I don't know how you can see anything outside that frameline. Due to the (smaller than 24x36) sensor crop, that frameline shows you an approximation of the crop effect (about the same view angle as a 32mm on a film M) To use a 15mm lens you should use an external finder which is designed for a 21mm lens on a film M. All of the framelines show less than the actual sensor capture anyway. (they are calibrated for the view at .7m) The key is to think of the framelines as approximating the view angle, not the nominal focal length. Each lens produces the same image at the plane of focus on any M. The M8 sensor, being smaller than 24x36, actually captures about 75% of it.

A 21mm lens on the M8 just about fills the M8 viewfinder... a CV heliar 15mm lens on the M8 is really a 21mm lens, and can be used with a 21mm external viewfinder... so... can one also use the M8 viewfinder, as the viewfinder for a CV 15mm lens...? Why is this so difficult? (a yes or no answer is inadequate, without some logical explanation... please) thanks, Steve "I never wanted to be famous" http://www.blurb.com/bookstore/detail/186890 _______________________________________________ Leica Users Group.
