Product Description

From the Manufacturer

A versatile zoom lens with bright imaging at any focal length. Features a circular iris with excellent defocusing characteristics, and Advanced Distance Integration (ADI) for enhanced flash shooting performance.

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.

Don't know what happened with the guy below, sounds like he got a lemon. You won't get a better lens in this range for the minolta without finding one of the older G lenses that costs about three times as much. 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.

This review is from: Konica Minolta AF 28-75mm f/2.8 Lens for the Maxxum 5D & 7D Digital SLR Camera (Electronics)

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. A fair trade. I use it as a people lens at family gatherings and wedding receptions where it's f2.8 constant maximum aperture works well with the camera's stabilization to keep flash usage to a polite minimum. I took a star off only because I wish the wide end was 24 mm instead of 28.

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!
