If the Sigma 50 1.4 is keeping my jaw firmly on the floor most of the time then I'm gonna need to insure my face when I get the 35mm
I found I need to take a different approach with the 35mm.
It's not going to melt away backgrounds like the 50 or 85 etc. instead I use it to show context, while softening the background a little. However it's not long enough allot of the time and needs and 85 to compliment it.
A 50 is pretty much the middle ground, and works great of your using one lens, but I found it would never get used if I had the choice of a 35 or 85 as the 35 was better for showing context, and the 85 was better for subject isolation.
