Having seen their article covering the most sold used cameras of 2020 I wanted to produce my own top 10. I expect it would look quite different, unfortunately I just could not pull the data together in an easy to digest format. The problem remains that there is no consistency between retailer products that allows me to tie them together.

Here is the list with links to help you find these used cameras on the UsedLens.co.uk website and search for the best prices.

1. Sony Alpha a6000
2. Canon EOS 5D Mark III
3. Nikon D750
4. Canon EOS 5D Mark II
5. Canon EOS 5D Mark IV
6. Fujifilm X-T2
7. Canon EOS 7D
8. Nikon D90
9. Nikon D810
10. Sony Alpha a7III
