>>4153771Well there's a lot to unpack here and it's hard to say without knowing what settings you were using. The depth of field is awful on the M43 shot because there is not enough distance between the lens and the subject, as well as the subject from the background. But there could be other reasons too:
It could be because ISO is bumped up super high because of the slow lens? It looks overexposed so if you were in an auto setting you could be stopped down even further or your iso could be crazy high. A lot of factors go into this.
You could get a 40-150 2.8 pro for the price of that panasonic lens. That would be a better comparison.
