Interesting UV filter test

Thanks for the link.

They seem to have only tested the quality of UV filtering, not the coating and how easy the filters are to clean.

This being said, I really like my Hoya HMC filters.

The B+W mc filters are a pig to clean, but they are brass and don’t get jammed on lenses like the cheaper ones
 
Interesting to see the additional reflections in the "with filter" side-by-side tests for individual filters. The sun is hitting the filter at an oblique angle for these shots -- one of the reasons I had resisted filters, except for special effects (e.g. red filter to darken skies on b&w film), until I started using an M8. I did have a 52mm filter save the "life" of a 28mm Nikkor that a friend did not realize was in a canvas bag he threw onto some stone steps. CRUNCH. The filter was trashed. But the lens was fine and 18 years later I am still using it.

I am yet to put a cleaning/coating mark on my B&W filters while the hoya are so easy to damage...
When cash and availability are not crazy, and for important lenses, for me, it's B+W all the way...
 
i I have B+W on my 50 cron and just ordered a second one for my new 28 elmarit. The reason I go with B+W even though they're not available locally and I had to order them form Ffordes, is because they're the only one available in 39 mm size. For my canon and nikkor lenses though I use Hoya filters bought locally.

B+W also make MRC filters with alloy rings that are sold on eBay. They are less expensive than the brass filters and the glass is identical.
 
In the latter categories [flare, vignetting] the MRC filter has no flaws. It is worth adding that the B+W filters have the best build quality and they are very easy to clean.

Other than UV filtering, B+W MRC filters are as good as it gets.

How many of us buy UV filters to filter UV? :rolleyes:
 
Rub a little candle wax on the filter threads. It doesn't take much. It solves the sticking problem with aluminum filter threads.

Don't obsess too much about having totally spotless filters, and it's more important to have the back of the filter clean than the front. It's mostly the light getting bounced around BETWEEN glass surfaces that degrades the image.

BTW who buys giant 72mm filters? The Nocti is 60mm and its the largest element in the lineup.

Canon FD 200mm f/2.8
Canon FD 20mm F2.8
Canon LTM 50mm f/0.95

...all use 72mm filters. Not quite as large as a saucer, but as large as a medium sized ash tray (for those of you who remember ash trays).
 
Starbucks still has ashtrays on the outside patio and I have them throughout the house, including the darkroom. Got a roach clip or two also just in case.

Doesn't anybody remember the old trick of blowing a cloud of smoke under the enlarger lens when you wanted just a bit of diffusion?

I never did that, but it's a great idea.

I was always afraid of a cigarrette in the darkroom putting out too much light.
 
Looking at the data, visible light transmission seems to be the highest for B&W. That to me is most important. Time to change to B&W.
