No change up front
Though Panasonic has made some changes to the design for the GM5, it looks identical from the front. However, it's now made of magnesium alloy.
Bye-bye flash, hello EVF
Panasonic jettisoned the flash of the GM1, moving it to an optional bundled flash that fits in the hot shoe. Instead, the GM5 gets a small but serviceable EVF.
Although it's a hair bigger than the GM1, it's still a pretty small camera.
More on the back
Since the EVF forces extra space at the top -- the GM1's LCD went all the way up to the top -- Panasonic added some extra programmable controls and changed the back vertical dial to a horizonal one.
Panasonic adds its version of the short-uploadable-movie feature; clips can be 2, 4, 6 or 8 seconds.
It just has micro HDMI and USB connectors.
The camera may be small, but Panasonic makes room for a full-size SD card slot. On the other hand, the small battery still doesn't last nearly long enough.
