p.1 #1 · p.1 #1 · Lens has become unsharp, has bad glare (70-200 2.8L IS) | |
My 70-200 has been with me for quite a while, but in the last year or so it seems to be getting worse. I mostly shoot with a 35L and 85L, so for a while I wondered if it was just not up to par anymore.
I don't have sample images uploaded, but I can quite easily describe the problem:
- Focus rarely is that sharp, stopping down helps only slightly
- Occasionally get a ghosting OOF effect, like it's slightly backfocused or frontfocused, even though it's not
- REAAAALLY bad haze/glare anytime I'm shooting even remotely toward a light source. There was a bright (albeit north-facing) window above the couple at a wedding recently, and all of my images of the ceremony are incredibly low contrast
Is this something that happens if the lens gets bumped too many times, or is there dust in the lens perhaps? The glare especially is driving me nuts.
Side note: I use CPS, but have had really poor luck with them (a few times they returned lenses unchanged)
