positive:+ amazing color & bokeh
+ the 100-300 reach
+ built rock solid (except the hood)
+ BLACK (hate white lenses)
negative:- slow AF in low light
- lens hood feels cheap, and doesn't always seat well (especially when reversed)
- lens cap constantly popping off
comment:Built like a tank, and in the right light takes amazing pics. The bokeh and color just blow me away. Sharpness is fantastic in perfect light ... just a touch less than my Minolta 28-70 G.


In less than ideal lighting, this lens falls down a little...but hey, it's F4 : ) I am a little less than perfectly pleased in hazy and overly bright situations - the colors get muted and washed out...somewhat non-distinct IQ as well.

I have also noticed this lens will focus lock when I'm closer than the min focusing distance, but result in a crap shot - well, duh. Kinda wish it wouldn't lock, as I'm not always paying attention to how close I am.

When compared to my SAL75-300 ... well, there is no comparison. Gave the lens away after getting this.

I would love to have an F2.8 in this range. 200mm is just too short for the kinds of pics I use this lens for (I spend most of my time at 170-250) and I don't want to pop for the Sony or Minolta using a TC.

I've only had the lens for a couple months, and for now I'm pretty pleased.


(2010 update)...
A bit under 2 years with this lens and I'm still a happy camper. At times I get 2.8 Envy but I don't regret making this purchase. When comparing the images this lens produced vs. my Minolta 28-70 G it seems more 'natural' ... if that is the right term. To my eyes, the minolta G lenses produce a magical image ... almost other wordly in their perfection. The Sigma is more relaxed ... more 'as I remember it'. It's hard to put my finger on it, but think one area is sharpness ... the Minolta / Sony G lenses reveal detail more sharply. I love the richness of the color, and the bokeh of this lense and don't feel that I'm missing anything. At $900 vs. the $1500 ~ $1700 I could have paid for the various Sony options ... I can't hesitate for a moment to recommend this lens and would buy it again.
