Kurtmunger reviews the Konica Minolta AF 28-75mm f/2.8 and writes;
“The Konica Minolta AF 28-75mm F/2.8 lens performs very well in the centers at all focal lengths and apertures. Color fringing, coma and light fall-off are almost non-existent. There are some drawbacks to consider; the corners need to be stopped down for maximum sharpness…”

Suprising quality for the price | Rating: ★★★★☆
“Well-built lens. It provides excellent sharpness (after I sent my 7D in for an autofocus issue) even wide-open and has reasonably fast focusing. The zoom ring is a lot stiffer than my old Maxxum lenses, but is smooth and the barrel doesn’t creep when the camera is pointed down..” – by D. Pierce

Excellent quality for reasonable price | Rating: ★★★★★
“The 2.8 coupled with the antishake of the minolta 5d or 7d makes for some of the best handheld low light photography available anywhere. Focus is quick, photos are crisp, zoom is smooth.” – by A. Burmester

A seriously good lens. | Rating: ★★★★★
“This is an awesome lens. It’s small and light. The zoom and focus rings have excellent grip and have very smooth operation. The build feels solid. Autofocusing with this lens is extremely fast and accurate. Autofocus operation is also the most silent of all my lenses. This lens is also razor sharp! If you are looking for a constant aperature zoom lens in this range look no further! “ – by M. R. Noronha

About the Dynax Lens System

* Aspherical Lenses: Minolta retains a distinct advantage in the use of aspherical optics. With ordinary spherical lenses, the focal point varies according to whether the incident light passes through the central or peripheral part of the lens, thus producing spherical aberration. While perfect compensation has never been achieved, and is particularly difficult to compensate for in large diameter lenses, decreasing the lens curve or combining dispersion lenses are methods commonly used in an attempt to compensate for spherical aberration. Minolta’s aspherical lenses are developed not only to correct spherical aberration in large-diameter lenses, but also to take high-contrast images with less blotting effects while in the largest aperture. Minolta’s aspherical lenses are effective in correcting distortion while using wide and standard zooms. What’s more, the use of aspherical lenses decreases the total number of lenses required to produce a complete lens.This technology has enabled Minolta to create more compact lenses.
* AD Glass: AD (Anomalous Dispersion) glass decreases chromatic aberration more than normal optical glass, to prevent a decrease in resolving power which occurs when the focal length increases. The unique AD glass developed by Minolta enables vivid reproductions when using large-diameter telephoto lenses and telephoto zoom lenses.
* Circular 7- or 9-Blade Aperture: The closer the aperture shape is to becoming a perfect circle, the more beautiful your defocused effect will be. That’s why Minolta’s specially designed aperture blades produce a circular opening from their widest setting down 1.5 steps to help smooth a scene’s out-of-focus areas. When you take a picture with sunlight shining through foliage, a picture at sunset or a picture of neon lights, the source of the light can be defocused beautifully. The number of aperture blades must be maximized to make the aperture as perfectly circular as possible. Conversely, each blade can be curved to produce a circular aperture, and thus a desired blurring effect.
