Hi all, new to the forum as I don't yet own an m43 camera but I am considering selling my 5Dii and buying the OM-D. That's another story, so take that as given... With this in mind, which lens would you recommend for fast street stuff? I like the idea of the Panasonic G 20mm/F1.7 Pancake Lens but I have heard it isn't as fast as other lenses (fast as in auto-focus). The 40mm equivalent focal length is about right, though I am also thinking of getting a 28mm equivalent prime too. Fast primes for the OM-D? Looking for suggestions/recommendations.
