I have an older DX Nikon body, and am unsure about my options for upgrading while still using my existing DX lenses. Would such a question be on topic for this site - ie it'd boil down to essentially "am I stuck with the latest DX-bodies, despite them being 4 or 5 years old, or are the lenses I have usable on the newer mirrorless Z-series, if so, to what degree of usefulness".
I'm not looking for product recommendations or anything of that nature, just general compatibility between my existing kit and potential future proofing of a fairly substantial purchase.
