Other comparable lenses we’ve tested, however-the Nikon 35mm f/1.4G, Rokinon 35mm f/1.4, and Zeiss Distagon 35mm f/1.4-produced slightly better SQF numbers at the benchmark magnification of 11×14 inches. On our test bench, the 35mm produced Excellent-range SQF results, slightly better than the full-frame Canon 35mm f/2 IS and the Sigma 35mm f/1.4. The Tamron SP 45mm f/1.8 VC full-frame prime lens Tamron With a smooth and even turn and large, easy-to-read subject distance scales, manual focusing with both was a breeze.
Their Ultra Silent Drive (USD) autofocus motors delivered extremely quiet, quick, and accurate AF and also allow manual touch-ups in the AF mode. Both lenses boast extra resistance to moisture and dust, thanks to O-rings around the lensmounts. On our test camera, the Canon EOS-1D X, both of these Tamrons had a solid, well-balanced feel, and like all wide-angle f/1.8s they were on the heavy side-the 45mm especially so relative to typically featherweight 50mm f/1.8 glass. On most APS-C-sensor bodies, the 35mm and 45mm scale up to, approximately, a 53mm and 68mm (56mm and 72mm on Canon), respectively.
Tamron’s proprietary Floating system is built into both-the company claims this helps reduce the minimum focusing distance and increase sharpness across the entire focusing range. Inside, both of these Tamrons have one LD (Low Dispersion) and two molded-glass aspheric elements the 35mm adds an element of XLD (Extra Low Dispersion) glass. Tamron says it did this to accommodate the rising trend of super- high-resolution cameras (such as the Canon EOS 5Ds), which can record even miniscule evidence of camera shake. Unlike premium glass from rival companies, however, these Tamrons are the rare primes that throw in Vibration Compensation.
The new Tamrons sport a now-familiar satiny black finish and the other handsome cosmetics prevalent in this category. New to Tamron’s flagship SP line of Super Performance pro-oriented glass are a pair of surprisingly similar single-focal-length lenses: the 35mm and 45mm f/1.8 Di VC USD primes (each $599, street). These competitors include Sigma, Zeiss, and, to some extent, Rokinon, whose premier lenses generally provide large apertures, all-metal barrels, great builds, protection from moisture and dust, and sophisticated cosmetics that include sleek, matte black surfacing, crisp white barrel markings, finely ribbed focusing rings, and an overall luxurious feel in use. Tamron has moved away from its comfort zone in the zoom space and joined the growing group of third-party lens makers who are expanding into what might be called the new luxury prime market.
