I am using a Canon G5 with the ring flash to take macro photos of coins. The manual is confusing me as to what settings I should be using. On the page entitled Macro Mode it says to press the "flower button" to enter Macro Mode, but it does not say anything about what to set the mode dial at (Auto, P, Av, M ?) I am trying to get very crisp photos of the surface of the coin, or a particular area of a coin or the edge reeding, so focus is critical for detail. Invariably when I begin to take a picture the focus goes in and out and invariably ends up out of focus. Then when I push the manual focus button, the camera goes out of macro mode and I have great difficulty getting the image as seen through the viewer in crisp focus. I have diopters of 1, 2, 4, & 10 which I have tried at various zooms, but the focusing is still the issue. Am I doing something wrong? The manual also mentions the 250D close-up lens which "makes macro shooting easier". From other threads it would seem that this lens is merely a +4 diopter. Is that true or does it somehow allow easier focusing and why is the range in macro mode as close as 2 inches but with the 250D it becomes almost 4 inches? It doesn't seem to make sense that in putting on a close-up lens you have to get farther from the object.
