After launching the superb Tamron 18-200mm f/3.5-6.3 Di II VC, the Japanese giant in the field of lens industry Tamron broadens its SP series by bringing into play two prime lenses - Tamron SP 35mm f/1.8 Di VC USD and Tamron SP 45mm f/1.8 Di VC USD.
By introducing these two prime lenses, Tamron decided to 'shuffle its cards' and make its offer a little more diverse, bearing in mind that this manufacturer is mostly recognized as a company producing zoom lenses. According to the statements from the company, both lenses sport new design, different from what we have had a chance to see so far, both inside and out.
The Tamron SP 35mm f/1.8 Di VC USD and Tamron SP 45mm f/1.8 Di VC USD are aimed at both full-frame and APS-C DSLR bodies, and their fast aperture (f/1.8) enables the sensor to make use of every ray of light, thus delivering exceptional images, even in adverse conditions. Both of these fixed lenses are equipped with optical image stabilization (VC), and what is very significant for them is their short minimum focusing distances - 0.20m with the 35mm, and 0.29m in the case of the 45mm.
In addition to the optical stabilization, the new SP 35mm f/1.8 Di VC USD and SP 45mm f/1.8 Di VC USD share plenty of other characteristics. They feature 10 elements apiece (in 9 groups in the case of the former, and in 10 groups in the case of the latter), two of which are aspherical, one LD (Low Dispersion), while the 35mm also boasts one XLD (eXtra Low Dispersion) element. Both lenses are sealed, resistant to moisture and elements, whereas their front elements are coated with fluorine. As far as the coatings are concerned, there are also eBAND (Extended Bandwidth & Angular-Dependency) and BBAR (Broad-Band Anti-Reflection), which thoroughly suppress ghosting and flare, and thanks to the USD motor (Ultrasonic Silent Drive), focus is fast, quiet, and remarkably accurate. The diaphragms of both lenses are 9-blade, while the filter diameter is also the same on both models - 67mm. Aside from the focal length, the 35mm f/1.8 and 45mm f/1.8 virtually differ only in terms of dimensions, so the 45mm is slightly bigger and heavier than the 35mm - 540g in contrast to 480g.
The Tamron SP 35mm f/1.8 Di VC USD and Tamron SP 45mm f/1.8 Di VC USD will hit the shops in October, at the same price - $599. They will be available in Canon and Nikon mounts, while Sony Alpha mount will be released shortly (however, without the VC function).
