I recently traded in my 3 Sigma Art primes, total weight > 6.6 lb. towards a Z FX camera and a Z 85mm f/1.8 S. Still in the learning curve stage I am satisfied with the camera and lens. Wanting a wider FOV I bought a used Z 35mm f/1.8 S at a bargain price but comparing results vs my former Sigma 28mm Art + same #MP Nikon DSLR., my results were disappointing. The next day the used lens went back to the store; I bought a used Z 50mm f/1.8 S for $229 less than new and it is a keeper. It that reminds me of a Sigma 50mm Art without the focus issues and weight.
Reading the PL review of the Z 24mm f/1.8 S:"...Although the lens does not reach the same resolution potential as the Z 35mm f/1.8 S and 50mm f/1.8 S lenses, it still performed admirably when stopped down..." So I wonder if this particular used Z 35mm was a poor copy? I liked the 35mm FOV, looked ideal for low distortion for family group photos, but compared to my 50mm/85mm and former 28mm Sigma Art lens, overall and image edges were noticeably less sharp. I might try to get by (or back up) with my 50mm.
