Re: Am I not worthy - I am not worthy...of stellar lenses
However in the spirit of cooperation I will reword my original post without the hyperbole.
My testing of the 50mm Air showed that it did not match the Tamron 35mm lens in the corners at MTF testing distances. This is probably attributed to field curvature. The T stop of the lens is also demonstratably significantly darker. I have noticed a lack of tonal separation in the shadows which I have never seen before in lenses to this extent though it can be fixed to a degree with a custom ICC profile which is what I did. I found a significant lack of accuracy using AFC focusing on two copies of the A7r4. It is a fun, cheap lens that punches above its weight however I personally do not find that it can compete as a package to the extent that some reviews might be suggesting. YMMV.
