I had m4/3 for YEARS. I'm not talking out of my ass. I had the 17/1.8, 45/1.8, and 75/1.8. It's a decent platform if you want to run small, cheap primes for sure, but they aren't world beaters and posting like they are CONSTANTLY is disingenuous at best and annoying at worst. I got tired of bad bokeh, shit AF, and uber-small bodies...the platform on a whole is definitely more suited to AF-S casuals who aren't shooting any action to speak of, and once you get into pro-spec bodies and lenses, you're spending just as much as a MUCH better APS-C setup.
Oh, and
Zefah just because I'm a pedantic little bitch, there really are no analogs to the RF launch lens in the Sony world except for the 24-105...which Sony just raised the price of theirs so it's now $300 more than the RF Canon.
There's no Sony version of the 50/1.2,
28-70/2, or 35/1.8.
