Read about the 200mm Micro-Nikkor AiS IF here<\/a>.<\/p>\n Read about the Nikon PB-4 bellows here<\/a>.<\/p>\n Unlike the optical unit of the 135mm Leitz Elmar or the 100mm Macro-Elmar-R, both of which permit infinity focus all the way down to a 1:1 reproduction ratio, the optical unit of the 200mm Micro-Nikkor AiS IF is not detachable. But that does not disable it for higher reproduction ratio macro photography. The focus range of the lens mounted directly on a camera body is from infinity to 1:2, or half life-size. So I thought it would be interesting to see what that focus range becomes when the lens is mounted on the PB-4 bellows, which requires no adapters.<\/p>\n a) With the PB-4 collapsed and the lens set to infinity, the reproduction ratio is 1:2, or half life size. That’s exactly as close as the Micro-Nikkor can focus mounted directly on the camera without the bellows.<\/p>\n b) With the PB-4 fully extended and the lens set to the closest focus distance the reproduction ratio is 3:2 or 1.5 times life size. If needed the lens can be reverse mounted on the PB-4 using the Nikon BR2 or BR2A reversing adapter, which it fits directly, owing to its 52mm filter thread size.<\/p>\n Thus the combination of Micro-Nikkor without or with the Bellows PB-4 gives you a continuous focusing range from infinity to 1.5 times life-size. Nice.<\/p>\n The above image also shows the subject to lens distance at the closest focus distance, which is 11″ with the lens hood retracted, making proper lighting a simple matter.<\/p>\n So this is a handy combination of a state-of-the-art bellows with a tack sharp macro lens. Some images to come, later.<\/p>\n To keep weight down I removed the tripod collar from the Micro-Nikkor. It also bears adding that this is not a lightweight rig so a solid tripod<\/a> with broadly splayed legs and a heavy duty ball head<\/a> are called for.<\/p>\n","protected":false},"excerpt":{"rendered":" A handy combination.
