Hi,
The A7xII models are more solidly built. The A7, A7II and the A7rII have electronic first shutter curtain reducing vibrations. I would consider:
- The original A7 - affordable
- The A7II - a better version of the A7
- The A7rII - in my view the best of the bunch
What I own is the A7rII, and I use it mostly with Canon lenses using the Metabones IV-T (?) adapter. The lenses I have are the 16-35/4L, 24/3.5 TSE LII, 24-105/4L, the Sony 90/2.8G and the Sony 70-400/4-5.6G lenses.
I also have the Sony 28-70 kit lens. I don't really feel the Sony lenses are that compelling, that is the reason I bought the Canon 24-105/4L.
On the A7rII AF works with most Canon lenses, sort of, it is accurate but not very fast. Sigma has a new adapter that has better support for Sony functions.
The A7rII has the best sensor and the best PDAF, but I understand that you are under a limited budget.
If you don't shoot in the 1/15s - 1/150s range, the A7r may be a very good option, too, especially if you get a used one. The shutter vibrations on the A7r are well documented but the camera will still deliver something like 24MP of resolution in the affected speed range.
Best regards

I'm looking to add a Sony body and meta bones to my existing Canon kit to take advance of the better dynamic range.
I shoot architecture and will continue to use my tilt shifts and am hoping to do this without breaking the bank (my bank is a brittle one and prone to breaking!).
Is there a great deal of difference between the different models and is it advisable to land on one of the earlier models than the A7RII?
Also are there any good zooms for Sony that would allow the camera to double up for casual shooting.
Thanks
KP
