I have the Konica Minolta AF 28-75mm F/2.8 (D) review ready. This lens produces sharp centers, even at F/2.8, but the image periphery is soft unless stopped down hard, especially on a full frame camera. If you’re using an APS-C body, you might consider the Sigma 18-50mm F/2.8, which would give a better zoom range in my opinion, and may give better results depending on: Sigma quality control, which is bad, if you buy one, plan on sending your lens back to get it corrected. I’ve sent all but one Sigma back at least once, and they’ve corrected the problems (usually sharpness) quickly. For full frame users, the same story, but slightly worse. If you only care about the central area of the image, this lens is very good, and is better at flare and ghosting control than the much more expensive Minolta AF 28-70mm F/2.8 G just tested.
