When it\nfritzs out, the AF and OS (autofocus and optical stabilization) stop\nworking, and the camera either gets wonky data from the lens, or no data at\nall. <span class='nobr'>In the former<\/span> case, the lens tells the camera that the settings are\n<b>7,500mm <span class='f'>f<\/span>\/95<\/b> (!), and in the latter case the\ncamera thinks the lens has no CPU, so defaults to whatever I've set for\nnon-CPU lenses (which is the 100mm <span class='f'>f<\/span>\/2 settings <span class='nobr'>I\nuse<\/span> with the dreamy Zeiss used for the pics on <a\nhref=\"\/blog\/2009-11-23\/1368\">this post<\/a>).<\/p>\n\n<p>Take your pick, 7500mm @ f\/95 or f\/2 when you know you're zoomed at\n1,000mm and it'd be comical if it weren't so annoying.<\/p>\n\n<p>It happened a few times on Mt.
