Irix 15mm f/2.4 Dragonfly Wide-Angle Lens for Sony E

This is the Irix 15mm f/2.4 in a native Sony E barrel rather than a DSLR mount with an adapter, which is why it weighs 662 g and measures 102 x 135 mm. Optically it is the same 15 elements in 11 groups giving 110 degrees diagonally on full frame, focusing to 0.25 m with a 140 degree throw and a focus lock for holding infinity.

The Dragonfly finish combines reinforced metal and composite elements with a scratch-resistant surface and engraved UV reactive markings, and the barrel is weather sealed. Aperture is reported to the camera, so semi-automatic modes and EXIF recording work. A 95 mm front thread takes screw-in filters. Front and rear caps, a lens hood and a soft case are supplied.
