A world of wonder awaits you Ultra-optimized optics create yet another incredible image
The new SP 15-30mm F/2.8 Di VC USD G2 (Model A041) is a high-speed F/2.8 ultra-wide-angle zoom lens that inherits the outstanding image quality established from its predecessor, Model A012. By utilizing specialty glass materials and aspherical lens elements in the new Model A041, Tamron’s engineers have further minimized the distortion and lateral chromatic aberration that can be an issue with wide-angle shooting. The lens also has triple lens coatings consisting of the newly developed AX (Anti- reflection eXpand) Coating, plus eBAND (Extended Bandwidth & Angular- Dependency) and BBAR (Broad-Band Anti-Reflection) Coatings, which all combine to provide sharp and clear images even in peripheral areas. The Model A041 lens features high precision AF technology and a powerful VC (Vibration Compensation) mechanism. A rear filter holder (for Canon EF- mount only) comes as a standard feature, making the use of filters much easier. As well as Moisture-Resistant Construction, wide-ranging features such as Fluorine Coating newly developed enhancing durability, make it possible to shoot under any type of shooting circumstances.
The newly developed AX Coating enables clear images
A new AX (Anti-reflection eXpand) Coating developed by Tamron using specialized deposition technology has enabled a uniform coating to be applied to the convex surface of large curvatures lenses, thereby resolving the major difficulty of applying a uniform coating edge to edge on a strong convex surface. This AX Coating, coupled with a nanotechnology-based eBAND Coating, and BBAR Coating, thereby enabling unsurpassed curtailment of ghosting and consequently enabling superlative, exceptionally clear image edge to edge.

Impressive high AF performance and image stabilization
In order to engage the full optical performance of the lens, it is essential to control the slightest blur and precise focusing. In this respect, the lens applies a Dual MPU (Micro-Processing Unit), which includes two dedicated MPUs, one for lens system control including AF, and the
Focal Length: 15mm Exposure: F/6.3 1sec ISO: 200
processing. other for vibration AF speed compensation and precision have been enhanced and image stabilization has been vastly improved, reaching 4.5 stops* according to CIPA standards. Even for handheld shooting, the blur that often arises in low-light conditions is effectively controlled. * CIPA Standard Compliant. For Canon: EOS-5D MKIII is used.For Nikon: D810 is used.
New Fluorine Coating for improved durability
The durability of the front element coating is greatly improved with the development of new Fluorine Coating. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture, and fingerprints. With this improved durability, your important lenses can now be safely protected on a long-term basis.
The rear filter holder enables greater creative flexibility
A filter holder that allows you to attach gelatin filters to the rear side of the lens is included as a standard feature (for Canon EF-mount only). You can now shoot with filters much more easily, traditionally rather difficult when shooting with ultra- wide-angle lenses with large front lens elements.
For greater protection when shooting outdoors, leak- resistant seals throughout the lens barrel help protect your equipment.
Optional compatibility with the Tamron’s TAP- in Console (Model TAP-01) lets you easily update firmware and customize the lens by making fine adjustments to AF focusing positions, and more.
