7 Artisans 18mm F2.8 Auto Focus UMC II Full Frame Macro 鏡頭 商品介紹
A refined wide-angle prime, the 28mm f/1.4 from 7artisans Photoelectric offers both a flexible field of view along with a fast design. The bright f/1.4 maximum aperture offers increased control over depth of field and also suits working in difficult lighting conditions. Complementing this is an advanced optical design that includes aspherical, high refractive index, and extra-low dispersion glass elements to control a variety of aberrations for increased sharpness, clarity, and color accuracy. A multi-layer coating also contributes to reducing flare and ghosting for improved contrast when working in bright and backlit situations. Balancing the optical merits, this lens's manual focusing design affords a 2.3' minimum focusing distance and a 13-blade diaphragm contributes to a pleasing bokeh quality.
