Sigma 150mm f/2.8 EX DG HSM APO HSM IF Macro Lens for Nikon SLR Cameras Customer Reviews
I have the Nikon 60 Micro lens and wanted something with more working distance. In the Photozone.de test, it was amazing. Very high resolution, even at f/2.8. And very low CA's(chromatic abberations). So I bought it and does it deliver that kind of performance? Yes it does! Sharpness and color redention was stunning. And at 1:1(life size on the negative or digital sensor), there's more than 7 inches working distance. Build quality is excellent. It's mostly metal construction. The focus ring has a nice dampened feel to it. The new Sigma rear caps fit tighter and do not come off. But they're a little harder to mount. About autofocus performance, it's fast, but hunted in low light with the Nikon D50 while shooting motocross. But that's a weakness of the camera body, not the lens. On the F100(a high end Nikon film camera), it was lightning fast and dead on. Yes it is a full frame lens, so it can be used on 35mm cameras also. There's a tripod collar and it makes for a well balanced setup when on a tripod. The collar is removable making it easier to do handheld shooting. The maximum aperture of f/2.8 allows more flexibility in low light. The filter thread is 72mm, and filters this big get expensive. It is a good all around telephoto-sports, portraits, landscapes...you name it. Just because it's labeled a macro doesn't mean a lens is good for macro only! It's not cheap, but if you want a solid performer that's great for all occasions, this just may what you're looking for....By Sigma gets an A on this one.
