Style name: Regular product introduction STM is an abbreviation for Stepping Motor. Used to drive the focus lens. Correction of spherical aberration for large-diameter lenses, distortion aberration correction for wide-angle lenses, and miniaturization of zoom lenses. The aspheric lens was born to solve these three themes. This function enables manual focus immediately after rotating the focus ring after one-shot AF so that the photographer can finally adjust the focus after autofocus. From Discovery Japan [Features] Diameter 68.2mm, thickness 22.8mm, weight about 130g. EF lens is the thinnest and lightest pancake lens. By adopting a stepping motor (+ gear), lens miniaturization, silent &
high-speed autofocus are realized. More comfortable video recording. The shortest shooting distance is 0.3m and the shooting magnification is 0.18x. A beautiful bokeh is achieved by using a circular aperture. The compact design makes it easy to take snapshots, and it is also effective as a lens that can be taken without giving a sense of pressure when shooting people. * When the AF operation of the camera is set to [One-shot AF], you can adjust the focus arbitrarily by turning the focus ring with the shutter half pressed after the AF operation is completed. Also, manual focus cannot be adjusted during power off, auto power off, or standby. ■
STM STMSTM is an abbreviation for Stepping Motor. Used to drive the focus lens. There are two types of STM, a lead screw type with excellent quietness and smoothness, and a gear type that prioritizes miniaturization, and features quiet and smooth drive *. * In combination with EOS Kiss X6i (as of June 2012) ■
Aspherical lens Aspherical lens correction of spherical aberration of large-aperture lens, distortion correction of wide-angle lens, and miniaturization of zoom lens. The aspheric lens was born to solve these three themes. ■
Full-time manual focus Full-time manual focus After auto-focusing, this function enables manual focus immediately after rotating the focus ring after one-shot AF so that the photographer can finally adjust the focus.
