Jan,
Yes I know the picture really didn't help illustrate my focusing problem. But I thought perhaps it might excite someone enough to respond to my question. I hadn't seen your first post yet. Call it faith in the power of Leica porn.
Focusing on this camera is completely different from what I am used to. My first and only camera for decades was a Pentax K1000. The split image focus of the rangefinder is so alien to me I can't always tell what I am supposed to look for. Using the moon and playing with the diopter with the lens set at infinity has given me the point of reference I lacked before. As for sharpness, I think it looks pretty good. But I'm sure I will know better after using this lens more and trying a few others out.
Thanks again. I really appreciate your advice. I tried using the Google to answer my questions for several days and come up empty handed.
