Recommend a UV filter for analog SLR

Recommended Posts

<p>I've got an Olympus OM-1 and two Zuiko lenses, 28mm 2.8 and 50mm 1.8, and I'd like to get a good UV filter for each of them. I use lens hoods, so the filters will need to be threaded in the front.</p>

<p>I had a B+W 010 MRC XS-Pro Nano (or whatever it is called) for a Fuji digital camera I had until recently. I liked this filter as it was very easy wipe off smudges and droplets. However, it is not exactly cheap ...</p>

<p>Any recommendations will be appreciated. Thank you.</p>

<p>Following the recommendation by Bob Atkins on photo.net and on his own site (http://www.bobatkins.com/photography/technical/filters.html) for a filter to leave on all the time, I've been using Hoya HMC filters, which do their job and avoid reflections. I like them very much.</p>

<p>Lovely camera, BTW, I miss mine, my first SLR.</p>

<p>Use a premium quality filter with multi-coating to reduce flare. I use B+W filters, which are cut from a slab and ground on both sides. The ring is brass, which is less likely to deform and seize than aluminum. IMO, the filter should be made as well or better than the lens it protects.</p>

<p>Nothing removes the effect of haze and UV as well as a polarizing filter. Again, you should pick one of the highest quality. Unlike UV filters, circular polarizers tend to be expensive. Kaesemann filters have sealed edges to exclude dust and moisture. Moisture will permanently damage an unsealed polarizer, which consists of one or two plastic films between two layers of glass.</p>

I personally can not see any systemic difference in filters for digital vs analog. Over the years I have used most major brands. Tiffen, Hoya, B&W, Heliopan, Canon branded, Vivitar, and lately one by Sensui. Circular polarizer is the only one to use for digital. If you value thinness in a filter, go for the premium brands. I cannot speak for coatings. They all have coatings. I treated filters like lens elements and kept them blown free of dirt or wiped gently with a lens fiber cloth or tissue. Cheap is relative term and I figure they are worth it relative to the lens. But lately, I go naked on my lenses and they thrive.

<p>There are ceramic filters which are nearly unbreakable. I don't know how good they are optically, but they're sold for photographic use. Might be worth some investigation.</p>

<p>UV filters are, AFIK, worthless for removing UV. They are mainly for lens protection. Haze is due more to scattering than UV light, and a polarizer is highly effective on scattered light.</p>

<p>Filters are a good dodge against toddler's fingers and dog licks. My lens looks like a lollipop to my sons' [sic] dogs. (Plural. Two of my kids have the dogs I never allowed. Cats don't lick lenses, or faces either. In fact, they ignore you unless they're hungry, then they bite your ankles. Toddlers can do anything they want, and I'm okay with it.)</p>

<p>Just received a B+W F-PRO MRC filter - beautiful build quality, I have to say.<br /> One silly question, though: The front thread on my 50mm is slightly damaged, so I am not able to screw the filter all the way in. I guess we are talking about 1.5 to 2 turns (see attachment). There's no way the filter will come off by accident - I can completely fasten it, but it doesn't go all the way in. Will it matter optically?</p>
