The most recent is here: Camera Lens News No. 31: http://www.zeiss.com/cln It includes links to a two part paper on MTF curves that I found to be very informative. Some of the examples are based around 12 & 24MP sensors, so that it is clearly recent. Discussions include the effects of focus accuracy, focus shift and other areas that I have not seen explained in other explanations for the layman. There are also photos to download to show particular characteristics against specific curve examples. I think it is worthy of a read for the technically curious. -- Cheers Geoff 'Life's too short for mediocre glass' http://gallery.leica-users.org/v/gh/a/ http://www.pbase.com/hoppyman
