Do any of you who have the Canon 50mm f1.8 II lens use it with a circular polarizer at all? often?
And that leads into this question: do all my lenses need a circular polarizer?
Which brand(s) are most effective/trustworthy? I have a Hoya on my 28-135.
What's all the fuss about the Super HMC, ultra thin, blah, blah, blah...is all that extra money really resulting in that much of a better image?
thanks |

It depends on the conditions as to when you need a circular polarizer. Also, to save money, buy the one for the largest lens and then use step-up rings with the other lenses.
Ultra thin filters would be used to reduce vignetting. This can be a concern when filters are stacked.

I plan on solving this issue by going the Cokin P filter route - a circ PL is cheaper for that set up, and can be used on all lenses with adapter rings, under $10 each. Overall much cheaper route.

I recently formulated a similar plan. I currently have three lenses, and they all require different size filters (58mm, 72mm, and 77mm.) A Cokin P system with cover them all for a lot less money than individual glass filters. However, I̢۪m a little worried that the synthetic filters will scratch easily.

I have heard taht may be an issue. i have also heard that the optical quality may be less than glass. Singh Ray makes glass filters, but open the wallet wide!
I have seen $25 P size C-PL, but i have also seen $60 ones. I was leaning toward the high end this time, as I only need one!

Along the same lines, does anybody have a resource that does a good job of explaining different types of filters and applications?
Sure, I could google it but does anybody have a 'learn everything about filters' web page I could check out?
Thanks...

Okay, not bad...
What are some must-have filters for your lenses?

I really want a high quality polarizer, so I was recently considering a Hoya 77mm Super-HMC Circular Polarizer Multi Coated Pro 1 Extra Thin Glass Filter at Adorama for $224.95. If the optical quality is good enough, that $60 one sounds like a steal. Before I buy anything I plan to spend some time looking around for reviews on C-PLs, especially the ones available for the Cokin P system. If I find anything interesting I'll post it here.

Aren't those filters square?

Most of the filters are square, made of resin which attracts dust and scratches. The polarisers are (I think) glass and have a circular mount so they drop into the Cokin filter holder. The Cokin polarisers are much better than the square resin dust magnets.

All autofocus lenses need a circular polarizer. |

Is this still true? I was told this back when I had a point and shoot digital and I've always bought circular polarisers since then but I have to admit I've been wondering whether a digital SLR would have the same problems as the point and shoot.
I was led to believe that polarised light hitting the metering sensors of a digital camera could cause the shot to be metered badly. This kinda makes sense on a camera without a mirror that might meter directly off the CCD. I figured it was something to do with liquid crystal somewhere.
But you're saying it's the autofocus that gets messed up. How does that work then?
