I really wasn't thinking about it until I ready about Pixel Shift today...mind blown.
Exactly, although I see limited use for it unless you are ready to do a lot of re-touching, or... the wind is very calm. Under those conditions the results are pretty exciting. Frankly the pixel shift isn't my biggest motivator. I'm more interested in the DR, the resolution, and the fact that it weighs a bit less and is smaller than what I'm using. The FPS is pretty nice when you need it too although I rarely do. I do wish they had a built in GPS, I have found that very useful, shortens my work flow a good bit. I'm going to keep thinking about it, I can't really complain about what I'm using but if I move I want to be able to use the lenses I already own I have no interest in selling off and buying glass again.
One thing I am planning on doing for sure is selling off the lenses I don't use (24L, 50/1.4, 85, 24-105) as well as the 5D and 5d2 body along with a lot of accessories, including a few camera bags and picking up a Fuji Xt2. I like what I see with them, and I want something I can keep handy all the time without taking up too much space that gets me good image quality too.
