Dear Roy / All

I believe, from personal experience, that whilst other group members have given you some really good advice, there is another matter which I feel should be taken into account.

Around 2 years ago when there was a shortage of Z9's, I really wanted one [mainly focus & shutter speed] but none were available in the UK & delivery completely unknown, I had a special shoot to do for which the shutter speed & the best focusing system possible were available to me so I opted for a D6 in the absence of a Z9

Very shortly after purchasing the DSLR body, the Z9 was plentiful in the UK, however, the trade in price was horrendously less than I paid for the DSLR & I've tried a couple of times since - in essence, now, I've lost ?5k or slightly more & that's as a great trade with a body having less than 7k shutter count now & excellent A++ body condition.

Roy, I'd personally be seriously considering changing to mirrorless before buying a new DSLR.? My wife has a Z7 II but I've not got involved with it, so unable to comment or verify first hand, I have heard that changing to a mirrorless is a steep learning curve.? A good friend has a Z9 [for motorsport] and he learnt sufficient in 2 days to enable him to be competent for his next pro shoot.? My wife hasn't grumbled and I see quality images from her. YMMV

Just to reiterate, in my opinion, I'd be seriously considering a mirrorless body & F2Z adapter.? Others may have a different view.

Just my 2d worth?

With my best wishes

Rob.
