Thanks for all the suggestions!!!
Today I'll go the local store and I'll try several bodies and lens.
I'm trying to narrowing down to few options, here what's in the list so far:
Canon 5D
pros: Fullframe, well established brand, I already own the 17-40 and 70-200
cons: BIG, i have a 20d which i don't use very often as it not so portable, no pancakes
Pentax K20D or K200D
pros: pancake lens, Zeiss primes lens, relatively cheap
cons: zoom lens below average, no plan to eventually move to full frame,
Olympus 420
pros: Small, nice pancake lens, 12-60 zuiko is great
cons: 4/3, no fast primes except for the 25 summilux which is way to expensive
Nikon D60 D80
pros: good lens choice, not too big, well established brand
cons: no metering with manual focus lens
Zeiss IKON or Leica M6 or similar
pros: rangefinder, small, discreet
cons: not digital
I will be happy to get a nikon d60 or d80 but the fact that they don't meter with manual focus lens is really annoying. the d200 or d300 are quite bigger in comparison. I'm quite intrigued by pentax and olympus but for some reason i don't feel comfortable to commit to a niche brand. of course the Leica M8 will be the solution for all my problem but unfortunately is out of budget.
please share your opinions...
thanks again for all your help
