To commemorate 40 years of its ‘Superior Performance’ (SP) lenses, Tamron is launching a modern version of one of its classic designs, the 35mm f1.4 fast wide-angle prime. The new 35mm f1.4 (Model 045) incorporates many of the latest optical technologies and Tamron is describing it as its “ultimate lens”. The company also says that it represents “…the distillation of Tamron’s accumulated lens-making expertise and craftsmanship”.

Designed for full-35mm format D-SLRs, the new Tamron SP 35mm f1.4 Di USD prime’s optical construction comprises14 elements in ten groups which includes a total of seven special types – four made from optical glass with low-dispersion (LD) characteristics and three aspherical elements created via the glass moulding (GM) process. Consequently, Tamron says, exceptional uniformity of sharpness and brightness is maintained even when shooting wide-open at f1.4. The new lens also employs Tamron’s next-gen BBAR-G2 (‘Broad-Band Anti-Reflection Generation 2’) multi-coating for even more effective suppression of both flare and ghosting, ensuring enhanced contrast. The external construction is weather-sealed and a fluorine coating is applied to the exposed surface of the front element to help repel moisture and grease, while also enabling easier cleaning.

Autofocusing is via Tamron’s ‘Ultrasonic Silent Drive’ (USD) with the addition of an all-new ‘Dynamic Rolling-cam’ mechanism that’s designed to minimise the drive load on the focus lens component to give more stable and reliable AF operation. The lens also has a full-time manual override, and the minimum focusing distance is 30 centimetres, giving a maximum magnification ratio of 1:5. The minimum aperture is f16 and a nine-blade diaphragm gives smoother out-of-focus effects. The screwthread filter fitting is 72 millimetres. The lens is compatible with Tamron’s ‘TAP-In Console’ which enables firmware upgrades along with fine-tuning adjustments to the autofocusing.

The new SP 35mm f1.4 weighs in at 815 grams and will be available in the Nikon F mount from the end of June, and the Canon EF mount at the end of July. It’s supplied with a bayonet-fit lens hood and its own lens pouch.
