Recommendations for a backup to the EOS 80D

[sunshan]

I have an EOS 80D for work with a couple of lenses and need a backup that will fit the lenses.

Why not another 80D? What are you looking for in a backup camera?

Which lenses do you have?  Are they EF, or EF-S?  Asking simply so we know if we should suggest any full frame models vs. APS-C.

Are you looking for improved features, or just similar to the 80D?

What is your budget?

"Why not another 80D?"

Agree the logical choice but how about a 90D and making your current 80D the backup.
