This is a very good price on a very good mirrorless camera, with a decent lens.
I love mirrorless, and have been a fan for years. KEH.com, a good site for buying used gear, lists this combo for quite a bit more.
The “new” mirrorless cameras are great, but virtually ALL digital compact cameras made in the past 15 years are also mirrorless. Only DSLRs had mirrors.
I have a couple of Canon Powershots that have a “live” preview where you can adjust exposure, saturation, tone, etc. and see it on the live screen before taking the picture. The lenses do not come and the eyepiece viewfinders (if any) are optical. 12 and 16 MP, $5 and $7 at a thrift store. No doubt ditched for a smart phone with a camera built in because they were “too complicated.”
