Compatible with Sony E-mount
Equipped with electronic contacts, the lens usage status is reflected in the Exif information of the shooting data. In addition, since it has a built-in distance encoder, it supports 5-axis image stabilization on the camera body. It is also possible to enlarge the viewfinder by operating the focus ring.
Optimized Optical Design
In addition to ensuring a full-size image circle, the optical design is optimized for Sony E-mount sensors, maintaining high resolution even at the edges of the screen and suppressing phenomena such as color casting.
The minimum shooting distance is 0.28m
The minimum shooting distance from the subject to the imaging plane is 0.28m. The perspective unique to a wide-angle lens and the maximum aperture of F1.5 enable images with shallow focus, especially in close-up areas.
Beautiful bokeh with 12 aperture blades
A 12-blade aperture is used to make the aperture shape closer to a circle, resulting in natural depiction of out-of-focus areas and soft bokeh of point light sources rather than polygonal shapes.
Manual focus for precise focusing
The all-metal helicoid unit is machined and adjusted with high precision, and the use of high-quality grease that produces just the right amount of torque makes focusing feel smooth and allows for subtle focus adjustments.
Aperture click switching mechanism
The aperture click switching mechanism allows the aperture ring to be opened and closed steplessly without making a clicking sound. This eliminates the need to worry about the sound of the aperture ring being picked up during video recording, and also enables precise depth control by fine-tuning the aperture ring.
