I am trying to get an idea about filter use. I have read up quite a bit on filters, but I still am not entirely sure about what I should really use. I just discovered that my 28-80mm f/3.5 67mm dia lens won't work with filters (I get vignetting otherwise). The 50mm f/1.8 49mm dia prime works fine with them and I am guessing my 135mm f/3.5 47mm dia lens would work fine with filters (I have none for that lens).
What should I absolutely get? I have a skylight, polorizing, and netrual density +2 in 49mm dia and a polirizing filter in 67mm dia. Will a UV or skylight filter really cut down a lot on bluing from haze at long distances? Or is it only going to be a slight reduction?
I am still trying to figure out how to mount at least a thing filter on the 28-80mm camera, but with just the filter ring attachment on the lens there is a bit of vignetting at all zoom ranges with a wide open aperature (none at F16 or 22). I think there is enough room on the filter ring attachment to file it down 2-3mm and still be able to fit a filter on it without it hitting the lens. Do you think I should go to the trouble just so that I can mount a skylight or UV thin filter?
Also the lens is setup so that it has male threads on it to attach the filter attachment ring so that female threads can be used to attach filters. Would a bump-up filter adapter attach using female threads as well? I might be able to take care of all of my vignetting problems if I can go to 72mm filter sizes so they are far enough out from the lens.
Sorry for the load of questions, and thanks.
