[QUOTE="nickt, post: 561996, member: 4923"] I haven't used one, but keep in mind the minimum [B]focus[/B] distance spec that they give you is from the subject to the sensor. To get the minimum [B]working[/B] distance (front element to subject), you need to subtract the length of the lens. So you might want to search out when and how much that lens extends when you are at the distance for 1:1. Edit: I forgot about the depth of the camera body. From the min focus distance spec you want to subtract the length of the lens and 46.5mm for the Nikon body depth. I found this site with a hard to follow chart that reminded me: [URL="http://www.jeffree.co.uk/pages/macro-lens-calcs.html"]Macro lens calculations[/URL] If I am looking at the right lens, the tokina has a 115mm working distance or about 4.5 inches.
