Lenstip tested the Kamlan 50mm f/1.1 lens which you can buy at Amazon US, Amazon DE, Amazon UK, Amazon FR, Amazon IT and Amazon ES. This is an APS-C lens and Lenstip texted the X-mount version. But the performance is the same as on the E-mount:
Pros:
- sensible build quality of the barrel,
- good image quality in the frame centre,
- moderate lateral chromatic aberration,
- slight distortion,
- nice appearance of out-of-focus areas,
- affordable price.
Cons:
- very weak image quality on the edge of the frame,
- some spherical aberration problems,
- huge coma,
- distinct vignetting,
- weak performance against bright light,
- some casualness when it comes to aperture markings.
Ok., own up: who was taken in enough to believe that a lens with just 5 elements, an aperture as fast as f/1.1, and costing just $180 will produce excellent images? Realists, who don’t believe in miracles, cannot be surprised by results presented in previous chapters and they won’t be disappointed. I count myself among them so the summary is going to be positive.
