comment:I've owned their 50mm F1.4 EF mount prime for a few years and rather liked it though I mostly replaced it last year with the Samyang AF 50mm F1.4 FE. The Yongnuo was considerably sharper wide-open in the center than the Samyang, but has more lateral CA. The EF Yongnuo has very primitive autofocus which can work fine in many situations. I do't really like either of these as much as my former Sony FE 50mm F1.8. I've also tried several copies of the Minolta/Sony 50mm F1.4, each one progressively worse than the previous copy. I finally obtained a decent example of the Sonnar 55mm F1.8 ZA.

This lens has not been very popular or even reviewed much. A rather positive review by Marc Alhadeff convinced to try it out. It focuses much better than their EF lens on their adapter. It does focus slower than the Samyang and Sigma primes.

The body is similar to the Sony FE 35mm F1.8 and FE 50mm F2.8 Macro except with an extra focus hold button on top of the barrel. I don't care for the extra controls, but I do appreciate the large rubber manual focus control.

While it does have spherochomatism, it is more subtle. The foreground out-of-focus is more red than purple.
