About this deal
IS STM Lens, even though the optical formula is slightly different for these lenses (12/10 elements/groups vs.
With the 18-55mm IS, the distortion is fairly linear, and meets at the zero-distortion level at around 40mm. As usual, stopping down the lens reduces vignetting, though just over a stop of shading remains at 18mm f/8. With the camera powered off, this lens is far from being parfocal - the scene goes from in sharp focus to very strongly blurred and back into focus by changing focal length from 18mm to 55mm. Distortion is typical for a wide-angle zoom lens; lots of barrel distortion when zoomed to wide (18mm), approaches no distortion in the middle, and gets a bit of pincushion distortion at the telephoto end.
