Following up on its popular S90 model, Canon has released the S95, offering about the same functionality, but with a slightly bigger 3.8x optical zoom and support for HD video. Like its predecessor, the S95 comes with one of the more impressive lens of any consumer point-and-shoot model, offering a maximum aperture of f2.0, which allows you not only to take photos in low-light conditions, but also gives you the ability to shoot photos with extremely narrow depth-of-field. The aperture of a lens controls how much light is let through. The lower the number, such as the S95's 2.0 setting, the more light is allowed in. The compromise is that the depth-of-field, or the part of the photo that is in focus in each shot, gets narrower as well. But this can be highly desirable in the sort of photos when you want the subject to appear in sharp focus, while the background is left blurred. The S95 also provides 10-megapixel image resolution, as well as HD video (1280x720 pixels) at 24 frames per second. It also has a control ring - first introduced with the S90 - that can be set to control particular shooting elements, such as the aperture and ISO, or used for manual focus. Better yet, the changes you make on the control ring, depending what you have set it to control - focus or exposure - are instantly shown on the display so you get a preview of the final result before you take your photo. The Canon S95 sells for HK$3,480 Pros: a great lens and control ring for exposure settings and manual focus Cons: there's no way to add additional lens enhancements, such as a fisheye lens
