andalus Posted April 17, 2010 Share #1 Posted April 17, 2010 Advertisement (gone after registration) My Elmar 24 3.8 seems to be "focusing" beyond infinity on a distant object with the focus ring set right on infinity at the stop. Back it off a hair and the split images (of the distant object) comes together. Anyone else had this particular head scratcher. My other lenses, a 50 Lux and a 135 Telyt don NOT do this.

marknorton Posted April 17, 2010 Share #2 Posted April 17, 2010 The 24mm Elmar and 18mm Super Elmar both have steeply raked focussing cams to reduce the cost of the lens mount and this may make them less accurate, depending on the state of adjustment of the camera. The deep depth of field of wide-angles allows Leica some wriggle-room. Of course, the fact that the rangefinder appears to go beyond infinity doesn't mean the lens actual focus does and it would be worth focus bracketing on a distant object to chck how actual focus varies as you move towards the infinity stop.
