While the high price of an A7 probably slowed new customers rushing to Sony over Olympus I think the primary reason customers stuck with Olympus was "vendor lock-in" with lens mounts. People likely bought multiple m43 mount lenses to go with their Olympus or Panasonic. A customer would be more likely to buy another one of these brands if they had an existing lens collection over switching to the A7.

Note: I am reluctant to use the term vendor lock-in as the idea behind m43 was to have multiple camera manufacturers adopt a common lens mount. The fact that Sony and Canon have their own mounts is a net negative in my opinion.

Yeah, much more than body prices for me has been lens prices.

A 25mm f1.7 m43 lens is $150. I've got multiple. I don't mind putting them in kinda-risky places on my cheaper bodies if it makes sense.

A 25mm f1.7 M4/3 lens is equivalent to a 50mm f/3.5 lens. Which costs about as much on a FF body - as part of a zoom lens.

In fact, the much better Sony 50mm 1.8 also costs about 150$.
