B+W 77 mm Polarizing Filter Question

Kim H

:scratch Hi everyone, I'm new to Digital Grin..though I am a member of the Daily Photos community. I am looking at the B+W polarizing filters for a trip to Denver and you (and Sean Sherstone) have convinced me that this brand is excellent. I know it has to be MRC minimum from your threads (thank you for that enlightenment), but now my question is, do I need to get their combo filter kit that has a uv filter with it, or is just the polarizing filter ok to add to my uv filter? My widest lens is the Canon 17-40 so I am assuming that slim is not needed...though the filter on it is a slim...might be helpful with a standard polarizer? Thanks for your help in sorting through all of the information out there...Kim

Hi Kim, welcome to DGrin!

The answer is simple. If you already own a UV Filter and are happy with it
there is no need to buy an expensive 77mm MRC UV filter from B&W. Just
go with the 77mm MRC Polfilter and you will be very happy with it. If you
are shooting with an APS-C camera like the Canon 400D or 30D you don't
need a slim version.

If you want the maximum optical quality you should have one filter
mounted on your lens at a time. Combinding the UV and the Pol will likely
cause vignetting, loss of sharpness and flare in some situations.

I Hope that helped, and that you'll have a good time around here

Thank you so much for your welcome and the valuable information Manfr3d! I AM shooting with the 30D and will certainly remove that UV filter. Interesting that the filter is available with both.. Thanks again for helping me out.:ivar...ps...love the quote!

If you have time to get the filter shipped, look at www.hvstar.com (used to be maxsaver). They have by far the best prices on B+W filters. I got the B+W 77mm KSM MRC CPL from them, only about a $16 difference from the non-KSM version, so why not get the best available? Found here: http://hvstar.net/index.asp?PageAction=VIEWPROD&ProdID=36 Looks like they dropped the price a bit, too! Now only $9 difference.
