smc PENTAX-FA 31mmF1.8AL Limited
The ultra-fast smc PENTAX FA 31mm f/1.8 Limited is the wide-angle lens of choice for those who appreciate engineering mastery, as well as masterful image reproduction. It features outstanding sharpness and clarity, in a compact all-metal housing that characterizes all PENTAX Limited lenses.
Focal length of 31mm
This lens provides sharp imaging, strong sense of perspective, large depth of field, and other exceptional characteristics for sharp, crystal-clear images in a general wide lens, and also incorporates abundant gradations, detailed reproduction of dark shades, and natural, soft out-of-focus (bokeh) effect called "imaging flavors".
This lens uses a "floating lens system" where the space between a portion of the lens system is changed based on the shooting distance for correcting the various types of aberrations that occur at all shooting distances.
A focal length of 31mm is used, which is almost exactly midway between the 35mm and 28mm standard wide lenses. This provides a unique angle of view that can draw out the best points of each focal length based on how the shot is framed.
High imaging performance and stunning expressive capability
Floating lens system
Machined aluminum lens barrel to optimize the texture of the material
A large aperture and a compact, lightweight design simultaneously achieved to defy conventional performance evaluations
Exclusively designed lens hoods and slip-on caps to match the character of individual lenses
Every lens barrel and all exterior components of the PENTAX Limited-series lenses are meticulously machined from high-grade aluminum material to optimize the high-quality visual design and the feel when the photographer touches them.
With FA Limited-series lenses, however, PENTAX has succeeded in achieving these two contradicting goals simultaneously, by making them compact and easy-to-handle through effective control of aberrations, while optimizing the sense of depth and sharpness in resulting images.
The lens hood eliminates the need for a reversal of position when the lens is stored, and also lets you start photographing immediately simply by removing the cap from the front end of the lens.
