Sony Sonnar T* E 24mm F1.8 ZA Lens This first-class 24mm (35mm full frame equivalent) prime lens features a large F1.8 maximum aperture & is capable of outstanding sharpness & contrast throughout the frame plus beautiful “bokeh” in out-of-focus areas. Maximum magnification is 0.25x for dramatic 1:4 close-up capability, & an internal drive motor offers smooth, quiet autofocus operation that moviemakers will appreciate. The ZEISS T* coating is an important contributing factor, effectively suppressing spurious reflections that can degrade overall image quality. Flare & ghosting are reduced for enhanced colour & contrast that give images a deep, three-dimensional feel. The black-finished aluminum alloy exterior of this lens affords an appearance that is eminently suitable for the distinguished ZEISS name, & of course it blends beautifully with the graceful design of E-mount bodies. The engraved focus ring offers sophisticated appearance as well as superior grip & operating feel. An F1.8 maximum aperture & 24mm focal length work with ZEISS optics to deliver outstanding images from well-lit landscapes to low-light indoor shots & even 1:4 close-ups. Legendary ZEISS quality manufactured & calibrated specifically for Sony imaging products. The T* coating contributes to exquisite rendering & contrast. MTF (Modulation Transfer Function) describes how well a lens can reproduce fine details, measured as the degree of contrast achieved between finely spaced lines.
