Sigma 18-50mm F2.8 EX DC

Review Date: Feb 22, 2008 Recommend? yes | Price paid: Not Indicated | Rating: 9 

Pros: Very Sharp above f4, f2.8 works well at all focal lengths, Good Bokeh at 35mm+, Low Distortion above 24mm, New quiet/fast HSM motor, Can focus almost touching glass, near-macro @ 1:3, Heavy build quality
Focus ring moves during AF, Moderate distortion at 18-24mm, Soft (but not bad) @ f2.8, Front cap cannot be attached with hood on

I love this lens, it and it's 150mm Macro brother are the only lenses I need.

Fast and quiet HSM, near-macro close focus, high resolution contrasty images, and VERY sharp above f4. The distortion is moderate below 24mm and undetectable above 35mm. The bokeh at 35mm+ is great at large aperatures. And it feels well built, no zoom creep and good focal dial resistance.

But what the hell were Sigma thinking having the focus ring move during AF? A lens this short and heavy requires you to grab the damn ring to hold the camera and when the ring moves you lose shots. And Sigma needs to start using center-pinch lens caps, you can't attach their cap with the hood on.

Otherwise a GREAT kit type standard/wide zoom for digital cropped cameras. Highly recommended!

Sigma 150mm f2.8 APO Macro DG EX HSM

Review Date: Dec 22, 2007 Recommend? yes | Price paid: $425.00 | Rating: 10 

Pros: Build Quality, Great Bokeh, 1:1 Macro, Excellent IQ, Quiet AF, No Distortion, Exceptional Value.
Some Hunt and Search on Auto-Focus under low light and Macro.

Probably the best value for Nikon dSLRs. This lens has to be consider almost pro-grade. It's built like a tank, and the picture quality is exceptional.

Extremely sharp, great IQ, smooth bokeh, and full 1:1 macro.

The only small problem is the AF motor hunts under low light and macro circumstances--you'll probably need to use MF at this focal length for macro anyway.

If is wasn't for the telephoto focal length I'd leave it on my camera full time. It is simply the best lens I probably ever use that'll cost me under $1000.
