Re: Chuck: question regarding zooming thumbnails
Since the zoom feature wasn't designed into the body, it doesn't already have a ZOOM button, so it may not be obvious how to include it. If I were adding the feature, here's how I would implement it:
When displaying a preview image, holding down DISPLAY and turning the wheel on the back (Quick Control Dial) would zoom in and out. If you zoom out beyond the full image, it would go to 4-up, then 9-up (which is how it currently works).
While zoomed-in, navigation around the image would be like an Etch-a-Sketch. The wheel on the back would go left and right, while the main dial would go up and down.
