Where I go next is on my mind in the world of photography. I will keep my current body for astrophotography (6D), but would like to get a higher resolution body for landscapes, travel, etc. The 5DS(r) has been on my radar for some time now, as has the Sony A7r2 or 3. The IBIS would be a wonderful thing to have as I get older, as the cost of going to all IS lenses can be prohibitive.

I also expect to pick up my 2nd Tilt Shift lens next year, so IBIS might be an advantage on handheld shots. I find though, that the cost of Sony lenses to be too expensive for a hobby, especially to switch. I am happy with my current lens selection, and I am fine with using an adapter on the Sony camera.

I wish Canon would come out with a full frame mirrorless to compete with Sony (with a full size mount), but I suspect that would steal too much from the 5D series to make it happen any time soon.
