For a kit lens with the D90 I couldn't believe the sharpness of the images, while wide open there is corner softness on most focal lengths, stopping down to f/5.6 at the wide end fixes most of the this.reviewed April 10th, 2009 (purchased for $320)
I found the sweet spot for my lens was at f/8 with center sharpness being somewhat sharper at f/5.6 from 35-70mm, however at f/8 the frame is sharp all over.
- Noticeable vignetting at wide end
- VR works well enough for me that i can get 7 out of 10 shots sharp at a 1/2 sec exposure handheld @ 18-50mm
- Compared to the 28-105mm f/3.5~4.5D IF it is slightly sharper at all focal lengths, That being said the images become almost the same in terms of sharpness when you get to f/8-f/10
I took this lens to an Airshow while the 105mm is just barely enough for take off and landing shots the shots that i did take surprised me for a non prime lens. I will most likely hold on to this lens until i get the 16-85mm VR,
Also I used this lens on the D90 I do not know performance on other cameras.
