It's all tradeoffs. Reflex cameras are pretty standard, also the electronics have been around for a longer time now. But there is a balance in getting things to

* have all the basic and possibly premium features

* be rather compact and portable

* have the right weight

* possibly be weather/waterproof

* process images fast (including video)...

* ...don't drain battery in minutes...

* ...but also don't overheat in users' hands

* etc

The R7 is not a reflex camera at all. There's no mirror anywhere.

And all the electronics and the shutter are still the same. Being mirrorless, it adds an EVF in the place of a mirror and prism.
