comment:This is a fast and sharp 300mm F/4 lens.

AF is faster than both Tokina 400mm and Sigma 400mm APO non-macro lenses on Sony A200. The IQ is better too. 1.4 TC can be used to make it a 420mm f/5.6 AF Macro lens and this is the reason why I only compared this lens with 400mm lenses. It seems that the sharpness and AF were not significantly affected with 1.4x TC. It did hunts a lot with 2x TC and the IQ was degraded but it became a 600mm f/8 lens.

This lens is so much alike the renowned Sigma 400mm APO Macro lens in terms of IQ, looks, and construction. To me it is as good if not better because it provides more mobility and flexibility. Unlike Sigma 400mm APO Macro lens which is longer and heavier (even heavier than Canon EF 400mm L) this lens give you the convenience of light traveling and easy conversion to a 420mm f/5.6 with 1.4 TC.

Even though the lens is rarer than Sigma 400mm Apo Macro it is always priced lower. Grab it if you can find one at reasonable price.
