Create smooth, aesthetically pleasing out-of-focus backgrounds that make sharp-focus subjects stand out more vividly with the SAL-135F28 special purpose lens.
Smooth Transmission Focus
While subjects remain in sharp focus, out-of-focus backgrounds or foregrounds are blurred smoothly and evenly with gradation that thickens toward the edges of the frame for a pleasing aesthetic effect
Transmissive Brightness
After light passes through the apodization element, the lens aperture of f2.8 yields a T (transmissive brightness) equivalent of 4.5; a manual aperture ring can adjust T setting from 4.5 to 6.7.
Wide Focus Ring
The dedicated manual focusing system is controlled by a wide focus ring that’s comfortable to hold and gives you a solid, hands-on feel for pinpoint focusing of your subject.
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.
