It definitely weighs more! However to get used to that all I did was pick it up everyday and do a few shots....When I picked up the K50 it felt LIGHT, like a toy!
K1 gets heavier depending on the lens....its pretty nice street shooting with a DA 40/50....but long telephotoing with the 135-400 I feel the weight.
OP, it may be a time to wait and see....a K3(iii) may be around the corner.Your lens line up shouldn't need much more if you get impatient and go with a K1( some of the DAs you have that you haven't mentioned may do ok @ FF....most work with 1;1 and all work in crop.
