Modes

In the case of ZK lenses, the f-stop can either be set manually GB using the lens aperture ring or, alternatively, using the camera

body (by locking the lens aperture ring to position „A“); this depends on the required mode (aperture priority, shutter priority, programmed exposure or manual exposure setting) and the features of the camera body in each case.

For more information on available modes with manual lenses (Pentax KA standard), please consult your camera‘s operating instructions.

Depending on the features of the camera body, the ZS lens can be used either with full aperture metering or stop-down metering. For full aperture metering, select the desired f-stop using the aperture ring and switch the selector lever on the lens to position „A“.

When using a ZS lens on a camera body without aperture transfer or with an adapter, lock the lens aperture to the pre- selected value by switching the lever to position „M“. With many cameras, it is then possible to carry out automatic exposure with aperture priority.

Tips for lens care

To avoid any imperfections and humidity on the front lens sur­

face, and for general protection, it is recommended to use the GB lens cap as much as possible when the lens is not in use. Dust, smudges and fingerprints on the lens surface can be gently removed with a very soft brush and then with a dry, clean,

soft cotton cloth. The ZEISS lens cleaning kit will give superior results and is highly recommended for this purpose.

The ZS lenses incorporate advanced optical designs that are engineered to minimize distortion, chromatic aberration, and flare, delivering sharp images with stunning clarity.

Moving to the ZF-Mount, this mount is crafted with serious photographers in mind. The ZF lenses are predominantly manual focus, appealing to purists who appreciate the control that manual photography offers. These lenses feature robust metal constructions that not only enhance durability but also give a premium feel. The optical excellence of ZF lenses is evident, characterized by their ability to produce beautiful bokeh and excellent low-light performance thanks to fast maximum aperture designs. Photographers love the tactile experience provided by the smooth focusing mechanism and well-damped aperture rings.

The ZK-Mount variants, on the other hand, bring autofocus capabilities to the table without sacrificing the quality Pentax is known for. These lenses are optimized for digital sensors and often come with advanced coatings to reduce ghosting and flare when shooting in challenging light conditions. Notably, the ZK line includes a range of zoom and prime lenses, catering to different focal lengths for various photography styles, from landscapes to portraits.

All these mounts and lenses demonstrate Pentax’s commitment to optical innovation. The company incorporates weather-sealing technologies in many of its offerings, allowing photographers to venture into challenging environments without the worry of equipment failure due to the elements. This ruggedness, combined with superior optical design and build quality, sets Pentax apart in a competitive market.

In summary, the Pentax ZS-Mount, ZF-Mount, ZK-Mount, and their respective lenses represent a harmonious blend of technological advancement and thoughtful design.
