Tamron AF 60mm f/2.0 SP DI II LD Si 1: 1 lente macro para cámaras SLR digital Sony (modelo G005S)

From the Manufacturer This exciting new lens is the first in its class to combine topnotch macro shooting performance down to 1:1 ( life-size on-sensor image ) with unequalled depth of field control and extended low-light shooting ability thanks to is ultra-wide F2 aperture. With a 35mm-equivalent focal length of 93mm, it’s a superb choice for portraits and its two LD glass elements and internal focusing (IF) endow it with exceptional imaging performance. Zoom in close at the 1:1 macro view The Tamron SP AF60mm F/2.0 Di II LD 1:1 Macro (model G005) is the industry’s first medium telephoto macro lens designed for APS-C size digital SLR cameras that features a fast maximum aperture of F/2.0 - one stop faster than the F/2.8 maximum aperture found on conventional macro lenses in the same class. The SP AF60mm F/2.0 covers an equivalent angle of view of 93mm when converted to the 35mm format. With its fast F/2.0 maximum aperture, the new macro delivers dramatically attractive blurred background effects. And the addition of Internal Focusing (IF) and Full Time Manual Focus Control Mechanism to its list of highlight features makes this lightweight and compact 1:1 macro lens incredibly easy to use. For Canon, Nikon and Sony APS-C size DSLRs SP AF60mm F/2 Di II Features Di II Portrait macro shot Lenses are designed for exclusive use on digital cameras with smaller-size imagers and inherit all of the benefits of our Di products. These lenses are not designed for conventional cameras and digital cameras with image sensors larger than 24mm x 16mm. Super Performance (SP) for Discriminating Shooters 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. Internal Focus (IF) Internal focusing (IF) provides numerous practical benefits to photographers including a non-rotating front filter ring that facilitates the positioning of polarizing and graduated filters, and more predictable handling because the lens length does not change during focusing. Even more important, Tamron's Internal Focusing (IF) system provides a much closer minimum focusing distance (MFD) throughout its entire focusing range. In addition, IF improves optical performance by minimizing illumination loss at the corners of the image field, and helps to suppress other aberrations that become more troublesome at different focusing positions. Low Dispersion (LD) Low dispersion (LD) glass elements in a lens help reduce chromatic aberration; the tendency of light of different colors to come to different points of focus at the image plane. Chromatic aberration reduces the sharpness of an image, but glass with an extremely lowdispersion index, has less of a tendency to separate (defract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic aberration at the center of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (towards the edges of the field) that often occurs at short focal lengths (the wide-angle end of the zoom range.)
