Beginners recommend a camera (SLR, micro-single), which can be used for taking photos and videos, mainly for office photography and conference photography?

You have the old flagship Canon SLR, and the lenses are all Canon's, so it is better to buy Canon SLR or micro-single. Otherwise, the original lens can no longer be used, which is a great pity.

If you have enough budget, you can consider Canon's micro-single, which is more portable than SLR, and shooting is not as tiring as SLR.

For example, Canon EOS R6 micro-single, listed in August 2020.
