I am thinking of moving from my current Canon 60D to a Nikon Full Frame D750 with the 24-120 lens.
I know there are supporters of both brands in the UHH but I can't afford the Canon full frames at this point and, at 72 years old, I'm not sure I will be around to fully enjoy a 5DIII or IV.
Am I thinking about this too deeply, or should I just go ahead and do it?
Thanks for any advice.
72 is not old by today's standards. You could live to 92 or beyond! Buy whatever will make you happy.
