Photo Forum / Digital Photography / Digital Photo / June 2005Hoya polariser question
Having decided on the Canon EOS 20 D and the EF-S 10-22mm wideangle zoom, I'm adding a 77mm circular polariser . Looking at Hoya filters, they offer a 77mm G series Circular polariser at £48.00, a 77mm polariser (with both sides coated) for £70.00 and the 77mm Super Pro 1 ultra-thin one for £157.00 Is it worth the extra price for the dearer polarisers or is the difference in results miniscule? I'm aware the ultra-thin filter will prevent vignetting at max setting on the lens but will I notice a superior result from the costlier filter? Thanks for any advice. John Slevin. John, Keep in mind that a normal lens cap will probably not work on the ultra-thin filter. I have one of these filters and if it's optically better it's offset by the inconvenience of not being able to use a normal lens cap.

So far I've ruined about four Lens Pens on the Hoya grease. A long hard blast of hot water removes enough of the grease to keep it from wicking onto the glass for a while. I tried a normal 77mm Hoya polarizer and it did crop a good chunk of the corners off (and it was badly fogged). I'm using a wide-angle Promaster now. There's no vignetting but it can't be capped. > I tried a normal 77mm Hoya polarizer and it did crop a good chunk of the > corners off (and it was badly fogged).

I, too, am using a Promaster, but according to my local camera shop (and the shipping cartoon it came in), Promaster is made by Hoya. ? -- Slack > > I tried a normal 77mm Hoya polarizer and it did crop a good chunk of the > > corners off (and it was badly fogged).

Compare what happens when you put together the circular (camera) ends of Hoyas and Promasters. Putting together the same build does nothing. Putting together mismatched builds blocks the light. Maybe it's two factories owned by the same company. >> Having decided on the Canon EOS 20 D and the EF-S 10-22mm wideangle zoom, >> I'm adding a 77mm circular polariser .

Stick with German B+W filters and polarizers. You'll be glad you did. Ted Morton |
