The Canon EF-S 18-135mm f/3.5-5.6 IS Lens is designed as a step up from the standard-at-review-time 18-55mm IS kit lens. The 18-135's most attractive features are a wide (7.5x) focal length range, a low price, a relatively light weight/small package, and a very nice IS (Image Stabilization) implementation. Let's review the physical lens first.
The EF-M 18-150mm does not suffer from severe vignetting. At 18mm, with lens at the maximum aperture of f/3.5, the corners show approximately 1.5 stops of vignetting. As the lens is stopped down to f/5.6, vignetting drops to about two-thirds of a stop. By f/8, there is essentially no vignetting.
