Do the users of this lens find it hard to create separation between subject and background? I'm just saying it... On a general basis... Do you see much pop in your pictures?
I'm just basically wondering if f2.8 is thin/fast enough for me. I've had the mark I in the past, and now have been wondering if I should just buy the 50L and save a grand for the 200 f2L. Hmmm. The 2.8 is a staple lens.
On full frame...yes. Plenty of separation. I actually like shooting at f/2.8 on full frame...enough DOF for portraits most of the time, but still good background separation. It's why I went to the 100L as my portrait lens (among other reasons).
For instance, here's a shot at 95mm and f/2.8...not exactly a recipe for huge amounts of bokeh, but the separation is really nice;
And, of course, at 200mm and f/2.8, subject separation is quite easy:
