Highlight

• A standard focal length 50-millimeter lens is effective in a multitude of shooting situations and ideal for day-to-day shooting.
• Elements/groups: 7/6, diaphragm: blades 8, filter thread: font 58 millimeters. Minimum focusing distance: 17.8 inches.
• An f/1.4 maximum aperture provides clear imaging in low-light situations and shallow depth of field.
• Ultrasonic autofocus motor (USM) operation is fast, smooth, and virtually silent
• 2 high-refraction lens elements and new Gaussian optics eliminate astigmatism and suppress astigmatic difference.
• This large aperture standard prime lens has superior peripheral brightness even at the maximum aperture.
• Lens construction: 8 elements in 6 groups, filter size: 77 millimeters
• Optimized for digital – super multi-layer coating minimizes flare and ghosting – a common problem of digital cameras
• The optimum optical design and molded glass aspherical lens elements provide excellent correction for all types of aberrations, including coma aberration, resulting in superior optical performance
• The hypersonic motor (HSM) ensures silent, high-speed auto-focusing as well as full-time manual focusing capability.
