Jump ship to Sony alpha?
For ages I've had my eye on a Canon 5D mark 3 or 4, as an upgrade to my trusty old 7D, however it's been difficult to justify the expenditure. I'm after low light performance and AF speed/accuracy these days, both of which the full frame 5D do nicely. However, the obvious size of these bodies is starting to lead to my gaze being distracted by the Sony alpha range.
I would be tempted by something like the a7, or maybe stick with cropped sensors and look into the a6500. I understand there's a few adaptors out there allowing the use of Canon lenses on these Sony bodies which would be a big benefit, as I would prefer to stick with my current lens setup - EF-S 17-55mm f2.8, EF 50mm f1.4, EF 70-200mm f4L. This setup suits me very well, particularly the wider aperture on the 17-55mm f2.8.
1. Is the low light performance of the a6500 a leap forward compared to my 7D? (I know the a7 is a huge difference, being full frame and all.
2. Will my lenses (above) be fully operational on a Sony body, with adaptor?
