance they expect from a dedicated prime lens, so long as you're aware of its few weaknesses and use it accordingly, it can yield excellent quality images.
Good build quality, Excellent sharpness when stopped down, Focusing seem unaffected by the converter, Automatically detected by the camera/lens, Not too expensive, Low distortion
Sharpness at maximum aperture, CA at maximum aperture, No, thread
The adapter is excellent, I'm just annoyed that the lans cap does not work! it is does not secure tightly. Its been a pain in ass trying to even get response. I just need a replacement lens cap, everything else works beautifully.
Heavy, but serves its purpose. I like thw idea of not having to swap lenses and risking getting dust on my camera sensor
Loving my wide angle pics
Very happy with this purchase.
I guess I was expecting more considering the price. This conversion lens is a biggish heavy pice of optics that snaps firmly onto the host 28mm f/2 using the lens shade ring. Edge to edge illumination is excellent with no noticeable drop off.
Fit/finish and ergonomics - definitely 5 stars. Construction quality is stellar. Metal barrel with built in plastic hood. Usually I hate built in hoods but this one is very unobtrusive. Very easy to install onto lens.
Even better than my original 16mm pancake with wide angle conversion lens. This comes as close as you'd need to a higher end Zeiss glass like the 35mm f/1.4 and the 28mm prime is among the top 5 lenses tested by DxOMark.
A quality wide angle adaptor for the 28mm F2.0 Lens. Fits very well and the build quality is wonderful. Happy with the image quality. Some CA but generally fixable in post processing.
