>>4390464I have seen people selling used sony a7s, nikon d850s, and canon 5divs that were one with their accumulated grime and had shutter counts over 400k
If you only use electronic shutter, never cull on camera, only use the USB port (sturdier than card slots) to copy photos, and always take the battery out to charge before it dips below 20%, your camera will last as long as possible. Most likely 40-50 years on the camera body, 5-10 years per memory card. Some fancier lenses with lots of IS and multiple AF motors may only last 20 or so years but simpler lenses can easily last 50+.
With rugged, simple kit that can always be in eshutter like an a9ii/i and one of the smaller primes, an om1 and a prime, or a z8 and a 1.8 prime (sturdiest simplest build) you could use your gear past the point of gradual LCD death. Stuck pixels on 24mp+ are easy to interpolate out so that’s not even a huge issue. I’d just avoid makes known for sudden unprompted death like panasonic and leica.
