Circular polarizer for the 16-35
« on: February 25, 2013, 09:06:41 PM »
I'm looking to purchase a B+W circular polarizer for my new 16-35 lens. Does anyone know if this particular one shows vignetting at the wide end?

http://www.bhphotovideo.com/c/product/10890-REG/B_W_66_016117_82mm_Kaeseman_Circular_Polarizing.html

Also, how bad is the banding? Is it better not to use one, or do the benefits outweigh the banding problems?

Thanks!

That one (standard mount for CPL, which is ~7mm thick) will cause a slight increase in optical vignetting (<1 stop wide open).  You'd be better off with the Slim or XS-Pro mount. 

There will be banding on blue skies at wider than 24mm (assuming you're using it on a FF camera), but it's great for waterfalls, increasing saturation in foliage shots, etc.

I've got it, do you want to buy it?

Thanks neuro.

Yes, I'd be using it on a full-frame camera (forgot to mention). I was trying to avoid the slim mount because of the flimsy filter cover. I have already used one of those on a 10-22 in the past and was not particularly fond of it. Does the XS-Pro mount have filter threads that would accommodate a lens cap?

I mostly bought the 16-35 for low light situations - indoor and out, so I'm thinking about forgoing a polarizer for that lens altogether. (Man they're expensive!) I also have the 17-40, and have the corresponding 77mm polarizer, so for landscapes, I may continue to use that lens where f4 is generally fine.

At some point, I'll get the 24-70 II, so I'll have to revisit the 82mm polarizer again.

Thanks!

Yes, the XS-Pro has front threads.  I have the Slim, I don't use the cap but then I only put the CPL on during active use, and take it off before putting the lens away.  I normally keep an XS-Pro MRC UV filter on it (needed to complete the weather/dust seal).

Thanks again neuro. I thought about that as well, i.e. not really needing a cap for the CPL since it wouldn't be on all the time. Still, it would be a nice option to have as I can see myself carrying around that configuration for several hours at a time.

I just placed an order for the XS-Pro MRC UV filter. Thanks.
