Polarised filters
with a linear filter the camera changed the shutterspeed at around 1 stop when set to Av while turning, with circular filter it doesn't change at all. Well, well... you learn something new every day. All this time I've thought that the exposure is supposed to change as you rotate the filter. N...

Polarised filters
Something else I just noticed... Point a polariser at your computer screen (assuming it's an LCD monitor, and if it's a CP, ensure that you look through it in the same direction as the camera would). Rotate the filter. The screen goes almost completely black. I never knew that the light ...

Polarised filters
Thanks for the advice, and for the link, ChrisA. I now have a K-X with a couple of zooms. I used to keep a simple and cheap UV filter on all my lenses to protect the front element from damage, dirt, fingers etc. I reckon a polariser (although not quite as cheap) will do the same but also cut down...

Polarised filters
Like Chris A I've been using linear pols, and I always put their effect on exposure to the reduction of glare from reflective surfaces and darkening of the sky as you turn the filter! Even so, I haven't had any problems in practice, so i'll continue using one. And I still think its misleading to say...

Weather seals
There are a number of threads where the weather sealing is mentioned. The last one being the "dodgy" non sealed K7 grip. If its sealed, fine. If not why is it an issue? Anyone lost a winder or drive or camera or lens due to moisture ingress? If so, how bad were the conditions. My Sigma 70-200E...

Marumi DHG circular polariser
'lo All Just wondering if anyone has a Marumi DHG circular polariser. I understand these represent pretty good value for money: http://lenstip.com/115.4-article-Polarizing_filters_test_Results_and_summary.html Currently I have a linear polariser which works reasonably well. Now, I don't w...

Marumi DHG circular polariser
The main reason I am considering getting a circular polariser is to use it alongside the linear polariser as a variable ND. I've not tried it out but apparently if you mount a linear polariser on top of a circular polariser you can vary the amount of light you let through. The Marumi is relatively...

Marumi DHG circular polariser
Well my Marumi filter turned up. Haven't had much chance to use it yet but it seems a solid piece of kit and nice and slim. It does indeed have a thread at the front for affixing another filter so I was all go to try out the variable ND effect... ... but nothing happened. The image went from...

Free Raw software
I find Helicon Filter a nice package, currently HeliconSoft are offering version 4.93.2 of their package as a free download no strings attached (fully functioning). You can also try a the Beta release of their new version 5 package, both include a RAW converter :)

Ultrawides and grad filters
with a 77mm adapter, 10mm does not appear to vignette at all with the wide adapater. Only one filter, though.... Bret

Ultrawides and grad filters
I use Cokin P series with my 16-55 which is also 77mm filter size but i do experience vignetting at around 18mm, I`m surprised to hear that a 10mm does not. Mystifying! Regards - Pete

Ultrawides and grad filters
If you still have problems after ordering the Cokin, I don't know if this will solve the problem but it may. I use a Lee wide angle filter adaptor ring and have had no problems with it at all. My wife Fran used to use the normal Lee adaptor ring and at 18mm and she had a few vignette problems and so...

CS5 is here
Well, with a quick 30 minute test drive.. - Content Aware Fill .. AWESOME in demos. (Honestly, it didn't look that great in the demos either if you really looked at what it was doing... often a good start, but not *great*) I took a portrait. Head shot with a somewhat plain black/grey background....

circular polarizer multi-coated glass or not?
B&W is certainly a quality brand. The coating prevents reflections, and is water repellant. Any high quality filter manufacturer will add a good coating, multi or not. I would never put more than one filter in front of the lens. The more glass the more trouble.

Thank you, what about if I just used the polarizer, and also an ND grad filter in front, would that make a difference to the photo as well. Thanks again susan
