GH3 with a 12-35mm lens.
It got hot yesterday here in central Texas. About 96 degrees by the time we wrapped up the day. I'd spent the previous afternoon at Eeyore's Birthday Party with my new GH4 and I decided to take one of the GH3s out to see how the older model compared. The feeling of the new camera was still fresh on my hands.
With the exception of the better EVF on the GH4 they both feel and handle the same to me. I went out to do a preliminary scouting for a project this morning and I took the two GH3 cameras along with their respective, fast zooms. They felt and performed just right. Nice to have three nearly identical shooting cameras for a change. Feels like the film days.
