Suggesting 35L for every full frame shooter who can afford it.
I got rid of 17-40, 24-105 and almost got rid of 50 1.4 after acquiring a 35L. It's currently my only wide angle. It's that good.
After shooting with L primes, those f4 zooms will never be enough. To get good sharpness you have to stop down at least 1 stop, and f5.6 is not acceptable in low light.
The next target is 24L II, damn the L lust!
+1 on the 35 and 24Lii. I just had a 24*36 print made from the 24L shot wide open and it's just amazing.
