Hi, I'm looking to buy an optical viewfinder for my GF1. Will a 40mm Voigtlander cover the area of the 20mm, or do I need the 21mm? I was thinking that with the crop factor 40mm should be the right one. Anyone knows? Also, could this be used on an LX5? I know Panasonic has one 24mm for the LX3 but how is this on the GF1 and/or LX5? Thanks in advance! -iau
Stumbled upon this : the Diana 20mm viewfinder ! sold as part of their 20mm fisheye kit. Diana / Diana Products / Diana+ Lenses / Diana+ 20mm Lens I guarantee nothing about quality, though...
