scott kirkpatrick Posted September 16, 2017 Share #1 Posted September 16, 2017 Advertisement (gone after registration) I haven't used polarizers, but was intrigued with Roger Cicala's recent article: https://www.lensrentals.com/blog/2017/09/my-not-nearly-complete-but-rather-entertaining-circular-polarizer-filter-article/ which offered to sort out the subject once and for all, with his newly purchased green laser, spectrometer, and optical bench. Read to the end for his startling conclusion -- they all do almost everything that they promise to do! Who uses these on the SL? scott Link to post Share on other sites More sharing options...

FlashGordonPhotography Posted September 16, 2017 Share #2 Posted September 16, 2017 I have drawers full of polarisers and other filters. However now I just have a set of Lee filters and adaptor rings for every lens I own. That way I only need one set of selected filters. You can't replicate what a polariser can do in post so they are, IMHO, one of the few essential filters to own. Gordon Link to post Share on other sites More sharing options...

ramarren Posted September 16, 2017 Share #4 Posted September 16, 2017 Who didn't know this already? Good article but rather obvious. The two filters I always buy for my lenses are a polarizer and a six-stop ND filter. The third filter I sometimes buy is an IR pass filter. The fourth filter I buy only rarely is a soft focus filter. I almost never buy 'effects' filters. You cannot replicate the effects of a polarizer, ND filter, or IR-pass filter in software. You have to filter the light. Anything else is at least partially replicable in image processing. Link to post Share on other sites More sharing options...
jplomley Posted September 16, 2017 Share #5 Posted September 16, 2017 Any consensus on best brand? I've ever only bought the Heliopan SH-PMC filters and have never had a problem. Solid brass mount, smooth rotation and easy to clean. But $$$. Are there equal or better alternatives? Link to post Share on other sites More sharing options...
antigallican Posted September 17, 2017 Share #6 Posted September 17, 2017 I used to get a lot of effect out of linear polarisers and film. I can't see much effect off circular polarisers and digital. I have a Hoya 82mm circular which I put on the 24-90 sometimes but I'm damned if I can see any difference and I certainly never see that sharp pola effect you used to get turning a linear polariser. I'd love to be proved wrong or be shown my error. Link to post Share on other sites More sharing options...
jrp Posted September 17, 2017 Share #7 Posted September 17, 2017 Advertisement (gone after registration) The article shows clearly that the polarisers have different transmission characteristics and prices. Beyond that, the newer filters are easier to clean. Link to post Share on other sites More sharing options...
LeicaR10 Posted September 17, 2017 Share #8 Posted September 17, 2017 Jplomley, I have used most major brands of polarizers over the years and neutral density filters as well. But I found the ones made by Breakthrough Photography to be by far the best color neutral polarizers and Neutral Density filters out there. Here is the link to check them out. https://breakthrough.photography Most recently, they came out with a far better 100mm holder too. I think you find them to be most excellent, plus if you don't like them, you can return them for any reason within the first 300 days. Hope this helps. r/ Mark Link to post Share on other sites More sharing options...
farnz Posted September 17, 2017 Share #9 Posted September 17, 2017 While I'm sure the quality is very good, regrettably the Breakthrough Photography CPL polarising filters start at 46 mm so if you have one of the many Leica E39 lenses you'll be out of luck unless you're prepared to mess about with step-up rings.
