dcains Offline Buy and Sell: On p.1 #6 · HOYA HMC Super vs DMC vs HMC So, do you still use filters? Aug 25, 2008 at 08:50 PM

davwaym Offline Image Upload: On p.1 #8 · HOYA HMC Super vs DMC vs HMC Maybe it is the monitor that I am using...I do see a difference more so in the symbol that shows up on the computer monitor in the comparisons, but I am not sure what I am supposed to be concluding from the comparison. help please.....

Cableaddict Online Image Upload: On p.1 #9 · HOYA HMC Super vs DMC vs HMC Wlachan, The effort is greatly appreciated, but further explanation would sure be helpful. What TYPE of filter? (I asume UV/ Skylight, but you don't say.) What is the first pic showing? A Pentax filter, or the lens used for all four, with NO filter? What are we looking at? (I figured it out, but it's not 100% clear at first.) How about a comparison with a good B&W filter? ------------- Still, this is great stuff. I wish more members posted comparisons like this, instead of just "Hey, look at this, look what I just got ! " type posts. Edited on Aug 26, 2008 at 01:02 AM Aug 26, 2008 at 01:02 AM

It is the reflection of the light bulb off the sensor projected onto onto the filter. That is why it is greenish - the sensor reflects in the green. The effect is worse with different filters.

kenyee Offline Image Upload: Off p.1 #11 · HOYA HMC Super vs DMC vs HMC Interesting that the reflection has the shape of a circle w/ a line through it and a halo. I'd also like to see what a B&W MRC UV filter looks like... Aug 26, 2008 at 02:05 AM

dcains Offline Buy and Sell: On p.1 #13 · HOYA HMC Super vs DMC vs HMC I've owned a few Hoya filters in the past, before I learned not to use filters, and some of the multi-coated ones (I forget the specific designations, but I think I had HMC or S-HMC) weren't coated on the back surface, which you'd almost think would be more important than an anti-reflective coating on the front surface. I replaced them with B+W's MRC filters, but I don't know why, as I still haven't used any of them. Aug 26, 2008 at 12:17 PM

Maybe that's the point, he's showing the higher quality filter still will yield unwanted reflections etc. ....and my point-reason not to use them, regardless of brand. You're adding 2 add'l flat surfaces by threading on a UV and no good can come from that. I understand severe usage protection but randomly slapping one of these on a fresh out of the box lens has it's penalties. Aug 26, 2008 at 12:56 PM

wilt Offline Image Upload: Off p.1 #15 · HOYA HMC Super vs DMC vs HMC Widely known about the quality of filters, and published on the Hoya site...worst among the Hoyas is the Multicoated at 93-94% transmission, next best is HMC at 97% transmission, then SHMC at 99.7% transmission. Less well known is the the 'digital' Pro filter coatings are LESS effective than the SHMC. B+W has 99.6% transmission. Aug 26, 2008 at 11:45 PM

wlachan Offline Image Upload: Off p.1 #16 · HOYA HMC Super vs DMC vs HMC I thought the picture was kind of self-explained so I didn't explain them further (only now I see the typo as the 3rd shot should be "HOYA DMC", not "HMC DMC"). The first shot was w/o filter. The rest 3 are: HOYA HMC SUPER UV(0), HOYA DMC protector & HOYA HMC UV(0). I would like to clarify that these are the only MC from HOYA and they are all MC on both sides. The difference between HMC SUPER & HMC is that their transmission are 99.7% & 97%. The DMC transmission is unknown as it is never made public by HOYA. Just for comparison, Pentax SMC is 99.8%, B+W MRC is 99.6%. Unfortunately I don't have any MRC filters so I cannot compare. However, I believe the practical difference between HMC SUPER and MRC is that the latter is easier to clean. All HOYA MC filters are known to smear easily and difficult to clean using the typical methods. Aug 30, 2008 at 05:29 AM

I have seen information for the Hoya Digital that shows no better transmission than the Hoya HMC, at 97% ! 'For digital' BS marketing at work once again. The new Hoya HD has 99.35% Jul 31, 2009 at 04:09 PM

Reds Offline Image Upload: Off p.1 #19 · HOYA HMC Super vs DMC vs HMC I have tried the cheapest Hoya filters, the DMC, SHMC and SHMC pro 1's. I find the SHMC to provide best bang for buck. As alreasy mentioned, they are easy to clean and offer top transmission and have saved my precious 24L! Aug 04, 2009 at 04:56 PM
