The video show the lens mounted on sony a6600 camera, performing full zooming and wide angle range.
This is a Canon 6,7 - 121 mm f1.4 18x zoom Parfocal modified lens, for SONY E Mount APSC camera series.
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.
