I finally broke down and bought a Sony A7 II. I was and currently still am using a Canon 5D Mark II but realized that I rarely use it anymore because of the size and weight. I shuttered at the thought of bringing that camera on a trip.
So far I have been liking the Sony A7 II. The weight is not too much lighter than the Canon but much smaller. I have been using it exclusively with older manual focus lenses and some of them are pretty heavy.
