Hoya so expensive because............

Ok well I'm looking for a nice 82mm CPL to slap on my 16-35 MK II. The 3 obvious filter companies all have really different price ranges for what they all claim to be the same thing.

Super multicoated 82mm slim filters are:

Hoya: 320
B+W: 200
Heliopan: 167

Why is there such a price difference?

Quality.

Kind of like Canon vs Sigma.

I find it a bit ironic that you have a $2800 camera body (on order) but are questioning the cost of a filter.

Once you make a huge purchase like that you start to think about the small things.

Any difference between the multicoated b+w filter and the kaesman b+W filter?

I use Hoya SHMC Pro1 myself and yes good quality filters are expensive but I am surprised B+W and Heliopan are this much cheaper.

All three makes have two or more grades of filters, roughly equivalent types are:

Hoya SHMC or Pro1
B+W MRC
Heliopan SH-PMC

The B+W and Heliopan's without those letters are single coat filters and should be avoided.

AFAIK the kaesman has sealed edges (polarisers have a polarising film between two sheets of optical glass).

May be worth paying for if you spend a lot of time in humid conditions. However, if you are in such conditions you should be keeping your kit in a dry box when not in use to stop fungi growing on the lenses etc.

B+W. I seem to killpolarizers fast and they have the best quality. They don't deleminate. My hoya is delaminating and my last hoya went cloudy. If this is indicative of their entire range, I'd not buy hoya again.

For what I know, who knows! Pretty sure that the kaesman will provide you the finishing touches on weather sealing an EOS 1 package.

God what do you do to them?

I have a 25 year old hoya polariser and it is just fine.

The B+W kaesman will be better for you, I can only assume you are using the filter in damp conditions or something.

I think it is a bit unfair to say this effects the whole of Hoya's range, only the polariser are laminated, all the others are solid hoya optical glass.

boats, sand, sun, surf, heat, cold. The usual. I have a number of polarizers and the ones that needed replacing were the Hoyas. My other ones are fine.

Not sure why. But yes the other filters are solid glass, I was just commenting on the possibility of this quality issue affecting other Hoya manufacturing processes. It's pretty hard to screw up a piece of threaded glass.

Thermal cycling could cause issues with any laminated structure in the end.

Is it the B+W kaesman you are using or just the bog standard B+W polariser?

I would not expect the standard B+W to be any better than the Hoya for sealing unless there is some process issue in the manufacture.

B+W Slim. Not the kaesemann.

Odd, what grade of Hoya BTW?

With the 35L you'll save money at least. It's only 72mm.
