Agree about 16MP being a sweet spot, at least as long as you view on <= 4K, but this people only come to know after they bought into the M43 system, and they will never know it, when not...the 16mp m43 sensor could be a 'sweet spot', just as it is for the aps-c 16mp sensors.. where it works well with the existing lenses..and started into more serious photography, I'd buy the 24MP Fuji, which is not only superior in most specs, but also at least 20% cheaper.
Some people here want 16 MP for ever, but this will kill M43 in the long run. Just you wait.
