    Posted: 12 January 2012 at 06:42
Hi all,

I'm looking for a 77mm CPL for my Zeiss 24-70mm F2.8.
between these 2, which one would you recommend?
- B+W Slim CPL (don't think it's the kaeseman)
- Hoya HRT CPL

The Hoya is slightly cheaper, but the difference aint big. so, cost isnt a factor here. anyone knows the pros & cons? any multi-coatings on those two?

- or should I consider the Nikon CPL II?
the problem is, dunno where to get it here in this region.

Thanks

went to look for the CPL. strangely, the shops here mostly sell only hoya and B+W. I asked for kenko, they said it's not good, quite contrary to the test results on lenstip.com.

any personal opinions??

If you look at the details of the lenstip tests, the Kenko and Hoya both have quite a bit more evident flare than the B+W KSM(So does the second-place Marumi, for that matter). I have had the 72mm KSM slim for quite some time and like it a lot. I picked up a 77mm KSM a couple of years back as new lenses entered the bag -- no regrets. Initially they are a bit snug to turn but over time they smooth right out.

I use B+W CPLs. At times I wonder if I'm crazy, because they cost more than a kit lens. But I've never had reason to doubt their effectiveness, and over the years I've done lots of tests (both on the UV and CPLs) to see if I can detect any loss of definition, or increase in flare, without finding any issues.

I don't use lens caps (too fiddly), so I leave UV filters permanently attached. I don't baby the filters the same way I do the lenses - I just breathe on them and wipe them down - and they still look good after years of use. If and when I replace any of my lenses, I'll transfer the B+W filters to the new lenses, so they are actually the most enduring part of my kit. Money well spent, IMHO.

BTW, I have the 77 slim CPL MRC (not Kasemann) - according to the Schneider catalogue the Kasemann is subjected to more work and QC, but I've been happy with the standard version.

well, in one of the biggest local shops here, the 77mm slim CPL MRC (not kasemann) is out of stock.

the kasemann series was a whooping ~$250 US! never on sale...

but the 77mm non-slim CPL MRC (also not kasemann) is on promo deal for ~$125 US (was ~$190 US).

anyone has tried the non-slim CPL MRC (non kasemann) on ZA 24-70 (on FF)? any vignetting?
I'm thinking of buying this since I think it's a good deal.
though, I don't have FF now, I plan to buy FF in the near future.

I googled and found some say vignetting and some say no vignetting?

PS: I don't plan to stack up filters

B+W Kaesmann slim MRC filters $160-$180 here: BH Photo

I don't have the 24-70 so can't answer that question, but I don't have vignetting issues on the 16-35. Admittedly I don't often use a polarizer at the widest end though.

Hi Dave,

I live in singapore. the delivery cost from BHphoto is ~$50 US
the prices for things like this are slightly more expensive here.

I usually use BHphoto for cost benchmark tho.
so my rule of thumb here, if I can get the same price as BHphoto here, then it's quite a good buy
FYI, the listed price for 77mm non-slim CPL MRC (not kasemann) on that shop is ~$220 US (its tagged). crazily overpriced, eh?
but the sales said, usually he can give ~$190 US price, but now it's on promo for ~$125 US.


so you use the non-slim 77mm KSM MRC on ZA16-35 and A850/900 camera?
and found no vignetting at 16mm?? that's encouraging

No, it's the slim. Most often when using this lens with a polarizer I'm a bit longer than 16mm to avoid variations across the sky.

To be clear, it's not that I've tested carefully and found no vignetting, more like I just haven't noticed any issues in my shooting.

I use the slim non-Kasemann MRC CPL on my 24-70. I also use a regular (non-slim) B+W UV filter, but not at the same time. In neither case do I have issues with vignetting showing up after I've run the lens profile in LR3. I suspect the depth of the ring for the non-slim CPL is similar to the non-slim UV, so I'd be surprised if you see any additional vignetting.

The only reason I can think of to go for the slim version is if you think you may get a wider lens with a 77mm thread, like the CZ 16-35, in future.

your point taken. I actually thought of this too. but then again, at 16mm FF, maybe it's not a good idea to use CPL. or so from what I've read.

I think I'll just focus the CPL usage on my CZ 24-70, for FF usage. I'm still using A700, but I'd give my next purchase priority to FF camera over CZ 16-35

just found out from the web, the B+W UV F-Pro is 5mm, but the CPL is 7mm.
hmm...

and I already bought the B+W CPL MRC F-Pro... oh well, I can definitely enjoy this with my A700. when FF comes, that is hopefully the same story.

Mmm, i wonder if the additional 2mm will make a difference. Probably marginal. Maybe I'll try stacking my CPL on top of the UV and see what happens.

As for CPL on an ultrawide - the reason some people advise against it is that you get an inconsistent effect across the frame. Polarizers have the greatest effect when the sun is at right angles to your subject, while the effect is negligible when the sun is behind you, or your subject is back-lit. With an utrawide, you can get all of this happening in one shot, so skies can look a little unnatural, for example. However, I quite like it - for certain subjects, like architecture (reducing reflections on glass). I definitely wouldn't write off your CPL on a 16-35.

Anyway, this is prolly academic, because you've bought the F-Pro. I don't think you'll be unhappy with it.
