I almost always use the VF on my GF1. It's how I prefer to shoot. This morning my walk took me past our local park. In a tree branch right over my head was a small bird, a very intense yellow in colour. Distance from camera to bird was about 2m / 6ft.
Because the sun was over my shoulder I could not see the screen well enough to focus.
Sad. Love these birds, though I have no idea of their name. If I don't want the VF on camera, it will be in a pocket in future.
Sigh. That's my morning whine.
