An ideal focal length for portraiture, the SP 85mm f/1.8 Di VC USD Lens
from Tamron is a short-telephoto prime designed for full frame DSLRs.
Incorporating one Low Dispersion element and one Extra Low Dispersion
element into the optical design, this lens is adept at reducing
chromatic aberrations and color fringing for a high degree of clarity
and color accuracy, as well as sharpness and resolution. BBAR and eBAND
coatings have also been applied to minimize flare and ghosting for
increased contrast when working in strong lighting conditions, and a
rounded nine-blade diaphragm contributes to a pleasing bokeh quality to
benefit shallow depth of field imagery. Classic in terms of focal length
yet optimized for the recent breed of high-resolution DSLRs, this
portrait-length prime melds a familiar perspective with contemporary
Complementing the optical assets, this lens is also characterized by
Vibration Compensation image stabilization, which minimizes the
appearance of camera shake by up to 3.5 stops for sharper handheld
shooting. Also aiding in creating sharp imagery, a robust ring-type USD
autofocus motor with an optimized USD actuator is used for noticeably
fast and accurate focusing performance. This focusing system also lends
itself to full-time manual focus control for fine-tuned precision. A
moisture-resistant physical construction enables its use in trying
environments and the front element has also received a fluorine coating
to guard against smudges and moisture from affecting image quality.
Additionally, this lens is compatible with the optional TAP-in Console
for fine-tuning focusing performance and updating the lens' firmware.
