The 85L is a legendary level lens. Everyone shooting SLRs on any platform want or envy this lens or atleast know about it. Unfortunately, I couldn't find a use for one in my bag yet. The 135L is just as good for me.
That's exactly how I felt about it. Really nice, if not tricky, lens to use. I got some great shots.
Buuuuut... actually using a lens is really important, otherwise it's just a couple grand sitting like a rock.
Mine has not seen major use, though I will have to more after this review.
It will hold its value, but it really is a specialized lens ...portraits and still life ...yes....action or moving kids or events with adults...only way to get enough keepers is to just take a lot of shots...which is fundamentally different from the way I work and is less satisfying creatively...and sometimes you will miss the moment regardless.
Can be frustrating...but when it hits...it is splendid.
