The 16-80mm f/3.5-4.5 Carl Zeiss Vario-Sonnar T* DT Standard Zoom Lens from Sony is a professional-grade 5x zoom lens specifically designed for the Sony DT Alpha and Minolta DSLR cameras. The optics of this lens have been optimized for smaller APS-C image sensors used within these cameras. With a crop factor of 1.5x, the equivalent 35mm focal length for this lens is 24-120mm. Carl Zeiss’ optical design and anti-flare T* (T-star) coatings used for this lens help to increase contrast and reduce lens flare.
- APS-C 35mm Equivalent: 24-120mm
- This 16-80mm lens has a 5x zoom factor, and is the 35mm equivalent of a 24-120mm lens on the cropped APS-C cameras it was designed for.
- Aperture Range: f/3.5-29
- With a maximum aperture of f/3.5-4.5 and minimum of f/22-29, this lens’ aperture changes depending on the level of zoom used to capture the image. If you start at 24mm on f/3.5 and zoom to 120mm, the maximum aperture will change to f/4.5.
- For DT Alpha & Minolta DSLRs
- Optimized for Sony Alpha APS-C sensor cameras, DT lenses employ an optical system that is specifically designed for digital SLR cameras which incorporate an APS-C size CCD image sensor.
- Carl Zeiss T* (T-Star) Coating
- This Carl Zeiss lens features T* (T-Star) coatings that reduce the lens flare, internal reflections and light scattering that can otherwise occur on the surface of the lens’ glass elements.
- 7x Circular Aperture Blades
- Circular aperture blades produce smooth, rounded bokeh background effects when capturing spot-light sources in your pictures. Because the aperture blades form a near circle at the wide openings used for low-light shots, spot-light sources have a pleasing circular defocused effect.
- Filter Diameter: 62mm
- The 62mm front filter thread does not rotate, allowing rotating polarizing filters to be used.
