When you check the Product Specification for Canon lenses here:http://www.canon-europe.com/For_Home/Produ...enses/index.aspYou will find that all new Canon L lenses (50/1.2L, 85/1.2L, 16-35/2.8L, 24-105/4L) have the new feature "Distance information". The older lenses don't give this information (Canon gave some weak reason for this up to now). Could this mean that Canon is planing to relase a lens correction software module for the computer or camera, like DXO or the Hasselblad 28mm? What do you think?Best,JohannesP.S.: If I have missed an earlier discussion about this, I'm sorry.[a href=\"index.php?act=findpost&pid=119261\"][{POST_SNAPBACK}][/a]
Flash is indeed the reason.Other brands, like Nikon, have been measuring subject distance with their lenses for many years. This can be checked by the presence of the D letter in the lens name, like in AF-D.Regards,Bernard[a href=\"index.php?act=findpost&pid=119272\"][{POST_SNAPBACK}][/a]
Bernard,How accurate are such distance measurements and are they displayed anywhere before taking the shot?[a href=\"index.php?act=findpost&pid=119281\"][{POST_SNAPBACK}][/a]
...or the Hasselblad 28mm? What do you think?[a href=\"index.php?act=findpost&pid=119261\"][{POST_SNAPBACK}][/a]
