from Adorama Summary:Beautiful lens, this is the heaviest I own so far, the front glass is 72mm and the glass is almost the 72mm, back end lens is also bigger then any of my previous lenses (nikon 18-200 vr, nikon 35mm f.18, tokina 116 F2.8) , it's heavy but not to long, making it very balanced and allowing me to take hand held photos at 1/250 with no blurriness. The autofocus is precise and I found it not slower or less precise than any of my other lenses. This is so far the sharpest lens I own, I have compared 100% crops from the 18-200 VR lens at F8 and the sigma 150 is noticeable sharper, nothing scientific, just my evaluation.
Using the focus ring for manual focus is a pleasure, it is slow, smooth and precise, it reminds me of the old lenses I used in the film cameras back in the 80's.
The tripod ring that comes with the lens is fantastic, I have a cheap tripod an it helps me level the camera, it is designed to have a perfect balance between the lens weight and the camera weight ( Nikon D300), also makes it very easy to remove or reinstall the camera on the tripod. Bokeh ? very very smooth better than my 35mm at f1.8.
The lens says it is F2.8, it was a bit of surprise to me that F2.8 is only valid when focused at infinity, the max aperture becomes smaller as you focus closer being it F5.6 at the closest focusing distance. But ... it doesn't really matter, F2.8 at 150mm focusing at 0.38 meters gives such a shallow DOF that I think it is unusable, I found my self using F11 to F32 when shooting macro.
I've been shooting in "Neutral" mode, and getting beautiful colors and contrast, whereas other lenses usually get a bit of a washed out image and contrast has to be improved in Post Processing. Strengths:Sharp, very sharp
F2.8 at infinity
Beautiful bokeh
Nice smooth manual focus
Autofocus speed similar to my other AFS lenses Weaknesses:Perhaps a bit pricey compared with other non major brand macro lenses, but who else does 150mm at F2.8 ? Similar Products Used:I have taken "macro" images with the 18-55, 35mm , 200mm lenses although none of these are a real macro lens , the quality of the image and level of magnification of the sigma 150mm is way better. Customer Service:not used
