Have you never been annoyed at how live view stops updating and the live histogram stops working once the shutter speed hits 1/1000 second in manual mode?
I like the GX7 too, but those silly limitations really turned me off on it, and quickly, as I often shoot at f2.8-4 outdoors and like relying on watching the histogram and/or live view to see how my shutter speed and/or aperture changes are affecting the exposure before I press the shutter release and with the GX7, once that 1/1000 second ceiling is hit, you're done, left in the dark, literally, as the screen stops updating and you don't see what the resulting exposure looks like until you review the image if you happen to have selected any other shutter speed between 1/1000 and the 1/8000 second top speed. Obviously, with many of the files in this thread, 1/1000 second was well short of what was being used. The images are beautiful.
If one were using any other exposure mode, be it program, aperture priority or shutter speed priority, the limitation disappears. It's only in manual mode that Panasonic limits the live view and live histogram of the GX7 to the 1/1000 second maximum shutter speed.
For a camera to be as loaded with features and then place such a limitation on the manual exposure mode is just plain silly.
