Am very tempted by the E420 due to size and weight considerations. Combined with the pancake 25mm lens, the system is quite small. From a cursory look, it seems that there are no 4/3 wide angle primes around - one is stuck with zooms ( eg, 11-22, 12-60) which are bulkier and heavier, somewhat defeating the purpose of the small body. While the E420 weighs in at 13+ oz, the pro zooms are in the range of 16 oz. A Pentax 200D, while significantly heavier (23+oz) can be matched with pancake lenses in the 4-5 oz range. Are any third party small prime lenses adaptable for the Olympus bodies?? Or rumours about future production?? With more pancakes, the system would be perfect as a travel/hiking setup. Certainly lighter than my Mamiya 6!.
