Anyone tried this filter b4?
But, thinking on how to keep it clean, I prefer B+W UV MRC filter.
:dunno: lost.. what have IR got to do with all these when TS is asking about hoya Pro1 Digital UV filter... :dunno:They just add another layer (or few) of coating to filter InfraRed IIRC. InfraRed light is bad for digital sensor than UltraViolet light. Why don't they just use InfraRed filter and remove UltraViolet filter if like that? Errr..., maybe because they also want this product to be used on film camera too :embrass: ? And the price of 2 filters is higher than price of one filter :think: .

Because the filter ts mentioned is digital pro series, which I believe is capable to filter InfraRed light. As I mentioned before, InfraRed light is bad for digital sensor than UltraViolet light.:dunno: lost.. what have IR got to do with all these when TS is asking about hoya Pro1 Digital UV filter... :dunno:
anyway the best filter I used gotta be marumi... cheap and "superbly" good...
not sure, but iirc pro1-series digital series is practically no different from HMC other than a extra coating mean for digital, just like tamron Di and Sigma DG. at probably slimmer profile than normal HMC. :dunno:Because the filter ts mentioned is digital pro series, which I believe is capable to filter InfraRed light.

Its different coating for filter and lens if stated for digital series.not sure, but iirc pro1-series digital series is practically no different from HMC other than a extra coating mean for digital, just like tamron Di and Sigma DG. at probably slimmer profile than normal HMC. :dunno:
dono... but from hoya website, they didn't even mention anything about IR... :bsmilie:Its different coating for filter and lens if stated for digital series.
Filter for digital series have extra coating to filter out InfraRed light.
Digital series lens have a coating to prevent reflection because of digital sensor. This nothing to do with filtering InfraRed light.
Bear in mind, the digital sensor itself have a coating to filter out InfraRed light.

Yah..., maybe because they think people know if they put infrared filter, people will said it is a marketing trick :bsmilie: .dono... but from hoya website, they didn't even mention anything about IR... :bsmilie:

Exactly. That's why sometimes IR photography do the modification by removing THAT filter on top of sensor.Hmm.. isn't the InfraRed Filter already built-in on DSLRs? This was what I read in the books on Digital Photography...

Maybe they want to give impression to people that double filtering is better than single filtering?
For me, its a marketing gimmick.

There are 2 types of filter. IR block filter, and IR pass filter. I believe the filter to put on front of lens for IR photography is IR pass filter.The IR filter you attach over the lens allows only IR radiation in. The one on the hot glass over the sensor tries to block ALL IR radiation, but doesn't. The reason such a long exposure time is needed when you don't remove the hot glass filter is because it's preventing most of the IR radiation from hitting the sensor. Removing the filter and putting in place a filter that allows ONLY the IR radiation in allows you to look through the viewfinder (since you don't need the over-lens filter anymore) and also a quick exposure.
is there really a need for such thin UV filter? most lenses I know do not vignette unless you stack more than 1...any one use Hoya Pro1 Digital UV slim Filter? heard it it is very thin and has thread in front.
is it easy to clean?
I have to give up B+W as the slim version has no thread and i cannot mount my filter system.
