I need to buy a 77mm filter and after deciding that I want a hoya Pro1 I then found out that there are two different types...


Hoya 77mm Digital Multi-Coated (DMC) Pro1 UV Filter


Hoya 77mm Super HMC Pro 1 UV (O) Filter

Price for both is identical, the first one says digital multi coated but the second one is HMC which I presume means H(something??) Multi-Coated too? So whats the difference between these, and does the digital one really make a difference or is it just hype?

Hoya web site no help at all.....

I think it's designed to reduce ghosting etc that you get from the sun on digital sensors.

[Steve]

Which is, the D version? And where did you get the information?

[JMitchell]

Sorry yes the D one, and I believe I asked the same question somewhere, or to someone a while ago, or read it on some website (not the hoya one I don't think)
Don't you trust me Steve?

At work (and I also apply this all of the time now) I've always used the ABC system.

A - B - C

Assume nothing.

Believe no-one.

Check everything.

HMC stands for Hoya Multi Coated
SHMC stands for Super Hoya Multi Coated. This one does not have the front female thread. So you can only "clip" things on the front on the filter.No good if you have the Canon hood or another filter.

And yes "D" is the digital filter.and is 3mm thick which may help reduce vignetting when using extra wide angle lens.
I hope this helps Brian.

Thanks for the reply Jack.
I research everything I buy with my own money, there is no offence meant but I like to know what I am getting for my hard earned. There is nothing worse than an uninformed and bad purchase that could have been avoided with just a little research

If you wish to buy it for me to try then I will totally 100% trust you, no questions asked.

Great info Brian. So since it's going on a wide lens and I wish to avoid possible vignetting plus I would like to clip on my lens cap when its not being used...which should I get

[Dabhand16]

I don't have any Hoya filters, but my lens caps that grip inside the filter threads can be fitted to mine with no problem. It is the lens hoods that can have problems as they can't be locked on unless they can fit over the filter and still reach the bayonet fittings on the lens.

Steve try these sites.
Hoya Filters Information Page.

Hoya Camera Filters. Hoya Pro 1 digital filters at photofilter.com

I think it has the answer to that and more.

HIH,

Cheers for the links...off to look.

Dabs I had a very thin hoya filter (Probably a Pro1 but I can't be sure) a few years ago and it definitely didn't allow the lens cap to clip on. In the end I had to buy a slot over type soft plastic cap that was a right royal pain. I really don't want to end up in that situation again but would like to avoid vignetting too.
