CPL on top of a UV protect?
Dec 29, 2023 21:40:25 #
I have a UV protect filter on one of my lenses. If I decide to use a CPL filter, should I remove the
UV filter or is it OK to use both at the same time?
TIA

What focal length lens will it be on?
Ideally? remove the UV, especially if the lens is a wide angle.
My 18-200 zoom will start to see the effects of a second filter encroaching the field of view at about 35mm I think.
Vignetting on the corners.
For a telephoto, it's not so much of a problem.

Actually Longshadow, I have UV protection filters on most of my lenses. 13mm, 33mm, 56mm and a 100-400mm telephoto. But I had the 33mm in mind
when I first asked the question.

I have protection filters on my lenses also.
The best thing to do is try it both ways before you want to use it to see if having it as a second filter infringes on the field of view.

With digital, UV filters are not necessary, except to protect the lens if that's why you use it. The CPL will also protect the lens, so the UV filter is not necessary, and if used with a wide angle could result in vignetting. Besides, I wouldn't want an extra piece of glass in front of my lens in case that could degrade quality.

I don't use a CPL very often, but I do like to have a clear protective filter ahead of my front lens element. I do not see any benefit in using a second filter when using a CPL.

Doesnt matter much, but UHH Tradition is to always err on the extra fussy side (one filter, and make sure your PL costs well over $100).

No hey problemo. 33mm is just the normal lens for APSC.

I still wouldn't use an extra filter when there is no advantage to it.

I'll bet I couldn't tell the difference between two pictures of the same subject with one or two filters.
Yup, knowing biases one's opinion.

But why take a chance?

Why not? One would not know definitively unless one tried it, would they.
Can't take chances I suppose.

Two filters certainly wouldn't make it better.

I have mid-range UV and CPL filters (Marumi - not the dearest but not the cheapest) and found that they made it harder for the camera (D5200) to get an AF focus lock. I don't think they ever prevented focus lock but in certain conditions the camera had to do more hunting. Perhaps better filters or a better camera wouldn't have had that problem, but it's a possibility that you should be aware of. Using both together could be enough to cause AF problems, even with expensive filters. And they might be OK with moderate lighting but problematic with something like harsh daylight (when you're more likely to want them).
