[Glass] From the time of their introduction to the market, panchromatic emulsions have been know to retain some of the sensitivity to blue light than the human eye does. Modern emulsions are better, but still benefit visually with the use of a Wratten #8, a.k.a. K2 yellow filter. Being a throwback stubbornly devoted to film, my lenses always have a #8 aboard, whenever I’m making black and white images, unless other contrast control filters are needed for specific circumstances.

I can’t say I have done any technical comparisons between the actual bandwidth of filters manufacturers, but have used Tiffen filters for years, with no problems. My only minor gripe is they use aluminum instead of brass rims, which can lead to more frequent jamming, unless extra care is used when installing them. In a perfect world, they would use brass for their rims, and maintain their price point. And my car would start reliably at temperatures below freezing...

Users should always keep a filter wrench in their kit when using these. I also treat my filter’s threads with a VERY LIGHT film of synthetic lubricant like SuperLube or Syl-Glide.

Avoid lithium grease for all photographic equipment! It’s reactive with most of the alloys used in our precious gear, and degrades into a hard cheesy mess over time.

Anyway, Tiffen filters have never disappointed, and are a fine choice, compared to the pricier brands. Of course, ULF users probably could care less, but still—

[0.52 lb] I use this for B&W photography and it works as advertised. I haven't used any other yellow filters on this particular camera (so I cannot make a comparison between brands), but this is a great value.

[0.52 lb] I'm pleased with both the quality and the price of Tiffen products, this filter fills the bill.

[0.52 lb] Have always purchased Tiffen filters. In my opinion thay are the best filters out there. Great glass and dyes. I have Tiffens that are over 30 years old and still are as good as the day I purchased them.

[Glass] Work as described

[0.52 lb] Consistent tone and clean glass threads on nicely and seems to be well made

[0.52 lb] Planning to use on AC system dye. Haven't had a chance to try it yet.

[0.52 lb] Great for landscapes or cityscapes with big skys

[0.52 lb] I've decided to standardize on 77mm filters going forward. That way I need to buy only one of each color/type. I have no plans to buy or use any lens using filters larger than 77mm. I'll use step-up rings to adapt the filters to those lenses I use that use smaller diameter filters. this filter is a quality item and I've rated it at '5' for that reason.
