Now that I have my trinity of 46mm primes (14mm, PL 25mm, PL 45mm), I'm looking for some quality filters. I'm noticing that this size is not very common and the choices are a bit scarce. I'm looking for some advice on what to get, or should I be considering a larger size with a step down? Since these are my best lenses that will get the most use, I want some decent filters, but not break the bank. For polarizer, this looks like a good deal for a quality brand, anyone have any feedback on this one or a better option for the money? I can't find much info on it and am just going by the brand name more than anyhting. I have a Marumi for my 14-140 that I like, but can't find it in 46mm size. 65-075273 B + W 46mm Top Linear Polarizer Coated Glass Filter Where I'm struggling more is in a a good ND filter. I was really hoping for a decent variable one or something pretty dark, ND16 or more. All I could find were Polaroid and Fotasy options on Amazon, both had some pretty serious flaws in the customer reviews. Anyone know of a decent variable option, or where I could score something darker? I like doing the long shutter daylight photos of water, etc. Also I'd like to be able to shoot wide open during the day with these great lenses. As always, any advice would be much appreciated!
