Prime standard-length lens
designed for full-frame Sony E-mount mirrorless cameras, however, can also be
used on APS-C models where it provides a 75mm equivalent focal length.
Bright f/1.4 maximum aperture
offers control over depth of field and suits working in low-light conditions.
Newly designed HLA
(High-response Linear Actuator) focusing motor provides unprecedented
high-speed, high-precision, and quiet AF.
Based on the latest optical
design technology, the lens incorporates 14 elements in 11 groups, with 3 aspherical
lenses and 1 SLD glass element. The lens effectively suppresses various
aberrations such as astigmatism and field curvature, which cannot be corrected
in-camera.
Equipped with a focus mode
switch, an aperture ring click switch, an aperture ring lock switch to prevent
unintended operation, and an AFL button to assign any function from the camera.
Rounded 11-blade diaphragm
contributes to a smooth and pleasing bokeh quality when employing selective
focus techniques.
Front lens element has been treated
with a water- and oil-repellent coating to benefit working in harsh
environmental conditions.
Dust and splash-resistant
construction with a brass bayonet mount for ensured accuracy and
durability.
Covering ultra-wide to wide focal lengths, this lens is particularly
suitable for landscape, astrophotography, and architectural shooting.
Its bright f/2.8 constant
maximum aperture complements this range and affords increased control over
depth of field along with enhanced low-light performance.
The optical design incorporates
a both XLD and LD elements, which produce a highly corrected image with reduced
chromatic aberrations and color fringing for improved clarity and color
accuracy.
Individual elements also
feature Tamron's BBAR coating, which suppresses flare and ghosting for greater
contrast when working in backlit and harsh lighting conditions.
Additionally, adding to the
versatility, an RXD stepping motor enables quick, near-silent autofocus
performance to suit stills and video, along with full-time manual focus
override and a minimum focusing distance of 7.5".
Suiting this lens's use in
inclement weather conditions, it also features a moisture-resistant
construction along with a fluorine-coated front element to protect against
fingerprints and smudging.
