Is it OK to use Polarizing filter with Step-up ring on top off an UV filter? I just recently purchased my first ever polarizing filter... B+W 77mm MRC. The filter size for my lenses are 52mm, 67mm and 77mm. So I purchased 52-77 and 67-77 Step Up rings. In this setup, every time I intend to use the polarizing filter, I have to take off the UV filter and then put on the step-up ring with the polarizing filter. To reduce filter changing work load, I was wondering whether it is OK if I don't take the UV filter off. In this case, I will have UV filter, Step-up Ring and then the polarizing filter in front of my lenses. My lenses are 12-24mm f/4, 35mm f/1.8G, 85mm f/1.8G and 70-300mm VR (All Nikon Nikkor lenses). Currently I have regular Tiffen UV on all my lenses. If using UV + Step-up Ring + Polarizing filter setup can be used without too much image quality compromise, I will think about upgrading all cheap UVs to a good quality multi-coated UV filter. Please advise.
