The newly developed AX coating – for crystal-clear photos
The AX coating (Anti-Reflection eXpand), newly developed by Tamron, is based on groundbreaking technology that allows an even coating to be applied even to the convex surface of strongly curved lenses. This was very difficult in the past. In the SP 15-30mm F/2.8 G2, the AX coating is used in combination with other established coatings (the eBand Nano and BBAR coatings). This means reflections are minimised to an extent never before possible; the pictures are extraordinarily clear and bright, right to the edges.
Impressive AF performance and image stabilisation
To make use of the full potential of the SP 15-30mm F / 2.8 G2, max imum sharpness must be ensured at the moment the shutter is released. The dual MPU (Micro-Processing Uni t ), which contains two processors, one for autofocus and one for image stabilisation, makes sure this is the case. It both improves AF speed and precision and achieves image
stabilisation over 4.5 EV stops (according to the CIPA standard). Blur caused by camera shake while shooting free hand is effectively prevented.
* Measured according to CIPA standard. Measured using Canon EOS-5D MKIII and Nikon D810
Fluorine coating on front lens improved
The exterior of the front lens has a high-tech coating based on a newly developed fluorine compound with advanced water and oil repellent properties. This ensures that the lens is rugged and long-lived. The lens surface is easier to wipe and harder to damage.
Rear filter holder* for more flexibility with creative shots
The model variants with the Canon mount are supplied with a special filter holder as standard, which can be used to insert a gelatine filter or similar fil ter film in the rear of the lens. This means the separate filter holder for the strongly convex front lens is no longer available.
Weatherproof casing
The lens barrel is sealed against moisture. The design offers optimum protection in adverse weather conditions.
