The small size, versatile 35mm focal length, and outstanding overall performance of this Carl Zeiss Sonnar T* lens make it an ideal match for compact 35mm full frame format E-mount bodies. Although the optical design is state-of-the-art, this superb wide angle lens remains true to the original Sonnar concept with a bright F2.8 maximum aperture ("Sonne" means "sun" in German). Three double-sided aspherical elements minimize aberration so that stunning contrast and resolution are maintained right out to the image edges at all apertures. The renowned T* lens coating contributes to natural color reproduction as well.
