In the video of Lindsay Adler I saw she has a Sigma 35 1.4 Art AND a 50 1.4 Art.
Doesn't this is obsolete only 15mm difference!
The bokeh/dof cannot be such a big difference for only 15mm, it's only 1 step closer.
I know a 24mm & 35mm is a big difference and also fov, but 35 & 50 ?! I doubt this...
