Using a circular polorizer on a HM700U Any issues? at DVinfo.net

Hi all,

Just purchased a B+W 72mm Kaeseman Circular Polarizing Multi-Resistant Coating (MRC) Glass Filter (Slim) for my 700 from B&H. And before I start using it I'm wondering has anyone else used a screw on cir pol on their 700? Is there anything adverse I should know about...Pros...Cons... I shoot manual almost 100% of the time. I understand I could have gotten a Linear pol, but from what I've heard they block metering if that is in fact correct. In any case I would still want the meter to at least function. I would be using it on top of an existing B&W UV already on the cam. FYI, I have the 14X Canon Lens on mine.

Anyone???

Thanks in Advance...

I have a tiffen circular polariser and all though I haven't used it much the images look good. I was in the Rockies shooting lakes and needed to cut the glare down. I like that you can spin it to get the desired effect you need. I also attached it to a UV filter. Hope this helps

Thanks Calvin,

I received mine yesterday and had it out mid-day just to see how it would perform and if there were any interactions with the Cam and I saw none. As a matter of fact it worked pretty good. I would recommend anyone who goes this way make sure they get the thin/slim version as the 14X Canon lens at full wide tends to vignette with stacked filters.

I was able to keep my B&W UV and place the thin CP right on it and even fit with the standard hood, was still able to rotate the CP without a problem. I tried in several different combinations ND1 & CP good combo, ND2 & CP too much, CP only was real good. Could in some cases be used almost regularly.

I was curious to see how the effect worked during panning and was very good as expected with the sun directly behind me. Even held 60-90 degrees left and right of primary center before I had to make a minor rotational change.

I thought the drop in f/ stop penalty would be higher than it was, but no worse than using ND2.

I'm gad I went for the B&W Kas CP as it should hold up in an industrial setting, and the varying weather conditions we have here in the Northeast as it is a sealed version.

Thanks again for your observation...

Have a happy holiday...
