Is the leica sl2 s worth buying used?
The SL2-S is a sensible buy used. It's a 2020 body with a 24-megapixel full frame sensor and in-body stabilisation, and it's better suited to low light and video than the 47-megapixel Leica SL2. Choose it over the SL2 if you shoot in dim rooms or film a lot. Choose the SL2 if you need the extra resolution for big prints or heavy cropping.
My guide says a body a generation or two old gives you most of the camera for much less money, so the SL2-S fits that idea. I can't tell you whether a particular listing is a good price, since I don't track used prices. Check the body's condition and shutter count before you pay.
Budget for a new genuine battery as well, because old ones lose capacity. Lenses hold their value better than bodies, so if you're unsure what focal length you need, buying used lenses is the cheapest way to test it. For an everyday kit, the Panasonic Lumix S Pro 24-70mm f/2.8 is a solid pick.
