Should I buy a dslr in 2026?

Here is what the site says about that.

From Nikon D750: Nikon D750: A DSLR by Nikon with a 24.3-megapixel full frame sensor, announced in 2014. Old, but a classic used full-frame buy.

From Canon EOS 5D Mark IV: Canon EOS 5D Mark IV: A DSLR by Canon with a 30.4-megapixel full frame sensor, announced in 2016. A workhorse, and a good used buy for anyone who already owns EF lenses.
