Can I use Circular Polarizer like a UV Filter to protect the lens?

[Sean Setters]

I'd have to agree with btaylor. Some filters are still quite relevant in today's digital age. The circular polarizer, in my opinion, is one. I don't think the results can be easily replicated in post, if even at all. And even if you could, it'd probably take more time than I'm willing to spend editing my images.


Another filter that's still quite relevant is the ND filter. There are things you can do with an ND filter in place that you certainly cannot do in post-processing.


Whether or not you need a UV filter on your lens at all times is a matter of personal preference. Yes, any filter will degrade the image to some degree. Whether or not it's worth that sacrifice to protect your investment is up to each individual user to decide based on his/her needs.

I'll be with btaylor too. The CPL and ND do have their job to do even with digital. ND lets me shoot with f1.4 in bright sunlight without my speed go all the way up to 1/8000. I will need to use UV because I actually do shoot film. Just for the sake of protection I also will need them to stay on my glasses all time.
