[Aluminum] This is actually my second Clear Glass Filter by Tiffen and I must say that their quality is consistently top-notch. I was only forced to buy a replacement after a mishap in which a camera was knocked off a dolly and sticks and fell on the lens element. While the product cracked (the filter) it saved the camera from destruction, which more than makes up for the price that I paid for the original filter. Additionally, I'd like to comment on the consistent clear elements that offers no noticeable light loss, certainly a plus in low light. Just pop the filter on and never take it off. Hopefully it'll never have to come to this point, but it is necessary protection for a fall or any day to day use.

[0.05 lb] I bought the 81b to help cut out the blue in snow scenes and altho just getting started with, am totally satisfied, it's serving purpose well!

[81A] this is a good filter. I've used 81A filters for years. I know lots of people don't like 'em but this helps punch up my images besides warming them a tad. I use these on most of my outside lenses.

[Aluminum] The 77mm 81A filter is a much better choice then a standard UV lens. Creates warmer tones and brighter colors on overcast days or when shooting with an electronic flash. I'm extremely happy with this filter. I'm using it on a Nikkor 12-24 1:4 G ED Lens.

[81A] I use the 81B all the time on my DSLRs with the WB set to daylight, for scenics where it cuts haze, for flash, backlit and in-shade people-pictures, and in overcast. The light-loss is small and the effect seldom if ever too warm.

Incidentally other colour-correcting/-balancing filters are still useful, keeping the same daylight WB. That setting is right for interiors lit by incandescent or fluorescent, with an 80A or FL-Day over the lens. Those two really come into their own with mixed lighting, e.g. an interior with daylight coming through the windows.

B&H's price was reasonable for this large size and the shipping prompt and efficient.

[0.05 lb] Professional photography usage. Solid and secure when attached. Crystal clear and easy to clean.

[0.05 lb] The use of an 81A warming filter was recommended to me by a pro photographer and this lens by Tiffen did not disappoint. It really enhanced the contrast between a blue sky and the images. With good lighting, the addition of this lens made some of the images appear as though it was 3-D. The lens was clear and crisp. This was a great addition.

[0.05 lb] If you spend thousands of dollars for a camera it makes NO sense to not spend a few extra bucks to protect the lens with a clear filter. Scratch the filter, get a new one. Scratch the lens and get a new one? Ouch. All four of my cameras have this filter. You need this.
