Pentax SMC DA 18-55 mm f/ 3.5-5.6 AL II Lens Manuale

Main Features  

In its 15-element, 11-group optics, this zoom lens 

incorporates two high-precision aspherical optical elements, 

one ED (Extra-low Dispersion) glass optical element and 

one anomalous-dispersion glass optical element, to deliver 

bright, sharp images with minimal chromatic and spherical 

aberrations. Since its optics is designed to assure ample 

resolving power for the large, high-pixel image sensor, it 

produces well-defined, fine-detailed images.

This standard zoom lens accommodates the image circle 

of a 35mm full-frame image sensor, and covers focal 

lengths between 28mm wide angle and 105mm medium 

telephoto. By incorporating the latest optics and a number 

of high-performance optical elements, it retains a sufficient 

brightness  level  even  at  edges  of  the  image  field,  while 

effectively compensating for various aberrations. It delivers  

high-resolution images by optimizing the imaging power 

of the PENTAX K-1’s approximately 36.4 effective 

megapixels. Its compact, lightweight body and excellent 

cost performance make this lens a perfect regular lens for 

the PENTAX K-1.

This lens features a dependable weather-resistant 

construction with eight sealing parts to effectively prevent 

the intrusion of water into the lens interior. Paired with a 

weather-resistant PENTAX digital SLR camera body, it 

creates a durable, dependable digital imaging system that 

performs superbly in demanding shooting settings — even 

in rain or mist, or in locations prone to water splashing or 

spray.

This lens is treated with the high-grade, multi-layer 

HD Coating.* Compared with conventional multi-layer 

coatings, this PENTAX-original coating assures higher light 

transmittance  and  less  reflection  to  deliver  bright,  high-

contrast  images  that  are  free  of  flare  and  ghost  images, 

even under demanding lighting conditions such as backlight.

* HD stands for High Definition.

This PENTAX-developed system allows for flawless, delay-

free switching from autofocus to manual-focus operation, 

after the subject is captured in focus by the camera’s AF 

system.

 

• 

SP (Super Protect) Coating applied to the front 

surface of the lens to effectively repel water and 

grease.

• 

Rounded diaphragm to produce a smooth, beautiful 

bokeh (defocus) effect, while minimizing the streaking 

effect of point light sources.

• 

Built-in DC motor to assure smooth, quiet, high-speed 

autofocus operation.
