Sony SAL135F28 - 135mm f/2.8 Telephoto Lens for Sony Alpha DSLR's Essentials Kit

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.
