Build quality

The lens itself is made of a glossy black plastic shell over plastic internals and includes a detachable pancake-style lens hood. The lens itself is colloquially referred to as a pancake lens as it is currently the thinnest lens offered for Sony E-mount.

The lens can also be adapted with a 16mm ultra-wide angle or a 12mm fisheye converter, which are both sold separately from the lens itself. Neither allow for corrected Exif data to be recorded to the camera while the converter is attached.

Image quality

The image quality of the lens is significantly better than that of the 16mm pancake lens, suffering mild barrel distortion and moderate vignetting. Due to compromises made to keep its physical size to a minimum, the lens is one of Sony's softer lenses
