Sigma 35 or 135L??

Look at your shooting style and get lenses that fit your style.

nailed it

Just did a metadata search on LR, most of my shots are either at the wide end (17mm - 28mm) or the tele end (mostly around 85mm). I also tend to crop a lot. So I guess my style is a mix of wide and close-up.

Next experiment - stick my 17-40 on 35mm and shoot at that focal length all day, see how it goes.

one of my favourite combos
has always been 2 FF bodies 1 with the 16-35 f2.8L II and the other with the sigma 85 f1.4
it gives great coverage and flexability, especially for events

While you're at it, since you have the 50mm 1.8, compare it with 35mm to see whether you think 35 would be much more useful than 50. For my taste, on FF 35mm is too wide most of the time, partly because I prefer not to get very close to the subject, especially if the subject is a person. My inclination is to go longer, and would take the 135L for the reasons given by others. (That said, the Sigma 35mm is so good I've found myself going out of my way to find way to use it, which has been a rewarding experience in itself....)
