It is only a couple of inches long. It can focus as close as 1 foot with the adapter that comes with it, which gives it a macro of 1:1:8. The downside is that it is manual focus. In a world where some cameras, with autofocus lenses, can pinpoint the eye automatically and focus on it, it seems out of date. As with any 90mm Lens, the depth of field is narrow so when I shoot I expect that many of the images I capture on the street will miss the focus, the shots are not planned and everyone is moving, including myself. I shot these images with the Nikon Df, most with an aperture of 5.6 and a shutter speed of 1/1000.
