I've been trying out my new acquisition G1 today, and comparing it to my GF1. Firstly where the GF1 gains.
- Rear dial on GF1 feels more convenient to me than the front dial on G1.
- Excellent video on GF1 whereas no video on G1 (however I don't miss this as I have other cameras I use for video.
- It's lighter and smaller than the G1 so better for hiking in my opinion.
- Smaller size is not so useful with long lens as hard to hold steady
Now where I think the G1 is better.
- Live View Tilt screen, makes low angle photgraphy much easier on the knees, and much more convenient when using tripod close to floor.
- Although the viewfinder is nowhere near as good as on my DSLR it is so useful to have one.
- It has more modes on the mode dial, but I will seldom use these as I generally use Aperture, Shutter or manual.
- I like the top dial for focus mode, even though dpreview hated it.
- Viewfinder and more substantial body makes it much easier to hold steady with long lens.
- Card holder on side instead of on bottom means that the card can be removed without removing QR tripod plate.
All I need to do now is get out and take some proper photos with it.
