Since one ideally uses a polarizer at a right angle to the sun, I have
never been certain that adding coating to a polarizer accomplishes very
much. I believe that Pentax does not add SMC coating to their
polarizers, while they add SMC coating to nearly everything else that
light goes through.
The purpose to applying an antireflection coating has nothing at all
to do with the effects of a polarizing grid on light passing through
it. Antireflection coatings reduce scatter at the air-glass
interface, which causes flare. This is just as much a problem with a
polarizing filter's
Hello!
I have a few questions about Multi-Coated circular polarizers.
I am considering buying one for my SMCP F-70-210/4-5.6, FA 50/1.4
and future D-FA100/2.8.
For other lenses I am using BW 77E slim c-polarizer which works fine
on my both Tokinas. The only problem I have with it is that it is
Don't get the slim version, get the standard. Slim versions of
filters generally dispense with most if not all of the front mounted
threads to help prevent vignetting with short focal length lenses,
which isn't a problem with portrait to tele lenses.

Yep. It is exactly why I bought the slim version: so that I can use
it on Tokina 19-35 (yet with the film camera).
It might have been an overkill, - but I definitely had no vignetting.
:-)
I am not looking for a slim version in this case: all the focal lengths
are =50mm.
Any recommendations on
B+W makes the best polarizers, and their mounts, MRC coatings are
state of the art.
I wouldn't consider anything else.

So, do you have any recommendations for a good quality polarizer that
is not too expensive? Or even better - can you compare or point
to a web-site that has comparison of different polarizer brands?
If you have one that you've been considering to
