I currently own both the 16PM and the 17. I have a young son so I do sometimes use the telephoto but damn I would be remiss to not acknowledge how amazing 17 feels in the hand. ONe handed use is perfect, it isnt too heavy. I am contemplating letting one device go but can't seem to make up my mind. Has anyone else made the switch from a pro max to base 17? How has it been? Do you regret it?
