Hi,
I'm new to Leica's and I have just bought an M4 but as I'm on a pretty tight budget, I bought a Jupiter 12 35mm lens. I've heard good things about this lens for the price but as it doesn't currently fit the M4 I've read that I need an adapter for it. Does anybody know the exact adapter I need? I've seen some on eBay that I think might do the trick but I can't be sure and I don't want to buy the wrong thing! Thanks.
