Filter for 21mm asph and for 24mm

[joe_pelizza_salusso_di_vol]

What kind of filter do you use with the 21 and or with the 24? A

normal B+W filter, a Leica filter or a B+W Slim filter?

Thank for your kindly answers

I have a B+W MRC (the only kind of filter I ever use) 010 (UV)in standard mount on my 21ASPH and there's no vignetting.

Most any E55 filter will fit on. On some (B+W) you have to slightly loosen the

filter to get the hood on. I do not use filters myself unless it is for a specific

effect. I have the usual polarising, red and yellow-green filters to hand. I also

have a UV filter if I am going to photographing in a windy and sandy location

or where there is a good deal of salt water spray.

I am using a slim hepiopan es 55 uv sh-pmc filter on my 21 asph. The lens shade can be put on fully. I have tried the non-slim B+W filter but it was too thick for the lens shade to be put in its proper place.

I switched from B+W to Heliopan precisely because all Heliopan filters come in a slim mount.

 

I was not able to mount the hood completely over the B+W filter on my 24 without a struggle. With the Heliopan, no problem.

Ditto! I'm using one of the slim Heliopan filters on my pre-aspheric 21 Elmarit. No sign of vignetting and the hood fits fine. Cheers.
