I've been using my E-P1 as a toy alongside my 5D2 for a few months now and realise that I get a heck of a lot more pleasure from the Pen. So I've sold the DSLR and will get an EP-3 when available. Up until now I've been playing with MF legacy lenses as the kit lens isn't very impressive and found that, while I love them, they are not always practical. I'm off on a vacation to Italy in a couple of weeks and I'd like to buy one decent walkabout lens, preferably Olympus. Preferably a zoom. What do you recommend? What is my best IQ option? (I'll be taking a couple of Contax MF primes along too.) Many thanks in advance for your thoughts and suggestions.
