Tamron Announces New 10-24mm Lens
A High-Performance, Compact Ultra Wide-Angle Zoom
2. Features an Optical Design Optimized for Digital Camera Characteristics
• Special Optical Glass Materials for High Optical Performance
The new zoom lens uses a high-precision, large-aperture glass-molded aspherical lens element and three hybrid aspherical elements to minimize spherical aberration, coma, and distortion. In addition, a pair of LD (Low Dispersion) glass elements compensates for on-axis and lateral chromatic aberrations, delivering high optical quality.
• Optical System Designed to Optimize Angles of Incidence of Light Rays Reaching the Imager
The new ultra wide-angle zoom lens uses a new optical system designed to confine the changing angles of incidences of light rays reaching the imager within a certain scope over the entire image field, from the center to the periphery, addressing the effects of variances caused by zooming.
• Enhanced Peripheral Illumination
Peripheral light fall-off that becomes an image-degrading factor in wide-angle photography is minimized to ensure high optical quality from the center to the periphery.
• Outstanding Resolution
As an SP Di II class lens, it provides high optical quality in resolution, contrast, and flatness of image field.
• Internal Surface Coatings Reduce Ghosting and Flare
The lens uses newly developed multiple-layer coatings and internal surface coatings (i.e., multiple-layer coatings on cemented surfaces of plural lenses) to reduce the image degradation caused by the reflection of light rays entering from the lens front and affected by the imager.
3. Ultra-Compact, Lightweight Design
The new zoom lens covers a wider focal length range with a greater zoom ratio and offers a faster maximum aperture and enhanced optical quality than the existing SP AF11-18mm zoom lens (Model A13). Despite the higher specifications, the new zoom lens is lightweight and compact and accepts a 77mm filter, the same as the existing SP AF11-18mm F/4.5-5.6 Di II zoom lens (Model A13).
