In celebration of Tamron's 40th anniversary of the SP lens series, the SP 35mm f/1.4 Di USD has been created to showcase their lens-making capabilities. This flexible wide-angle prime is ideal for gen espandi...eral shooting applications, ranging from street photography to event shooting, and its impressively bright f/1.4 maximum aperture excels in difficult lighting conditions and offers increased control over depth of field. The optical design incorporates a series of low dispersion and aspherical elements, which control a variety of aberrations in order to achieve high image clarity and sharpness. A BBAR-G2 coating has also been applied, and helps to reduce flare and ghosting for improved color and contrast when working in strong lighting conditions.
