Among its many optical and mechanical innovations since the founding of the company in 1950, Tamron's development of mass-produced hybrid Aspherical elements in 1992 paved the way for today's compact high power All-In-One™ lenses. Tamron continues to lead in this category of lenses with the 16-300mm Di II VC PZD Macro - the world's widest All-In-One™ zoom lens at 18.8X range starting at an unprecedented 16mm true wideangle.
