I used Nikon L37C multi-coated for about 10 years, alomng with Hoya HMC (stands for Hoya Messy Coating; smearrrrrrrs when you clean it with any medium: Kodak Lens Cleaning Tissue, T-shirt,Flannel Shirt, microfiber cloth, whatever, just smeaaaaaaars the gunk around); Tiffen makes a great hairspray filter / black spraypaint droplet when you want to make a fog or diffusion filter. Uggghhhhh!
B+W 010 is the best filter I've used, on 70-200/2.8 and 300/4 AF-S.
But, realistically, I just QUIT using UV filters for almost all uses. However, when trees are dropping a lot of fine, fine sap droplets or mist during the spring budding-out time, I WILL and DO slap on a UV filter on any lens that will be carried uncapped outdoors. As petrochemist mentioned, sea-spray at the shore is one reason where a filter might be used.
In the years since 2001 when I stopped using filters on a regular basis, there HAVE been some advances in filter (and lens) coatings, designed to repel water, to alleviate water drop rings, and to make filters wipe clean much easier. I have only read about those. Hoya made a hugggge deal out of this. Their coating was so awful compared to Nikon's L37C coating, it was just unreal.
I actually let the 300/2.8 and 400/3.5 and 200/2 VR and 70-200 and 80-200 go "naked" almost their entire lives....still...perfect front elements after up to 14 years on a couple, 12 on the other, 11 on the other...so...
I have seen tests of Marumi (?) filters...seemed good compared to other big brands, esp. in circular polarizers.
