Frame up the perfect shot while composing on the go for less editing later. Get amazing wide-angle to mid-range telephoto shots with beautifully defined colors that make reliving the moment magical. Enjoy fast response and strong depth-of-field thanks to the wide f/2.8 aperture. ED Glass ensures brilliant shots with a wide array of color or try out Circular Aperture for pleasing defocused effects.
DT Lens Design A more compact llens designed specifically for use with APS-C size sensors.
ED (Extra-low Dispersion) Glass To reduce chromatic aberration at telephoto extension, correcting certain wavelengths of light for sharp, clear images with well defined colors.
Aspherical Lens Elements To correct visual aberrations at wide-angle setting, enabling a lightweight lens to capture more visually accurate wide-angle shots.
Wide f/2.8 aperture The SAL1650 features a large f/2.8 aperture for fast response and superb depth-of-field.
Circular Aperture Because aperture blades form a near circle at the wide openings used for low-light shots, spot-light sources have a pleasing circular defocused effect.
This is the magnifying factor of a lens. Macro lenses will often be described by their “magnification factor”. A lens with a 1:1 magnification factor produces a projected image on the sensor which is the same as the subject.
The individual pieces of glass that form the overall optical construction. Most lenses have between four and eleven elements to bend the light rays to ensure a perfectly formed image appears on the light sensitive surface, such as a film or CCD. The elements are arranged in groups and may be seen in specification sheets as, for example, 6 elements in 4 groups. That configuration may have two single elements and the other four grouped in pairs.
A lens with a 1:1 magnification factor produces a projected image on the sensor which is the same as the subject. A 1:1 magnification factor is usually considered the minimum for a lens to be described as a “macro” lens. Specialist macro lenses are often 1:3 or even 1:10 magnification factors, meaning that 1mm across the subject becomes 3mm or 10mm when projected onto the sensor, thus 3 or 10 times magnification.
