Great for landscape, street, and general photography
Excellent low-light performance and depth-of-field control

Superlative build and image quality
Fast f/1.4 Aperture Semi-Wide Angle. The fast f/1.4 aperture is great in low light, and keeps you shooting everywhere between the dim and the dark. The fast aperture also enables moderately wide-angle images with a shallow depth of field. The 35mm focal length has long been a staple for landscape, street, and all-around general photography. Using an APS-C camera? This lens will give you a 56mm-equivalent focal length.
Ring-Type USD Autofocus System. An Ultrasonic Silent Drive motor provides fast, precise, and quiet autofocus performance. It also enables full-time manual focus control without having to shift into a dedicated manual-focus mode.
Higher Quality Standards. The 35mm f/1.4 joins Tamron’s prosumer SP (Super Performance) line, meaning that it features improved build and image quality over previous Tamron lenses.
