ND filter for Voigtlander 15mm f4.5 Heliar II M mount

[PaleBlueDotCitizen]

Does anyone know if special "wide-angle" filters are needed to prevent vignetting when used with the CV 15/4.5 Heliar II? I was just about to pull the trigger on a B+W ND filter from B&H when I notice they also have "Extra Wide Glass" versions with oversized metal rings.

The wide versions are out of stock with 6-8 week estimated delivery. I leave for Italy in 2 weeks!

I'll be using it with an APS-C camera (Ricoh GXR) but it is important to me that it will work without vignetting on a FF sensor camera (roll on M10)!

Anyone have this lens and experience with filters on an M9?

Thanks!

I don't believe the xtra wide filter will clear the fixed hood but I could be wrong. The hood is fixed right?
You might be better off trying to screw on a step up ring to see if you have the clearance inside the hood and use a larger filter.
It'll save you a few bucks as well.

Yes the hood is fixed. Well, the lens accepts 52mm filters and is designed to be used on a film rangefinder so I assume there won't be any vignetting. I have neither a 52mm filter or a film (or FF) rangefinder here to verify that. I think I'll just order the regular filter anyway. Cheers Tony!
