This is indeed a lighter combination. However, it is not a backup for 1Dx. But whether backup is necessary or not is another matter. I do understand your need for less bulk and weight though...No doubt my next camera will be a sony. Most likely the a9 because the a7 series is a bit slow on the fps while tracking.Interesting! So I guess you will decide to either:
I want a small, lightweight camera to accompany my 1DX with me to sporting events. My 5Diii is bulky and heavy and is hard to carry easily all day while lugging the 1DX and 300 combo. Truth be told I could live with the a7s or a7ii as a backup camera but want to see the a9 before throwing down the money.
1. depend on the the metabones adapter
Most likely, in which case I would like to see how the 300mm 2.8 works with the sony adaptor.
However, in that case it is the weight of 5D3 against the sum of weights of both sony A7 and adaptor
2. or get a whole new lens system.
NOT likely, expensive and bulkier (the sum of canon and sony equipment).
In that case the weight of 5D3 is irrelevant.
I would purchase a native FE 35mm prime (or something close) and that would be my secondary camera/lens. I don't want to use a metabones adapter. I would get native lenses. My current need for a second camera is for pre-game, post-game type shots. I use a 300 2.8 on the 1DX during the game. In fact, this combo is together 99% of the time during football season.
