I'm tempted to sell a number of my native :43: lenses and get the new Lumix 12-35/2.8, but that's not my reason for posting here. I'm equally tempted to find an Olympus OM-4T and get a set of f/2 primes for it (24,35/85). Somebody talk me out of it before it's too late! You may suggest the 24/2.8 and 35/2.8 instead of the faster f/2.0 versions - but if I got the Lumix 12-35/2.8 it would be rather pointless, wouldn't it? I've tried a few adapted lenses, and I'm hooked. But I think I'm having a G.A.S. attack on both the native digital side and the adapted lens side at the same time!!. Oh, the humanity!
