Great, but not very reliable

They share the same 16Mp Panny sensor. Only difference is the sensor of GX85 has the AA filter removed for a sharper SOOC jpg output and it is on a 5-axis floating design.

I think it`s a newer design - pretty sure the scan rate is faster and the filter stack is a new design which doesn`t let in dust ..

I find that the AA filter removal makes a lot more difference to RAW output than JPG,..... JPG sharpness difference in cameras is mainly down to the in-camera processing .. the amount of Noise reduction at base ISO (it`s usually excessive even on lowest setting) and the radius / amount of unsharp mask used by the JPG engine, the Difference between a weak AA filter like the GX7 had and none at all would have little effect on the typically greasy JPG engines in cameras (Squeezing fine detail = far more CPU time & power ) - Sony and especially Canon seem to be pushing the boat out regarding scavenging fine detail from OOC JPGs,.. Panasonic , Oly , Nikon and Fuji far less so ..

IBIS is better too but basically no grip to speak of so button crunchy when picking up or using with longer lenses, for some silly reason it doesn`t have the D-Pad disable option like the GX8 which would fix that

One more thing, 14~140 f/3.5-5.6 still suffers shutter shock on the new m-shutter of GX85. E-shutter is still the best shutter option for this lens.

I never had it in the 2.5 years I had a GX80, I rarely used the E-Shutter on that camera and the 14-140-II was on it most of the time
