Is the canon eos 6d mark ii worth buying used?
Yes, I think the 6D Mark II is a sensible used buy. The buying used guide makes the case: a body a generation or two old is often most of the camera for much less money. The 6D Mark II is a 26.2-megapixel full frame DSLR announced in 2017. It has no stabilisation in the body, so pair it with stabilised lenses for slow shutter speeds.
Budget for a new genuine battery when you buy, because old ones lose capacity (see batteries). If you want to spend even less, the original Canon EOS 6D is another cheap route into full frame, with 20.2 megapixels.
For everyday shooting, the Canon EF 24-105mm f/4L IS II USM is a solid all-rounder. For portraits and sport, the Canon EF 70-200mm f/4L IS II USM gives you stabilisation without the bulk of the f/2.8 version.
