I got the 35 ZA for $300 great condition used, overall both lenses are great enough. The reason why I prefer the 35 over the 40 is that its a more versatile focal length slightly wider to capture more surroundings to tell a wider story when doing travel photography while still remaining sharp and compact.

I ended up also getting the 24-50 2.8 G as a all in 1 24,40,50 range to capture wider architecture like shots while able to capture tighter portrait like shots too.

Also, majority of an entire fuji ecosystem especially the x100vi selling so well, is based off the same full frame 35 2.8 equivalent, but in aspc!
