I owned a EM10 a EM10 Mk2 and a GX85, My understanding the Mk2 and the gx85 does not have the anti alias filter. The images from the EM10 mk 2 and the gx85 are a smidge better than the EM10. There is not that much difference I notice it when I check my images at 200%. I done know if I would base a buying decision only on this. The GX85 is a lot different camera from a OMD. I only bought it to shoot 4 k video.
