I have been married to Canon since the 10D eons ago. It has been a decent relationship but, lately has become a Love-Hate relationship.
I really enjoyed my 40D and 7D cameras and absolutely love my 7D2. I needed a full frame camera because the area in which I shoot my dog portraits doesn't allow me enough room to back up far enough to capture a larger dog with the 70mm side of my 70-200mm f/4L IS lens which is my lens of choice when shooting dogs.
A few years ago, I found a 5D2 that was in minty shape at a very good price. I sold my 7D and the proceeds came quite close to funding the 5D2. I really liked that camera and began to shoot people outdoors using the 70-200mm lens on the full frame and a 17-55mm on my 7D2. That was a great focal range combination because there was no gap in coverage between the two lenses. In fact, there was a bit of overlap in coverage which I like. However, the AF of the 5D2 was not all that great.
I made a big mistake and purchased the 6D2 without researching the camera. There are some things that I really like about the 6D2 but many things that I absolutely detest... Primarily, this has to do with autofocus when shooting with the eye level viewfinder. In a word... The eye level AF of the 6D2 simply sucks with the 80D style AF array centered in the middle of the frame. It is nasty for shooting portraits since the highest AF point places my subjects eyes towards the center of the frame. Focus and recompose is O.K. in a studio setting but is not feasible outdoors when shooting with a very wide aperture to blur the background. Using live view with the excellent dual point AF and face detect would solve that problem but, I just don't like using live view outside. I find myself choosing the 7D2 over the 6D2 more and more.
I have been researching cameras, especially along the Sony line; since with adapters, I can still use my great Canon glass and since bu just purchasing a new Godox XTPro trigger, I can use all my Godox equipment.
At first, I was attracted by a used Sony A7Rii which a local guy is selling (the A7Riii is too expensive for me to consider). However, with the advent of the A7iii. I am looking into that camera. However, I want to find one to rent for a weekend of shooting before I make my decision...
