Problem? Polarizing Filter
Dec 5, 2015 17:34:17 #
Over the last 8 months I have bought 3 Hoya PRO1 Digital CPL filters for my Canon EF 100-400mm "L" Mk II. The first two I bought from an Ebay retailer at a price that was too good to be true. With these two I could not get a sharp, focused photo - both were returned. I attribute that as a learned lesson and figured they could possibly have been counterfeited.
I just received the third filter from Amazon. I went out this morning and shot 200 pictures. All were just not sharp at all - out of focus.
Has anyone had a similar experience? I've always used Hoya and all have given me quality results. So, am I doing something wrong with a CPL? I did four exposures of each subject turning the filter 90 degrees with each exposure - all were out of focus.
Any thoughts?

Hoya does make excellent filters but for some reason they sometimes have a smearing issue when cleaning. That may be your problem here.

Do you really expect any answer other than speculation and WAG when you don't bother to post a pic showing the problem?

I haven't had any problems.
I use B+W brand and buy from B&H.
A high price doesn't guarantee best quality, but cheap is cheap.

IF you use autofocus, any filter can run an interference. Best bet for you to know is to shot a few pictures using manual in order to identify the problem.

At an air show with my brother, right before an f-15 display he handed me a CPL to try on my Canon 70-300mm. My next 100 shots, each and every one, were out of focus - no keepers!
After removing the CPL all the subsequent shots were fine. I've heard of other people having similar experiences. I can't explain why, but it's obvious that some CPLs affect some autofocus systems for some reason.

Rongnongno, I appreciate your response and will try the manual focus. That is an interesting thought. Would a UV filter have the same potential effect?
Thanks again!

kmohr3, glad to see it isn't just me with that problem. Check Rongnongno's response for a possible explanation.
Thanks for your post!

Do you really need a picture posted to understand "out of focus" means?

Thanks for responding. FYI, like any serious photographer I am meticulous about keeping lenses and filters clean from dust, smudges and everything else that might degrade my shots.

So, what your saying is the higher the price the better an item is? Flawed logic.
