Multi-Coated vs. Single-Coated Test Results
Here's my side-by-side comparisons of the 62mm Tiffen non-coated UV filter, $14.95 against the 62mm Nikon L37C multi-coated UV filter, $33.95. All tests were conducted on a N80, Nikon 70-300ED f/4-5.6D lens at 70mm, with tripod, no-hood.
Test 1: I shot a picture of the blue sky with enough angle to start to get a little flare. As you can see, the Nikon (pic. 1) keeps the flare relatively well controlled, but the Tiffen (pic. 2) fails miserably. Both were shot at f/13, 1/750, Kodak Supra 400.
Test 2: I shot a picture of Pac Bell park, and you can notice that the Tiffen (pic. 2) has a problem with the reflection coming from the metallic seats in the lower left corner of the frame. Flare again. The Nikon (pic. 1) doesn't really. Both were shot at f/11, 1/90 sec, Fuji Reala 100.
Test 3: I shot a picture in a room with various items and a small amount of light. When metering A-mode at f/32, the Tiffen (pic. 2) showed a solid 4 seconds, but the Nikon (pic. 1) wavered between 3 and 4 seconds, showing that it was allowing in more light. Notice that the first (Nikon) image has deeper shadows and fuller colors. Both were shot at f/32, 3 seconds, Fuji Reala 100.
That's all. Let me know if you've got any questions or need any other data!

Thanks for doing the footwork on putting images to this age-old debate. At least on these web images I don't see any significant difference between the two lower shots, but the direct sun flare/reflection in the top image is evidence enough for me to stick with mulitcoated filters.
I can see shadow difference (assuming the scans are accurate to the film), but I don't see the seat reflection issue you mention. As to the shadow lightness with the cheaper filter, Tiffen actually makes a special filter that exaggerates this effect to reduce image contrast (brilliant turn of a problem into a marketable feature, don't you think?):
Now the question is, does a premium filter like a Nikon or B+W have any practical advantage over a moderately priced multicoated filter from Hoya? My experience says no, but I haven't put this to the side-by-side acid test with example images...
Thanks for the interesting post!

Great comparisons... I have been looking for something like this for quite some time.. Thanks for the time and effort!
I agree with BJ on expanding the comparisons a bit. I would like to see how the Nikon fares against the SHMC Hoya UV filters as well.
In addition, I think another good comparison could be between some single coated filters, vs. multicoated. The Tiffens (from what I understand) are completely uncoated. Hoya I know makes a few grades of filters, the standard Single coated, Multi Coated (HMC) and Super Multicoated (SHMC).
Judging by pic #1, I'm glad I got the SHMC filters, however it would be interesting to see if there is little to no difference between a Single coated and a Multi coated. I can see there is a vast difference between Non-Coated and Multi-Coated, but I am curious to know if additional coatings above single coated, are really nescessary.
Thanks again! I will have to show this to a few of my friends that do not buy into spending the extra on MultiCoated filters.

I have one more lense to go before I have replaced all my Tiffen/Crystal Optics filters with Nikon LC37 UVs. I was able to tell the difference even without side by side comparisons because I often don't put my hoods on as I should and flare is often been a problem...esp with my 24. Your shots show an evident difference...maybe my monitor is better as I see the issues you raise with the Tiffen filter on all 3 pictures. I also love the way the Nikon filters go on and off ...not like the Tiffens as I frequently take the UV of my lenses when using a CPL filter.

Thanks for the visuals. I am really surprised at the difference I see in the first setting. I cannot see a difference in the 2nd two settings in the scans, but with jpgs I am not surprised. It is a good reminder to me to be aware of flare with cheap UV filters.
I would like to see different brands of multcoated compared also. Please, if you try that post them too.
