1. UV Protector: I use a UV filter on each of my lenses 100% if the time, and it’s almost always a Tiffen UV Protector because they’re uncoated and therefore easier to clean in a motel sink with soap and water without damaging them. Another advantage of using Tiffen filters for physical protection is that they’re internally laminated, so they remain in one piece instead of shattering into shards when they’re broken—kind of like the safety glass in your car’s windshield. I also use multicoated UV filters on certain lenses that have flare and ghosting issues. In the days of shooting film, and when I was using the Nikon D1H and D70 I employed an 81A filter to get the warmish color rendition I prefer—especially when shooting Fuji Velvia film. However the Nikon D200 and D40 and the Canons I use today have a warmer color balance so regular Tiffen UV Protector filters work great.
