SP AF14mm F/2.8 Aspherical (IF) Rectilinear
Model 69E

The optical system of this lens comprises of 14 elements in 12 groups, including two large Hybrid Aspherical lens elements. These elements efficiently compensate for aberration to depict a genuine flat-field image from corner to corner. With a fast f/2.8 aperture and a sophisticated optical system, photographers can create dynamic photographs that take full advantage of the rectangular characteristics of the lens.

NOMENCLATURE
Super Performance series
Tamron SP (Super Performance) series is a line of ultra-high-performance lenses designed and manufactured to the exacting specifications demanded by professionals and others who require the highest possible image quality. In creating SP lenses Tamron’s optical designers put their foremost priority on achieving superior performance parameters – they are all designed to a higher standard with little regard for cost constraints. As a result, Tamron lenses bearing the SP designation feature impressive and innovative designs that have established an enviable reputation for excellence among those knowledgeable photographers that demand the very best.  Aspherical
Tamron uses several hybrid aspherical lens elements in its lenses bearing the Aspherical designation. These innovative optics achieve the ultimate in image quality while producing lenses that offer remarkable zoom ranges in extraordinarily compact packages. These cutting-edge advances have advanced the state of optical design by virtually eliminating spherical aberration and image distortion from Tamron's high-power-zoom series.
As one hybrid aspherical lens element can take the place of multiple elements without compromising performance, remarkably compact long-range lenses can now deliver a uniformly high level of image quality across all focal lengths and apertures.
Internal Focusing
Tamron's internal focusing (IF) mechanism provides numerous practical benefits to photographers including:
- a non-rotating front filter ring that facilitates the positioning of polarising and graduated filters
- more predictable handling because the lens length does not change during focusing
- a much closer minimum focusing distance (MFD) throughout the zoom range
- improved optical performance by minimising loss of illumination at the corners of the image field (vignetting)
- suppression of other aberrations that become more troublesome at different focusing positions.
Specifications, design, product name and standard accessories may differ
by country or area. While every effort has been made to ensure accuracy,
these matters are subject to change by the manufacturer without notice
or obligation.
