Time for a new camera thread. Just got home and the G2 was waiting. Went through the menus and did my setup and then immediately decided to start testing out the touch screen aspects of the camera. I think the touch screen is going to be more useful that some are thinking.
In particular, the touch shutter I thought would be weird and instead I think it is going to be really handy. You can't focus all the way at the edges but IRRC (and will double check how close you can get to the edge with the GF1).
Have to get used to the swipe to move from picture to picture as it isn't as sensitive as my iPhone/iPad. You can touch the screen wherever you want to magnify the view in that area.
It is going to be really hard to transition from the left key on the four way controller now doing film mode versus focus mode (which is now a dial on the top deck).
There is now a manual focus guide that shows you if you are moving the lens to closer or further focus. Haven't tried this with a legacy lens yet. Does't give a measured distance scale but in particular the 45 macro can benefit from this.
