A photographer by the name of Nasim Mansurov has a terrific extended review of the new Nikon 16-35mm f/v VR lens here. Why I am pointing out this particular review, is Mansurov really goes into depth around how the lens handles, how it focuses, how it compares to other lenses of a similar type and how the vibration reduction works. He also talks about bokeh and vignetting, ghosting and flaring. The he does some actual sharpness tests. You can learn a lot from Mansuro’v review and not just about this particular Nikon lens as what he has to say applies to all lenses.
