are filters that different?

Is there a huge difference between the Hoya super HMC circular polarizer and the pro1?I am going to buy one soon but I dont know if the extra cost is justifiable.

it looks like the pro 1 has a little more attention to it to ensure lack of reflections and flare when in use. they also advertise super-multi coated, probably just to say that more attention is given to the coatings to help ensure greatest light transmission and not tinting the light (ie it's more neutral). plus it looks like it has threads on the outside of it allowing you to add another filter on top of it?

these are good things in general when it comes to optics. i can definitely see that the extra attention to detail is worth the extra price.

i've never used either of these and personally bought a pro-master CP on impulse at a local camera shop one day. the pro-master certainly isn't bad but i'm sure it's not the best out there. i'm not aware of any special things about my promaster except that it is the multi-coated one.

i'm sure that there are differences in final image quality when it comes down to it otherwise it'd be a total waste to have two different products and it's always good to get your capture as good as you can.

The bad effect in the background of this pic is due to a cheap filter.

The Pro1's have the SHMC coatings which are better than the HMC plus a few other advantages, I would say it is well worth getting the best you can. I use Hoya SHMC Pro1 myself.

Check the reflectance of the various type and other features here

Lester,

I have the same Hoya SHMC Pro1 filter myself. Recently I took some shots with the filter on my 10-22 (with the hood) and got this ugly flare in the resulting images. Have you also experienced flare with yours?

Hi Sys

Why don’t you put up an example of the problem you had?

I do test for flare including a comparative with and without filter. One can't be completely comprehensive, but in general the filter is a second order effect with the dominant flare being due to the lens but the filter adding some second order highlights (in fact these could be due to some muck on the filter).

The test conditions are generally slightly worse than real life sun in the frame. I can’t say I have noticed anything in real life shooting.

Go to the first link for the test description and the second for the 10-22mm.

I posted the image with the flare about four days ago here:

https://photography-on-the.net/forum/showthre​ad.php?t=274954

The thing that several of us forum members are wondering about -- in another thread topic -- is whether the Hoya we've gotten from Hong Kong at nearly half the price here in the state, is genuine or a fake, but there are no optics experts here to be able to determine the real filter quality vs. fake. So when I got the above flare in my image, I started wondering....

By the way, I saw the tests from your links, and I'm quite surprised that filter actually creates worse flares??

I either missed that or was too apathetic that day.
I'll reply in that thread.

I am always careful to get equipment for authorised dealers in the UK (where I am). One does hear things about stuff from HK and Singapore how much of an issue it is I don't know.

Not sure what you are saying. You are surprised the filter is adding some flare?

Yes it will, but it is less than the lens, there is more of it. As I say this might be partly due to dirt (shame on me).

The 10-22 seems to be quite good for flare, not as good as the 17-40 but a hell of a lot better than the 24-105.

The test setup is about two stops worse than the sun however in relative luminance so the issues are exagerated.

Well the difference is about $50.From what I can tell they both have the same shmc coatings but the pro-1 has the knurled frame,and a few other physical differences such as materials used.I think im gonna try the shmc for now,this is my first high quality filter and I think it will suit my puposes.

Is it front threaded like the Pro1?

I would always advise to get the best filters you can, and the Pro-1D filters from Hoya are the best they make.

BTW I am a fully UV filter kind of guy, and on several occasions have been very thanful that my lenses have been protected in this way.

The best filters are German made, Heliopan and B+W. Check if they fit in your price range.

Yes they are both SHMC which seems to be the lowest reflectance coating available, Hoya list a few Pro 1 specifics here http://www.thkphoto.co​m/digital/dp-02.html, I am not sure if some or none apply to the old SHMC grade or if they are still made.

My supply used to send SHMC but now sends Pro 1.

is there really any difference between a PRO 1 and a PRO 1 Digital?

I suspect not...

Edit:

But this from their Brochure http://www.hoya-online.co.uk/Hoya.pdf

"PRO 1 FILTERS
New technology has enabled HOYA to produce superior performance
Skylight and UV glass is just 1mm in thickness, which is tempered for
increased strength. The glass is mounted in a super slim 3mm ring
(with front filter thread), which avoids vignetting and results in a 40%
weight saving over standard models. Twelve layers of super
multicoating are applied to the surfaces to produce an average light
transmission of 99.7%!

PRO 1 DIGITAL FILTERS
Newly formulated multi-coating for digital camera CCD or CMOS
sensor. These image capture devices are highly susceptible to
reflections - this stray light can ruin your photographs! Don't risk your
valuable photos by using bare-glass filters."

So they seem to consider them seperate lines, but don't realy say what is different.
