Anyway, the K-20 D's magnification factor is definitely 1.5X.
I think Canon has a 1.6x on some of their cheaper DSLR's, which have slightly smaller sensors.
Your questions about how to operate the camera with various lenses can best be answered by referring to the instruction book.
I have photographed the specific pages from the instruction book that deal with this.
Kindly refer to the attached photos for details.
Contact me if you have any other questions.
Weird - I got your first message by PM and replied that way, then the reply came again by both PM and publicly. I guess you're just pasting the same info, or is there some way to make it post both? In any event, thanks for the info. I'll PM you with anything else, just wanted to explain this odd looking exchange in the thread.
