With the z camera you will forget about problems with focus on some lenses. All old lenses will focus absolutely accurately.
@andrewgusew Thank you for your suggestions.. I recently checked out more used Z7ii's which have been high mileage and priced beyond my budget. The lens recommendation sounds good.
Thank you.
Latest used price at a store: Z7ii with 40,000 shutter count selling for $1500 and then look for a lens. This is beyond my budget as I am unwilling to part with my D850's.
A used D850 with same count is selling for $1,100... I might use my wife's D7000 (my gift to her that she never uses) with 16-85mm G lens, when we visit Colombia; her family and firiends have warned me about the current security situation.
