comment:Focal lengths between 40 and 50 are my most used, with 40-45 being my favorite.I was satisfied by Sony FE 50mm f1.8 image quality but really annoyed but it's noisy and slow AF on my A7ii.

The build is very plasticky, but tighly assembled. The upper side of this is the lens is extremely light. But even the mount is plastic as I see it (others think it's metal, I hope they're right but i have a hard time believing it). It worries me concerning longevity.

Image quality is clearly above the FE50, sharper from wide open, more contrast in details. It's very good where it matters wide open, and gets stunning everywhere stopping down.
Only points where it's not perfect are
- the strong vignetting at f1.8 (becomes less noticeable at f2.8). It needs to be corrected in post if the subject is out of the central third of the frame.
- and I think it has a tad more distortion compared to FE50, but that would only be noticeable on architecture and correction would not result in poor corner sharpness like on the FE28.

AF is satisfying, i'd say between FE85 and FE28, and infinitely betetr than FE50.It is not completely silent but not noticeable for stills, and hardly noticeable in video if you use an external microphone.

In summary, it makes top notch / very pleasant pictures and it's super light although the trade-off is a very plasticky body.
It's by far been my most used lens since I had it (about 3 months).
