Scratch on Polarizing Filter
Oct 7, 2017 09:37:17 #
I some how got a scratch on my 77mm Canon polarizer, it's about a quarter inch long. Will have an effect on future pictures? I appreciate your wisdom.

In some cases, if the light hits the scratch just right, yes, it will affect the captured image. However, the chances of that happening are slim, since you probably won't be pointing the CP in a direction that would allow that to happen.

Chances are it won't show up in your images but, the only way to know for sure is to take a series of sample shots and then examine them closely in your post processing software and see if there is any affect.

I doubt that it will have any noticeable effect on your photos. Many photographers with more experience than me say minor scratches on a filter won't have any effect on your photos. But I'm glad the scratch is on your filter rather than on your expensive lens.

Bob's answer is correct. My advice is to get a new filter and not worry about running a great image.

Very easy to find out, put it on and take a few shots, then you will know! A lot of times scratches don't show, but they can, it depends on their location and size!I some how got a scratch on my 77mm Canon polarizer, it's about a quarter inch long.

There are glass polishing products on the market that can help. If you spent a lot for the filter this might be cost effective.

I would be reluctant to using "glass polishing products" on expensive filters. You will probably destroy the multi-coatings used on most good filters.

Aren't you glad you had a filter and did not scratch the front lens element?

I have a small scratch on my 24-105mm near the edge. (Made a mistake of not having the UV on it) It so far has not made a noticeable difference but I use a hood and worry about light hitting it.

If you point your lens into the sun the sun could bounce off the scratch and play games with reflections inside your lens, MAYBE. Why not just shoot a image, one with and one without the filter on and see if their is any difference. If your lens shade attached I doubt it will effect anything.

It will probably have some effect on images if used on wide angle lenses.
It's less likely to have effect if used on a telephoto.
It also will be more likely to have effect in flare inducing situations, when oblique light is striking the filter. Using a lens hood can minimize that. Also using a black pen to fill in the scratch will minimize the effect.
If you decide to replace, Canon C-Pol are nothing special. Not bad, but not top of the line either. They're probably outsourced from Kenko or Hoya and are uncoated. In 77mm size you can get a better quality, multi-coated B+W F-Pro MRC C-Pol ($79, 8-layer multi-coated, high transmissive, brass frame) or B+W XS-Pro C-Pol ($102, 16-layer Nano-multi-coated, high transmissive, slim brass frame) for roughly half the price of a Canon C-Pol. ($195... all prices at B&H Photo, NYC). Marumi, Hoya, Breakthrough all offer some better filters for less than the Canon... though they're all higher priced than German made B+W filters.
