Thanks Fatfish and Mr Andre for your contributions. I'm sure there will be people with thousands of posts quick to dismiss your opinions. I think you explain quite well your concerns about Canon. The comment "I love Canon, but I am close to jumping ship" for me is relevant. Having tried the A7R III I was quite impressed how much Sony had moved on. Eye focus was excellent and Silent shutter too has many uses for me. I'd like my next camera to be a Canon. Of course full frame mirrorless is a big step for them but its not like last week that they started working on it. They've made mirrorless cameras for years but while they sell well they are not best in class at APS-C level. If the new Canon full frame mirrorless is an average camera then my next move has a high chance of moving to Sony which would disappoint me but that's progress. I was quite happy with Nokia at the time. It had a great battery life and very reliable but couldn't connect in a user friendly way to the internet or run decent useful apps. It started as a trickle but reached a tipping point.
