Dear all: I was doing a flare comparison for my lenses + filter so I thought of sharing it with the list. I was sitting on the floor, window light at 45 degree left and above. It's about 45 degree on all XYZ axis. This is not a scientific comparison, just what I see through the viewfinder (EOS-30, T-90). First conclusion: at that particular instance, there seem to be not much difference between all filters, or even without filter. The lens itself is all that matter. A rough ranking (and surprising) for MY lenses (some were cleaned for fungus, some with elements replaced) on flare problem at 35, 50 and 70mm, best to worst as follow:
24-85 (!!) 50 1.8 II 17-35 2.8 50 1.4 FD (from this point onwards all are very bad!) 70-210 4 FD 75-300 4-5.6 (cheapo EOS lens, my 2nd EOS lens) 35-70 2.8-3.5 FD 35-80 4-5.6 (cheapo EOS, my 1st EOS lens) 28-80 3.5-5.6 (mkI, very bad, lens coating must be badly damaged during cleaning!) It seems like most of the zoom, if badly flared, will remain the same for all focal length (24-85 and 17-35 are better designed I suppose). Both improved from wide to narrow. I'd say the lenses are unacceptable/unusable from the 50 FD onwards. The lens hood form 17-35 is next to useless. Second finding: I read somewhere Hoya HMC is a very good filter, even better than B+W. Now I can prove that this is just bull... and why B+W costs 2X the HMC. I don't know about the current Super HMC (in the old days isn't it the slim type?), but the normal HMC always shows the green tint. I put 1 each Hoya mono coated, Hoya HMC and B+W MRC on the parquet floor side by side, the result is stunning! The monocoated Hoya is very poor, with strong reflection of the window. Hoya HMC is better, but with the above mentioned green tint. For B+W MRC, it's as if there's no glass there! The parquet is crystal clear. It's really that good (probably because this is a new one). Ok, that's my brief (and I thought surprising) comparison of my lenses/filters to share with. Thanks for your patience to read. regards, Huang Shao Hui __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
