Objektīvs Tamron 28-75mm F/2.8 Di III RDX for Sony

The Model A036 breaks all the rules regarding MOD. No longer must the MOD of a zoom lens be fixed throughout the focal range. The A036 reaches a MOD of 0.19m at the 28mm wide-angle end achieving a maximum magnification ratio of 1:2.9. A working distance of just 5.7cm from the front element allows you to shoot close-up with a sense of perspective unique to wide angles. At the 75mm telephoto end, the 0.39m MOD provides an image magnification of 1:4, allowing close-up shooting with a pleasantly blurred background similar to a macro lens.

The AF drive incorporates an RXD (Rapid eXtra-silent stepping Drive) stepping motor unit. RXD uses an actuator that is able to precisely control the rotational angle of the motor, allowing it to drive the focusing lens without passing through a reduction gear. The addition of a sensor that detects the position of the lens to a high degree of accuracy enables high-speed and precise AF, which allows you to maintain razor-sharp focus when shooting continually moving subjects or filming video. The lens is also remarkably quiet, eliminating concerns of drive sounds being picked up while shooting video.

A special glass with an extremely low colour dispersion index for the greatest level of sharpness and compensation of chromatic aberration.

The extension length of the lens does not change during focussing and the close focussing distance is significantly reduced across the entire focusing range.
