I bought a D700 off ebay some time in 2019ish before the youtube people made it inflate in price.

I don't see a reason to upgrade, everything seems like diminishing returns. Don't need any more megapixels, autofocus is fast enough, build quality is great, body is a tank, color science is great, great lens ecosystem.

What are honestly the advantages of upgrading? More muh megapixels? I don't see the point when this thing is perfect. Even the newest hottest most basedest 2024 shit is like 10% better at most, and thats in niche scenarios.
