Bower SLY2414OD
The f/1.4 maximum aperture and two aspherical elements deliver strong low-light performance and reduced spherical aberration, while the AE chip enables auto exposure and focus confirmation despite being manual focus only. Multi-coated optics minimize flare and distortion, and the 8-blade diaphragm produces smooth background blur for subject isolation at the 48mm equivalent field of view. This lens suits Four Thirds portrait photographers who want a fast prime with hands-on focus control and automated exposure for shallow depth-of-field work.
