I've had one of the Hoya ones in 77mm size for a few years and I've found it pretty good. Any filter is going to increase the chance of flare definitely, as John suggests, getting a decent one will reduce this as they're better coated. It's also worth checking if you can still operate the filter ok ...

There will be different opinions on this... I consider 'Digital' filters as simply being a marketing ploy, as I don't see how anything in front of the lens could be digital compatible or not. If anything, digital makes it easier to correct any slight colour casts that a filter may impart, although ...

I've seen some Hoya one's that are multi coated would this also be a good choice instead of going for the Pro versions.

I consider 'Digital' filters as simply being a marketing ploy, as I don't see how anything in front of the lens could be digital compatible or not. I would interpret it as meaning a thin (avoiding vignetting) multicoated circular polariser of high quality. There have been improvements in polarisers ...

I consider 'Digital' filters as simply being a marketing ploy, as I don't see how anything in front of the lens could be digital compatible or not. The term "Digital Filter" means absolutely nothing and is used to 'reel in' those who are convinced that it means something. Digital Filter = ...

I said "thank you, but no, I couldn't possibly inflict such an obvious financial misfortune on such a wonderful establishment as yours". then removed the 'digital' (read plain glass) filter, slammed it onto the counter (breaking the filter), exclaimed "oh dear, the backlight switch on...

The Hoya website proclaims: "Digital Cameras Need Multicoated Filters Digital camera CCD or CMOS sensors are highly susceptible to reflections - this stray light can ruin your photographs! Don't risk your valuable photos by using bare-glass filters." What they're doing is using the ...

Why not contact Hoya, ask them to justify their claims and see what they say? :?:

Tell me, why spend . . . lets say £600.00 on a SMCP-FA 31mm Ltd lens . . . and put £10/£20/£30/£40 worth of cheap glass/plastic in front of it to reduce image quality. Why do it ? I'd agree with you if this thread was about UV filters but it's not, it's about polarizers and I've found them just as ...

That quote should of course have just said 'Mannesty wrote'. I whole-heartedly agree with you as regards which filters are useful and which are not. Dan

This really is a hoary old chestnut of a subject :) . The usual discussion is about circular and linear polarisers and, I think, we are all agreed from empirical evidence that it doesn't matter with Pentax auto focus systems which type we use. My filters, for digital, are now all SMC Pentax ones ap...

Not sure if they still make them, I picked up mine many years ago long before digital SLRs.

and I want an SMC Pentax filter on my SMC Pentax lens! I've only owned one SMC Pentax filter and I must have been unlucky as it developed problems with the coating and therefore hasn't been used since. I wasn't best pleased at the time though as it was a fairly large size (67mm) and therefore not ch...

The idea of describing a filter as "digital" seems to have caused a bit of a stir. I have a Jessops "Digital Pro Filter" (Circulat Polariser) in front of me now, and their rationale is as follows: Digital Multi Coated - greatly reduce lens flare and ghosting caused by reflecti...

I must say the "digital" description doesn't offend me as it does others, I merely take that as an indication that it has had some effort put into the particular needs of digital imaging. It could of course be equally valid on a film camera, but at least the description indicates what it h...

But I fail to see how "Digital Multi Coating" can possibly equate to "the particular needs of digital imaging". I agree it's a moot point and that it can be backwards applied to film cameras as well. The only relevance is that when the lens is open the CCD, being highly refle...

my objection is mainly that I would like them to say what they mean. All of the above listed features are clearly desirable in a high quality filter, whether it's for film, digital or an optical tele/microscope, but as far as I can see none of them is inherently "digital". The term is ...
