Tamron has released the lens to coincide with the 40th anniversary of the SP series, calling it a "distillation of Tamron’s accumulated lens-making expertise and craftsmanship". It's been designed with 14 elements in 10 groups, and has been treated with the company's proprietary BBAR-G2 coating to keep contrast high and aberrations low.
The company claims that the lens maintains high resolution from the center of the frame to the edges, even at the widest aperture of f/1.4, while the diaphragm is said to keep bokeh round for two stops down from its maximum aperture.
Fast focusing
The lens also packs a USD (Ultrasonic Silent Drive) focusing motor for high-speed and precise focusing, while a Dynamic Rolling-cam mechanism, which has been specially developed for the lens, is credited as reducing the drive load placed on the focusing component, making for more stable AF performance.
Tamron has constructed the lens to be resistant to both dust and moisture, and this has been complemented by a fluorine coating on the front element to repel water and oil, and to make these easier to remove if they do come into contact with the lens.
