SP
Super Performance lenses are designed and manufactured to meet the demands of professional photographers for the best possible image quality.
XR
With Extra Refractive Index glass, light rays are refracted at steeper angles, allowing the physical size of the lens to be smaller, while still offering better performance and minimal optical distortion. XR allows smaller, lighter and shorter lenses to be made. However, there is no need to compromise on lens speed or image quality.

Tue
Digitally Integrated Desing lenses are designed for digital photography. These lenses feature advanced lens coatings and optical design that give a high quality image over the entire image area. Di lenses can also be used in full-frame, APS-C and 35mm film cameras.
LD
Low Dispersion glass elements have been developed to reduce chromatic distortions that make the image blurry. With LD, light rays of different hues are less dispersed on the image cell and more accurately focused at a single point than without LD glass elements.
ASL
Hybrid Aspherical Lenses provide the best possible image quality and compact size for long focal length zoom lenses. With ASL, Tamron has been able to virtually eliminate spherical and image distortion from large zoom lenses.
