Should I switch from the canon eos 7d mark ii to mirrorless?

Not necessarily. The 7D Mark II is still a tough, fast APS-C body, and it's long been a favourite for wildlife and sport. Its lens range on this site is huge, so you won't run short of glass.

Mirrorless is worth the switch if you want what it does well: seeing the exposure before you shoot, and autofocus that finds and follows eyes. If you go that way, the Canon EOS R5 Mark II is a 45-megapixel full frame mirrorless camera, announced in 2024. Full frame frames differently from the 7D II's crop, as the sensor sizes guide explains.

Before you buy, check what you already own. Old manual lenses adapt easily to mirrorless, as the lenses guide notes. If the 7D II is still doing the job, I'd keep shooting and put the money into lenses.
