It makes NO sense that a lens doesn't "like" a filter. The only thing that would make sense is the filter is poor quality or defective. I use high quality filters on my lenses and have never had an issue with a lack of sharpness due to the filter and I have tested them with and without filters.
I've always been happy with my 135mm with UV filter, but I will have to see if it can do even better without a filter
- thanks for bringing this up
At a recent event I was taking group shots after moving from outdoors to indoors when my lens fogged up (humid conditions). I removed the filter and kept shooting, something I wouldn't have been able to do if I wasn't using one.
I got my Canon 70-300 DO lens back from CPS with the filter in a plastic bag and a note from them saying for best results ditch the filter. Also 72mm I think.
Wow, what an interesting thread. I have always used a filter on my 135L (Canon 72MM UV Haze). It has always been incredibly sharp. If this is true about the lens (doesn't like filters) then I would be afraid to shoot without it! Probably be cutting myself every time I used it I can already read my subjects DNA with this lens at F/2!
I had a 135L and the minute I got it I put a Hoya 72mm UV filter on it.
1) to answer the op's question: My 135L performed perfect on both my 5D2 and on my 1D mark II
Also performed perfect on a friend's 5D mark II, and on another friend's 7D
I sold the lens to a friend, and he lended the lens to me 1 week ago. I shot with the lens on a 5D,and it worked perfect.
As somebody already said: try at least 2 other filters on your LENS and see what's happening and ALSO try your lens with the current filter on a different camera (or more than one camera)
Try to shoot same situation...
2) as far as filter vs. no filter discussion, I'm not gonna add useless garbage to the 'debate'...
everybody is free to do as they please. It's their glass, their money,their choice.
I was not keen on filters either,but I can't afford expensive lenses and especially when I afford one or two, i CAN'T AFFORD to have one ruined by the lack of filter...
My front element was saved way too many times in various situations from various stuff on both my 24L II and my 135L...
I'm pretty sure that those folks that don't dig filters, when a pebble or something/whatever, will scratch/crack their front element........they'll change their opinion on 'filter usage' quite rapidly...
Hope it doesn't come to that for them to realise it..
There are counterfeit filters around. Are you sure the filter is a Hoya Pro? I didn't read every of all the posts, but did you try it on another lens? How about a different filter on the 135? My guess is that the filter has a problem (real Hoya or not).
Yes the filter is Hoya Pro, unless B&H is selling counterfeit filters that I don't know about
I use the same filter on my 35L and didn't noticed the "hazy" effect, then again, I haven't shot it without the filter. Another possibility is that perhaps the image degradation is more magnified on tele lens than on wide angles. Again I am not the only person that noticed this on 135L, couple of people on this thread did confirmed this.
As "dhphoto" pointed out earlier... "The amount of image degredation will depend on the optics of the lens, the position and type of light, the focusing distance and the coating on both the lens and the filter.
Sometimes this may show up, sometimes not. But there is a difference."
All depends on what you are shooting I guess.
I do agreed that the best thing is to not use protective filters (use hood for protection) if you wanna get the full potential of the lens.

Thank you all for your inputs.
Your problem needs to be isolated down to the root cause..
Trust me, I'd shoot a picture with my UV Hoya on the 135L and one without and you still wouldn't be able to tell the difference at a PIXEL LEVEL... (and not the high-end Hoya filter, just a normal/ordinary one)

Thanks for your input, again I am not the only person noticing this issue. Filter or no filter, as long as my lens is performing fine without the filter, I'm good.

Exactly.
Can you try it on another lens, or a friend's lens with a 72mm thread? Or failing that, go into a shop and test it somewhere bright and clear on one of their lenses?

Before blaming anything try to sort Hoya's UV filters available at BH or Amazon etc and find out difference between your filter and one called Pro1 Super HMC. Box should look like that one:
I can already read my subjects DNA with this lens at F/2!
