[QUOTE="nickt, post: 639119, member: 4923"] Yes, I totally forgot camera thickness. The extending lens barrel is an unknown anyway to figure the distance from the front of lens to the subject at the closest distance. That website you listed has two charts, one for 1:1, and the 2nd chart for backing away to get 1:2, if I am reading it correctly. So that makes sense: WD of 115mm (4.5") for 1:1 and 206mm (8.1") when backing up to get 1:2. [/QUOTE]
