As you can see by my signature, I have a reasonably complete :43: kit. Two bodies: the larger and more-versatile G3 and the very-compact and fun E-PM1. Plus, I have a run of zooms and primes from both Panny and Oly that pretty much cover the everything except extreme wide angle. You'll also notice that I do not own any of the very expensive :43: lenses. In fact, my most expensive lens (all were purchased new) is the Lumix 100-300 and even that was still just under $500. Everything else ran in the $300-350 range or was part of a camera kit. I am now at a point were I can suspend adding to my :43: kit... or proceed to more expensive glass, starting with the Leica 25mm f/1.4 Summilux and moving beyond to the $800 range with lenses like Oly's 12mm f/2.0. But we also have, with the Olympus E-M5, the first :43: camera body with weather-resistant sealing and it appears Panasonic won't be far behind. So this naturally gives me pause. So my question is - and I'm just thinking aloud here - will ultimately most of us, including me, be purchasing bodies with WR, requiring lenses with the same? Does it make sense to continue picking up existing :43: glass with the current scenario before us? Or is it more likely we'll pick up one or two zooms in the future to take care of our WR needs? Just my musings here... I'd be interested in learning what the rest of us think.
