Magic CPL or not?

Hi all

Can anyone shed some light as to whether the price of the B+W 77mm kaesemann MRC SLIM Circular Polarizer Filter is justified?

I am considering this package after I learned of this retailer:
http://hvstar.net/index.asp?PageAction= ... ProdID=320

It is an expensive CPL but I am wondering if there is some magic there or not. I understand that there is good (German?) glass there. This will be used on a canon 24-70L until I have more juicy 77 sized threads to place it on (hopefully sooner than later).

Thanks, Dan

I believe that the good quality CPL will polarize a bit more, but most importantly, it does not have any colour shifts or ghosting effects that can be caused in lower quality ones.

The Kaesemann is a nice solid filter. I use the 77mm B+W but not the slim filter. Its about $30 cheaper and I didn't need the slim. They are glass and brass construction and are supposed to stand up to heat, dust, moisture and abuse better.

I use the B-W UV filters and I am very happy with these.

Happy new Year,

Thanks guys. I like the idea of withstanding abuse, not that I am abusive. I've experienced numerous suicidal hoya CPLs that magically fly apart when you adjust them. I always get greasy paw prints on everything once they are re-assembled.

Yes that is very true, being there, done that... :(

As a further insult from hoya, once I went into FotoReisel to get one because I needed it then and there. And the guy went though about 10 that were loose and defective before giving me a reasonable one (reasonable means lasted about a month before springing apart).

When you put em on then you can get em off again. Some filters seem to weld themselves to your lens and you need a claw hammer to get them off again.

Dan,

unless you go with an ultra wide lens, using the slim version won't do anything for you on most lenses.

I have the one you link to above and for my Tokina 12-24, I don't get any vignetting with the slim CPL. My old regular Hoya was causing vignetting on the 12-24.

HTH,

André

Thanks Andre, the slim factor is not so much where I was angling my Q. I am considering getting either a sigma 14 2.8 as an intermediate wide lens or a 14-24 Nikkor if there is an available adaptor. Neither lens support a front filter. If I can get a better price on the non-slim I will do that, I gather it means I can use a standard 'pinch' cap too.

That is pretty well what I had to do to get the Hoya off :shock: :evil:
