On September 2, 2015 Tamron announced a redefined SP (Superior Performance) lens series and the first two products in the line: the SP 35mm f/1.8 Di VC USD and the SP 45mm f/1.8 Di VC USD .

Having watched one of their main rivals, Sigma, garner all the recent plaudits with their popular range of Art lenses, Tamron have responded with the premium quality 35mm and 45mm f/1.8 SP prime lenses.
