FA31/1.8 Ltd is different lens. Smaller, lighter and with very special image characteristic. Not to mention some (small) difference in angle of view. Comparing these two is a bit apples vs oranges.
But its nice to have this 35/1.4 option, as new FA35/2 now costs silly amount of money and DA35/2.4 is optically good, but cheapo-build lens and not that fast considering aperture..
This sigma 35/1.4 is faster, shows better bokeh and might also be as sharp as FA35/2 + have a bit less CA.. but also is bigger, heavier and I’m not sure about carrying it a lot instead of my FA35/2…
Btw, Sigma, I’d like to have some small 10mm F4 rectilinear lens, please 🙂
Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
