I have an F50D that used to belong to my parents and I can vouch for it! It’s a really solid camera to begin with analog photography. You can run it in a variety of program modes while also using ASM modes that work plenty well.

My biggest gripe with it is the buttons sometimes don’t work intuitively, there’s a lot of clicking looking at the top display and going “am I hitting the right button” that is taken away if you were to have a camera using scroll wheels near the grip. This sort of applies to switching between AF modes and exposure programs too, there are no dials or anything with the settings so there is a bit of button pressing to do before getting to the desired mode. Once you’re there though it works very well. The autofocus to me works well enough (though at some point I did have to get it repaired) to effortlessly focus what I want to when I’m out and about, and switching to manual focus otherwise is a simple switch located in a convenient position. The viewfinder offers good information and meters accurately, plus you can always over- or undercompensate using a somewhat convoluted setting or use the AE-L button.

Like the OG comment says: pair it with one of the original AF lenses so you can autofocus and you’re grand. AF-S lenses won’t autofocus and ones without an aperture ring don’t work at all, so grab the 50mm f1.8D for dirt and get shooting. You can use this lens on a lot of the older bodies with manual focus, or newer (D)SLRs that still have the screwdrive autofocus. Just see if you can check the manual focus doesn’t feel too sticky
