tozoA compact and lightweight standard zoom lens for use with PENTAX K-mount reflex cameras. Its image power and ease of use make it the perfect companion for the new PENTAX K-1.

Despite its compact and manageable body, this versatile zoom is designed to accommodate the image circle of a full-frame 35mm image sensor, thanks to cutting-edge optical techniques and high-performance optical elements. Mounted on a Pentax K-1 camera, which offers high-resolution imaging power, it becomes the ideal lens for daily use for this new full-frame camera.

Main characteristic

Standard zoom that covers the most used focal lengths

This standard zoom lens covers the image circle of a 35mm full-frame image sensor, and covers focal lengths between 28mm and 105mm, from wide-angle to medium telephoto. By incorporating the latest optical technology and a series of high-performance optical elements, a sufficient level of brightness is achieved, even at the edges of the image, and various aberrations are effectively compensated. It provides high resolution images by optimizing the image power of the approximately 36.4 effective megapixels of the PENTAX K-1. Its compact and lightweight body and excellent value for money make this the perfect ally for the PENTAX K-1.

Excellent image description, which completes the performance of the full frame digital SLR camera

In its 15-elements, in 11-optical groups, this zoom lens incorporates two aspheric elements of high precision, an ED element of low dispersion (Extra-low Dispersion) and an optical element of anomalous dispersion, to offer bright and clear images with minimal chromatic and spherical aberrations. Its optics are designed to ensure high resolution images, defined and detailed and exploit the potential of large image sensors.

HD coating for a better image description

This lens is treated with HD multilayer coating. * Compared with conventional multilayer coatings, this original PENTAX coating allows high light transmission and fewer reflections, to provide contrast-free images of ghosting and ghosting, even in adverse situations such as backlighting.

* HD is synonymous with High Definition.

Focus system Quick-Shift Focus

This system, developed by PENTAX, allows a quick change from the autofocus system to manual mode, once the subject has been focused by the AF system of the camera.

Weather resistant construction

This objective has a reliable weather resistant construction thanks to its 8 sealed parts that prevent the objective of the entrance of water in its interior. Together with a weather-resistant PENTAX camera, a reliable and durable assembly is created, to be able to shoot safely in any situation - even in rain or fog, or in adverse locations.

Other features

· SP (Super Protect) coating on the front surface of the lens to repel water and oil.

· Circular diafragama to produce a soft effect of defocus (bokeh) and to prevent the rays produced by points of light.

· Built-in DC motor for fast and silent focusing.
