(G): G-Series Lenses

G-Series AF lenses stand out for the distinctive level of image quality and photographic performance they provide serious photographers. Circular aperture design, double-floating and floating focusing systems, AD (Anomalous Dispersion) glass, aspherical lens elements and a focus hold button, are advanced G-Series design features that help produce a unique soft and natural defocusing effect, as well as enabling you to take truly high quality photos with the sharpness and vividness you expect.

SSM (Supersonic-wave Motor) Lenses

The supersonic-wave motor uses a piezo-electric system, which causes components to change shape when voltage is applied. Compared to conventional DC motors, the supersonic-wave motor has characteristics, such as producing high torque from slow rotation and providing quick start and stop responses, that make it the ideal form of lens drive, . By employing this motor, the SSM lenses provide ultra-quiet, ultra-smooth and superior AF operation.

(D): Designates lenses with integrated Distance Encoder to support ADI flash metering.

All lenses designated with "D" enable the use of the sophisticated ADI flash metering (Advanced Distance Integration). By comparing the information from pre-flash metering with data given by the Distance Encoder, the ADI metering calculates the settings for perfect image illumination - even when the subject is located in front of a very dark, very bright or reflective background.

In combination with the Dynax 7D, 5D, 7, 60, 40, 5, 4 or 3L, (D)-lenses enable ADI flash metering (Advanced Distance Integration) when a Program Flash 2500 (D), 3600 HS (D) or 5600 HS (D) is used with the camera

(APO): Apochromatic Lenses

Lenses with the endorsement "Apo" indicate a very high level of quality. When the rays of light go trough the lens, the different wave lengths (colours) are refracted differently. Shorter wave length (blue) are refracted more than longer wave lengths (red). This means that there are different focal points for each colour. Thanks to the apochromatic correction, chromatic aberration is corrected for the wave lengths (colours). (Usually just two wave lengths are corrected.) The result its high contrast and a precise reproduction of fine detail. Especially used with tele lenses, this correction delivers brilliant image Quality.

(ASP): Aspherical Lens

Konica Minolta retains a distinct advantage in the use of aspherical optics. With ordinary spherical elements, 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. Konica Minolta’s aspherical lenses are developed not only to correct spherical aberration in large diameter lenses, but also to maintain high contrast even at the largest aperture. Konica 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 elements required to produce a complete lens.This technology has enabled Konica Minolta to create more compact lenses.

(AD): AD Glasss

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 Konica Minolta enables vivid reproductions when using large diameter telephoto lenses and telephoto zoom lenses.

(CIR): 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 Konica Minolta’s specially-designed aperture blades produce a circular opening from their widest setting down 1.5 stops to help smooth the out-of-focus areas of a scene . 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. Additionally, each blade can be curved to produce a circular aperture, and thus the desired defocusing effect.

Anti-Shake compatible

The established Anti-Shake-System is integrated into the body of the DYNAX 5D. Therefore almost every Konica Minolta AF lens is suitable for the new digital SLR camera. You can shoot with up to three shutter speeds slower, without having to buy expensive special equipment.
