UV or Skylight filter for 40mm MF wide andgle lens?

Hi, I have Zenzanon PS 4/40mm wide angle lens in my 6x6 bronica. The

lens have 95mm filter thread size.

<p>I am looking for field experiences from similar wide angle lens

users (zenzanon PS 40mm, Distagon 40mm). Which filter is best? B+W,

Heliopan, Hoya? The filter should not be flare sensitive. The lens

itself is already (too much?) sensitive for flaring..

<p>My aim is to keep filter always in the lens. Otherwise the front

element of the lens is too vulnerable.

<p>Regards,

Jukka,

FWIW, I usually keep a UV filter on the front of my lenses... whether it's UV or Skylight it

doesn't matter too, too much. Some people like the Skylight because it "theoretically"

warms up the image a tad bit.

As for the manufacturer... both B+W and Heliopan make first rate filters. I've not used

Hoya all that much so I won't comment on them.

Cheers

<p>Thanks.

<p>After checking prices and filter availability, I ended to B+W filter. Expensive, but has so good reputation and should not cause any vignetting because filter is quite thin. Even if it's not slim model.
