BEAUTIFUL BOKEH & RENDERING THAT CAN BE ENJOYED IN EVERY SCENE
HIGH BUILD QUALITY & OUTSTANDING OPERABILITY
Because this lens is intended for everyday use, particular attention has been given to building quality and operability. The lens barrel incorporating metal material as the main part achieves improved durability. Furthermore, thanks to the aperture ring with the right click feeling, comfortable operability during various shooting styles is ensured. The design gives consideration to MF operations, and a ring of appropriate torque provides good operability.
METAL BAYONET HOOD
The lens hood features aluminum, using the same material as the lens body which has realized the high quality and high rigidity. Furthermore, care for the click feeling at the time of when removing and attaching, the knurling process featured on the surface provides superior usability.
HIGH-SPEED & HIGHLY ACCURATE AF ENABLED BY THE STEPPING MOTOR
The lens is capable of smooth, quiet and high-speed AF made possible by a stepping motor, as well as supports Face/Eye Detection AF and video AF.
COMPATIBLE WITH LENS ABERRATION CORRECTION.
Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.
Rounded Diaphragm : The 7-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
Mount With Dust & Splash-Proof Structure ; The mount features a special sealing to make the lens an excellent choice in a wide variety of conditions.
Designed To Minimize Flare & Ghosting : From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA's Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high-contrast images even in backlit conditions.
High-Precision, Rugged Brass Bayonet Mount : The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
Fast AF With Full-Time Manual Focus : The full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.
