Tamron Lenses for Canon and Nikon DSLRs

Tamron is a Japanese based lens maker founded in the 1950's, which made its early reputation on Adaptall lenses (lenses that could be adapted to different mounts) and then later the first superzoom lens for film SLRs (the 28-200mm f/3.8-5.6 in 1992). 

Tamron is not a huge company (only 6000 employees [2016]), and basically only makes optics (lenses for consumer cameras and commercial products). Sony is a major investor in Tamron.
