The Leica 75mm f/2.0 APO Summicron M Aspherical lens is a fast high-performance lens that is also extremely compact.

With its more natural perspective compared to a 90mm focal length, it is ideally suited for many applications including reportage and portraits – particularly in smaller rooms. Its small dimensions result in not only outstanding handling but also a Leica M viewfinder image that is almost completely free of shadowing, thus allowing totally undisturbed viewing of the subject.

This lens has been updated with the “6-bit” coding, which allows the digital M camera to read this information optically and to identify which lens is being used. The camera can then (optionally) apply a “final stage” software based vignetting correction (for RAW images the lens used is simply recorded, no change is made).

Optical improvements include: an aspherical surface, glass with anomalous partial dispersion and a high refractive index, a floating element including a brand new, high-precision adjusting mechanism, lens coating, and sophisticated measures to reduce internal reflection.

The Pentax SMCP-DA* 50-135mm f/2.8 ED (IF) SDM Autofocus Lens is a high-quality telephoto zoom lens that is designed for exclusive use with Pentax digital SLR cameras. It offers a focal length that is equivalent (in 35mm format) from 75mm to 202mm. This wide coverage is ideal for a variety of telephoto applications, including portraiture, sports and scenery.

The image circle in DA-series lenses is designed to perfectly match the 23.5mm x 15.7mm size of the CCD used in Pentax digital SLRs to optimize camera performance.(*) This design also contributes to a drastic reduction in size, weight and production cost, compared to 35mm-format counterparts with similar specifications.

Pentax DA* (DA-Star) zoom lenses come equipped with the SDM System, which assures smoother, quieter auto-focusing operation by using a built-in supersonic motor. When mounted on the K10D digital SLR camera body, the focus mode is automatically switched to SDM-assisted auto-focusing. When mounted on older Pentax digital SLR camera bodies, the conventional autofocus mode using a camera-mounted motor is selected.
