Some good point guys, thanks for the input.

I'm not sure what the best option is for my needs TBH. Yesterday I was out on the hill and carried the E-3+14-54, OM50mm f/1.8 and EC-1.4. Really I'd like something lighter like an E-420 and 14-42. The problem is that the 14-42 while being smaller/lighter is also slower, the 14-54 or 12-60 pretty much negate any advantage regarding weight/bulk in using an E-420. Carrying a few primes (50mm*, 200mm*)in addition to say a 28mm* on the camera (if a 28mm prime existed) sounds like a reasonable solution (I generally use my 14-54 at 14 (28)) although it isn't always practical or desirable to be swapping lenses in a downpour.

* when I refer to 28mm etc I'm talking in terms of 35mm cameras, obviously I'd be using a 14mm. Thought I'd point that out before someone suggested the 25mm Pancake

Actually I'm really interested in a Ricoh GR-D, well I have been for some time. I must ask some question in the relevant forum
