9 out of 10 points and recommendedSharpness, Bokeh, Construction and SizeNo AF-S
Wanted a smaller 70-200 f2.8 type lens and this one felt like a good compromise. The range 50 to 135 suits me better for general photography and portraits, this thing doesnt scare people because it doesnt look big. The 50-135 is compact, very well made and doesnt extend, also it has very good sharpness wide open and renders a very good Bokeh through out its zoom range. Handling it is very pleasant and the rings are damped the only real down side i find to the lens is the lack of AF-S if you need very fast focusing. The tripod collar doesnt bother me personally.reviewed August 30th, 2010 (purchased for $550)
Can be a little prone to flair but the hood is good.
Over all its very good and its my portrait machine for my Nikon d300,
