As far as i can tell, the GX-1 is an update to the GF-1 / GF-2 body style, but with the G3 sensor and internals. That’s the 30,000 foot view of it, anyways.
So, what are the technical differences?
The GX-1 improves on the G3 with:
- electronic level
- a bit smarter button layout
- tacky rubbery grip areas for better, um, grip
- slightly faster autofocus (0.09 sec vs. 0.1 sec for my G3)
- slightly faster frame rate and larger buffer – 4.2 fps vs. 4.0 fps, 9 frames vs. 7
The G3 boasts these features over the GX-1:
- integrated EVF
- articulating screen
- longer battery life
For fans of the GF series, I suspect the GX-1 trumps them all and should be an obvious upgrade.
For me, I could use the level and the better button layout, and I’d love the better grip. I’m not sure it’s worth swapping for, though. I think I’ll try to add some grippy faux-leather stuff to my G3 and call it good.
