Next up is the Tamron SP AF 17-50mm F/2.8 XR Di II, which has a maximum aperture of f/2.8 and a minimum aperture of f/32.

Other key specs include its maximum magnification ratio of 1:4.5 and minimum focus distance of 0.27m over the entire zoom range.

The final launch is the Tamron AF 70-300MM F/4-5.6 Di LD Macro, with its maximum aperture of f/4-5.6 and minimum aperture of f/32.
