Thanks for all the reply’s plenty of interesting food for thought, Unfortunately the person who was buying my last canon body has pulled out etc, so it’s back on eBay with a £1 fees offer, hopefully I can squeeze some extra value out of it.
The sensible solution will be the 7iii, as trying to do more weddings etc, but at the same time I do a lot of landscapes etc so the extra resolution has some benefits as well, a well priced 2nd Rii shouldn’t hopefully lose any value so might be an option to get it have a play see how it goes then sell on for hopefully the same price /very little lose. Will just have to wait and see and hope the grey import price further drops on the a7iii not in a huge rush either.
