Everything From Broad Landscape Images, Portraits, Sports, Fast Action all the way to Wildlife Photos

Sony DT 18-200mm OSS Lens for NEX Cameras Sony DT 18-200mm f/3.5-6.3 Zoom Lens for NEX Camera. An 11 times 35mm equivalent 27-300mm zoom that can take care of everything from broad landscape images, portraits, sports, fast action all the way to wildlife photos using the telephoto range as high as 300mm. While the outcome will be accomplished, with Extra-low Dispersion (ED) glass which minimizes flare and vastly reduces chromatic aberration. There's quick internal focusing in 13 groups with 15 elements (which includes aspherical elements which correct visual aberrations all along the total zoom range), plus a circular aperture to create more pleasant out-of-focus bokeh areas. You should not use this lens on full-frame DSLR cameras.

Only Internal lens elements are what moves while focusing, as the overall length never changes -- resulting in a lens with quicker focusing and the balance doesn't change. Due to the aperture blades forming a nearly perfect circle when the wide openings are employed for poor-light images, spot-light sources create a pleasant circular defocused result. There ar three aspherical elements which correct visual aberrations much more effectively along the total zoom range and assist in reducing weight. A pair of ED Glass lenses reduce flare and vastly cut down on chromatic aberration, providing you with sharp, clear images even at the full telephoto end.

Advisory When Mounting DT Lenses On Full-Frame DSLR Cameras (35mm Equivalent)
Sony a lenses featuring the Digital Technology (DT) label are perfect for mounting on APS-C DSLR cameras they are not suggested for using on full frame DSLR cameras (like the Sony A900). While DT lenses may be mounted on full frame cameras, as they will only achieve a maximum of an 11MP size image (when mounted on the Sony A900), and aren't certified to provide precise Auto Exposure performance.

Superzoom
The term hyperzoom or superzoom is used to promote photographic zoom lenses with unconventionally large focal length factors, typically more than 4 and ranging up to 15, e.g., 35 mm to 350 mm. The largest ratio for digital SLR cameras is held by the Tamron 18270 mm, giving 15. Some Digital Cameras have even larger zoom ratios up to 35. For movie and television use, Panavision holds the record with their 300X HD Lens.

While superzoom lenses have improved greatly in recent years, they still have a number of drawbacks in comparison with shorter-range zooms and prime lenses. Most notable is the much increased likelihood of significant distortions of the image at both extreme ends of the range. Other potential problems include smaller maximum aperture and poorer autofocus performance

Following is a list of superzoom lenses, used for 135 format in SLRs or for APS format in DSLRs. The minimal factor used here is 5 or more. A 28200 mm has a 75 to 12.3 angle of view, a 28300 mm (or an 18200 mm for an APS DSLR) has an 11.1x 75 to 8.2
