I have been having fun with the GX7 for a month now and I will keep it until something better (in 4/3) comes along.
For me, its the best thing out coming from a GH2 that I returned, would have gotten a Oly but clipping on a flash was a deal killer, for me.
I was a SEMA in Vegas this week and must say outdoors the EVF (at times) was worthless, as bad as a LCD on the back. I have not noticed this problem prior to Vegas. I am ordering the eye-cup and hopefully it will satisfy this problem.
As far as the tearing or whatever I have not seen that issue, FWIW I do not wear glasses. On another note the sliding ocular adjustment is a PITA, compared to a rotary unit. I would gladly trade away the tilting EVF for one that didn't need to be flipped up to adjust it.
It may be me, but EVF focus on this camera is VERY elusive and never seems correct.
Had the GH2 wasn't impressed, sold it and have been waiting, and waiting, would have bought the E-M5 but I didn't want to deal with a clip on flash.
I was afraid the reviewers would rate it below the E-M5, guess I was right, they probably were also.
GX7 is pretty much what I have been waiting for. However, yesterday at the SEMA show in Vegas the EVF was as worthless as not having one. Did get some nice shots using my left hand to block the sun lite, One handed shooting is no problem, fortunately.
Am ordering the eye cup for the EVF, I bet that solves THAT issue, just hope it doesn't dwarf the camera.
I have not noticed any issue with the field sequential LCD other than the fact the sliding diopter is a PITA to adjust. I would gladly trade the flip up EVF for an easily accessed rotary adjustment.
That said, no way I would ever go back to a DSLR.
