This standard zoom lens smoothly transitions from wide angle to short telephoto focal lengths equivalent to 35.5mm to 67mm in a 35mm format. Through the zoom range, it maintains a constant f/4.5 maximum aperture and can stop at f/32. It uses a 3-group zoom system for providing high delineation performance that is stable over the entire zoom range. It offers a minimum shooting distance of only 0.5m. The AF/MF operation can be performed quickly by simply sliding the entire focus ring forward or backward, while the manual focus operation can easily be altered after AF to allow for fine focus adjustments. As well, an eight-blade diaphragm creates even out-of-focus areas in images. a beautiful, soft bokeh effect.

 

This is an easy-to-use zoom lens based on the standard range that is suitable for regular usage. It uses a 3-group zoom system for providing high delineation performance that is stable over the entire zoom range. The minimum shooting distance is only 0.5m for enabling closeups of subjects by using the wide angle and also enjoyment of shooting that emphasizes perspective. Also, because the open F value is fixed at all focal lengths, this is useful for manual exposure. AF/MF switching is performed quickly by simply sliding the entire focus ring forward or backward. A large flower-shaped hood is provided for effectively preventing ghosting and flare.
