>>3105368Even at f/16, the final few mm's of the image circle are a little streaky, but nothing that would concern you in a real photo. CA is not too bad at all, and probably less noticeable than it would be on a higher resolution lense, distortion is surprisingly good.
As the based god says in the scriptures, lenses don't make sharp photos, photographers do. Happy with my $25 purchase, might give it to a pentacks shooting qt I know.
