When changing your aperture to defocus the background, the light sources appear blurred. This bokeh' effect of the blurred background can be enhanced with circular aperture blades used in this lens. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. α lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result.
The distance encoder plays an integral part in ADI flash metering, which delivers high precision flash metering that is unaffected by the reflectance of subjects or backgrounds. The distance encoder is a lens component that directly detects the position of the focusing mechanism, and sends a signal to the CPU in order to measure distance to the subject. During flash photography, this data is very useful in calculating how much flash output is appropriate to the scene.
Hand-held low light shooting
Due to the large aperture, more light is allowed facilitating easier hand-held shooting, even in low light situations.
High contrast images
The SAL50F14 is designed to minimize flare and ghosting to help capture the strongest image possible with high contrast corner to corner.
- Extremely bright with superlative corner-to-corner resolution, superior clarity, and low flare
- Ideal for general purpose shooting, portraits and interiors in natural light
- Circular aperture for beautiful defocused effect
