So what are you telling us? The Canon "wife" has a larger body but no stabilization and the Sony "lover" is lighter but harder to handle?
Well, Wives may not be soo exciting but when they want they make the"job done" even better than "lovers"!! haahahahah!
Well, of course this is a joke. The thing is...i am a wildlife photographer/videographer and also a photojournalist. This is what I do for living. Make no mistakes, Sony cameras can give you huge results, sensors are quite good! However, i do notice difference from sensors like 5dmkIII or 5dmkIV, from the 1dx mkII I never noticed such a huge difference in image quality. There is not. It can be different of course...42mp vs 20mp but not noticeable at least in a way we can see it "side by side". Canon bodies and ergonomics are good.Period. Canon menus and camera consistency are good. Period. Canon is reliable i had never missed a shot and never got colors messed up with the 1dxmkII, however I did have problems with Sony. I never had problems with cold with the 1dx mkII ( andI shoot sometimes in antarctica and high Arctic) i did with Sony. In video, i just love Canon 1dx mkII 4k image, and also love Sony image but Sony requires a lot more color editing than Canon. I now shoot video with the Sony Fs5 mkII and the atomos inferno so i dont film with hybrid bodies, but the new 1dxmkIII made me think i can go back to hybrids. Lets see what comes with this new ones in video.
In resume....A "lover" can be exciting....but at the end of the day, a Wife gives you stability, reliability, thrust, confidence in all situations. Andd.....if you ask gently....they can do "wild things" also!!
Ohhh.....about stabilization: It´s very handy for video, mostly! But nothing that IS dont give you! In most of the situations, I do prefer IS, but that´s just me, i don´t record video handheld, most of the times is in tripod with long lenses.
You can see here a teaser of the incoming documentary in Antarctica: This shots were made with Canon 1dx mkII and Sony A7r3, shot s with the FS5 are not in this teaser:
