From a quality point of view the best you can get are the B+W circular polarizer filters type "Käsemann" (KSM), with the MRC nano coating. By far best, most neutral color rendition. And no visible sharpness loss.
Polarisationsfilter
Zirkularpolfilter Das Standard-Zirkularpolfilter eignet sich gleichermaßen für Analog- und Digitalkameras. Lineare Polarisierung kann bei Strahlenteilung im Kamerainneren (durch Spiegel oder Prismen) die Belichtungs- oder AF-Messung verfälschen. Zirkulare Polarisierung verhindert das, bei sonst...bw-filtershop.de
There have been several tests in photo magazines in the past confirming that.
Many of the recommendations, the various brands that is, don't indicate whether or not their filters are coated - "multi-coated" - "single-coated' - etc.
Hoya - Kenko - Tiffen - ???
Linear polarizers work fine on all of Minolta's manual-focusing SLR cameras. All you need is a $2 step-up ring.
I own polarizers in the following sizes:
37mm, 39mm (drop-in), 40.5mm, 46mm, 52mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm, and 86mm.
Delamination is a common failure mode. Fortunately, that is easy to see.
You mean years of fingerprints, because of their acidity, eat away at the coating(s)??
'Just found out from their website that Tiffen circular polarizers are not coated at all.
All these years with that Tiffen I wonder how much better my 'chromes might've looked had it been coated (multi?)

If you used a hood, I expect that you would have not seen any difference. Shading the front of you lens is always the best flare reduction technique.
Get a 49-55mm step up ring.
Never thought about step-up rings.
isn't there a question of image degradation due to an increase in 'space' taken up by an 'additional' ring where there'd be the ring from a direct fitting polarizer? (am I making sense?)
There are no problems with using a step-up ring outside of:
1) you need a different lens cap;
2) you need a different lens hood;
3) with some cameras, if you use a fitted case, your case may not fit any longer; and, most importantly
4) in some cases - particularly with some wide angle lenses - hanging the combination of the step-up ring nd the filter out in front of the lens can cause the image to vignette at certain apertures.

I own one size of filters to fit my largest lens. I use step up rings on all my other lenses so I don't have a gazillion extra filters.
That's what I do as well, but it doesn't work for everyone -- see Post #28!!!
