Phase One XF 120mm Macro lens

The 120mm LS is a hefty lens, even for medium format. It measures 4.4 by 3.3 inches (HD) and weighs 1.8 pounds. The barrel extends significantly as you focus close, nearly doubling in length when working at 1:1 magnification. The lens barrel is metal and a large. A reversible lens hood is included, but the front element is so far recessed that you can get away without using it. The exception would be if you're using a front filter (the lens has an 86mm thread), as the hood will reduce the chance of light hitting it at an odd angle.
