I shot a wedding with a $12 Tiffen filter and the loss of contrast was upsetting and extreme. I used this filter.

I learned the hard way. :-(

Can anyone post a link to the BH website of a filter that doesn't lose contrast? I see the B&W filters are recommended but they are not multi-coated at least I don't think they are and I hear this matters.

Is this a good filter? http://www.bhphotovideo.com/bnh/cont...goryNavigation

B+W are multi-coated. Expect to pay a fair amount for a good filter. Beyond $50 IIRC. The $12 price is a good tip-off that you didn't get much. In fact, I'd bet the 'glass' in that filter isn't at all clear either.

Call B&H and have a chat with them about this.

For a PD-170, I was thinking of buying a Polarizer filter from tiffen, will they just screw on, or do I need to purchase somthing else like a mount or adaptor ring?

Thanks

I have a filter B& H sold me when purchasing the camera too. I noticed dancing green fireflys on pinpoint lights (i.e.. candles or chandeliers) and a reflection of the lens on outdoor shots.

When I am shooting in a controlled setting (most of the time) I'll leave the Filter off.

The dancing is caused by the OIS. The OIS is a major contributor to pin-point light reflections in the lens system. Turning it off at least insures that the fireflys don't dance.

And Simon - if you do get a polarisor, do make sure it's a multicoated one. Remember that with it on (and usually in good strong sunlight) this sandwich of glass forms your new front element.

Thanks Guys, Is there a big difference between a Polarizer and Warm Polarizer?
What would I miss out on if I dont get the Warm version?

Thanks

I'd leave all warming to post, that way it's easier to backtrack.
