I have D5500 which I love and a bunch of lenses: af-p 18-140, af-p 18-55, af-p 10-20, 35mm 1.8G and Sigma 150-600 contemporary.
My photography is more or less evenly divided between travel, wildlife (birding mostly) and landscape. Being a not very advanced amateur I am reluctant to spend too much money for my hobby, but may be my camera is limiting me too much?
I feel that while as a travel camera my beloved D5500 is more than satisfying, for wildlife and more serious landscape photography it is not good enough.
I do not currently have enough budget to go mirrorless, so may be I just should upgrade to D7500? It seems to be a big step towards a better autofocus, 8 fps, much bigger buffer and at least my wildlife photography would be improved. I won't need to spend money for glass immediately, just for a better body.
On the other hand I can wait until a decent mirrorless system fits my pocket instead of buying an outdated body now.
So what is a more clever way in the long run: upgrade a body and start improving immediately or wait for a budget for a better system and improve my skills in the meantime?
BTW, in my country a new D7500 is $1000, and a Z7II with 24-70 F4 is $3900.
