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