Two questions: 1, Am I correct in my assumption that it is actually 1:2 macro and not 1:1 ?? Comparing image sizes in the viewfinder it would appear to be 1:2. Are there any specific / dedicated close-up filters / lenses to be added to make it 1:1 ?? 2, On the focusing ring there are 4 scales. The bottom two are the marked distance in meters and feet. The next scale appears to be magnification 1:10 9 8 ... 2 (which also makes me believe it is only 1:2 magnification) anyway .. the next scale is a mystery .. PN with a series of numbers and then brackets indicating certain f-stops. What is that all about ?? Hi Neil, to make 1:1 you need kind of a distance-tube (sorry, my english is too poor to find the special expression) made by Nikon just for this purpose. It is without optic. Using this, the "mystery-scale" will explain itself: you will have scale 2.......1. Happy Chrismas to all of you Rainer
