Compare Canon DSLR and Sony A7RII underwater?

[Tim-O]

I am in a unique spot and upgrading cameras/housing. Does anyone have experience with the A7RII and the 5DIV underwater (or 1dxII or even a 5dIII) that could give me a comparison and/or pro/cons for underwater?

I have always shot canon, and love them, but looking to trim a little weight/size from the carry on bag lead me to consider the A7RII.

I have borrowed and shot both above the water, but before I invest in housing, looking for first hand underwater experience?

Anyone use the Metabones adapter w/ Canon Glass on the A7RII underwater? Thoughts?

If you have canon lenses go with the Mk IV. In actual practice with 2 strobes and a focus light and arms you will be saving precious little weight and you will have one of the world's best autofocus systems. The A&RII just doesn't focus in the same league as the Canon and if you try to use Canon lenses on the A7 then it gets even worse.

IQ is comparable, so stick with Canon in my opinion.

Thanks Bill... I am leaning pretty hard in that direction.

Out of curiousity - have you played with the Sony much?

I did and tried to use it with the Gen 4 adapter and the Canon 100 macro. Painfully slow, but very nice quality when it actually focused.
