The video show the lens mounted on sony a6600 camera, performing full zooming and wide angle range.

Enjoy incredible zoom-ins with constant focus, guaranteed by a Parfocal lens. This lens features a superwide optic from 6.7mm up to 121mm, with an aperture of f1.4. The lens is IF or internal focus, so like professional lenses, you won't have any moving parts visible. It is equipped with back focus to further correct the focal plane, work to eliminate aberration, and ensure exceptional Macro capabilities. Consider that you will need to perform a 2x Crop (or a Sony Crystal clear zoom to maintain 4K resolution) on an APS-C sensor, which effectively turns this lens into a 14mm - 242mm f.3 approximately, ensuring you a fast lens, cinematic bokeh, and above all unmatched creativity in the sector, at this price range. Experience the immense creative freedom provided by a unique and high-quality lens. The modification work includes the custom-built Sony E Mount bayonet already calibrated for Sony E cameras, so you won't have to do any extra work, just enjoy the lens right away.
