comment:This is the most expensive new lens I've purchased--about three times the cost of the Canon 50mm F1.8 STM. It is currently $100 cheaper than the large Tamron SP 45mm F1.8 VC USD.

I've enjoyed this focal length since purchasing a Minolta MD 45mm F2 back in 2016. I haven't been using the large Tamron SP 45mm F1.8 VC USD much. My copy is sharper than either copy of the FE 50mm F1.8 I've tried. It performs much like the slightly larger Sony FE 55mm F1.8. It focuses very quickly and quietly.

It is comically small next the Tamron SP. Unlike the simple Double Gauss/Planar design of the FE 50mm F1.8, the lens elements take up the entire length. The optical design looks more similar to the Sonnar 55mm F1.8. Zeiss would probably label it a Sonnar.

The 49 mm filter thread diameter is shared with the Samyang 24/2.8 and 35/2.8 primes and many Minolta and Sony lenses. The hood bayonet is shared with the 24/2.8. The included circular hood is only slightly larger than the 24/2.8 hood.

Wide-open this lens has the outlined background bokeh like a lens over corrected for spherical aberration. Meanwhile the Sony FE 50 F1.8 is under corrected and renders backgrounds more like an STF lens.
