2. My current G1 seems to have very limited DR and in low light fails to display detail clearly visible by eye.
With Sonys you can adjust the jpeg settings (Creative Styles), so you can set it to -3 for saturation, contrast and sharpness. You can then see those effects through the EVF - giving you a great dynamic range. If you have the camera set to jpeg + Raw, you can use the Raw file to avoid the jpeg adjustments. It's not the best answer at the moment but it works. Shadows definitely become clearer and are lifted, more than my eye can see.
