My rather useless test of the Pentax DA L 18-55/3.5-5.6 lens (11 elements in 8 groups) on a full frame camera (Sony a7c). I was interested in determining the focal length at which vignetting becomes acceptable (this lens is designed for APS-C sensors with 1.5x crop factor).
Of course, the hood was removed. More precisely, the L version of the 18-55 lens doesn't come with a hood.
At 18mm:
At 24mm:
At 28mm:
At 35mm:
At 45mm:
At 55mm:
So I consider the Pentax 18-55 to be usable from 28mm on a full frame camera. By the way, 18mm on an APS-C camera is also equivalent to 28mm.
