and bright at its shortest focal length and loses very little brightness (less than one stop) when you move to the maximum focal length; that's better than most of its competitors. Naturally you could complain that the shortest focal length isn't a true wide...

Since these lenses have no microprocessor, you have to inform the camera of their focal length and their maximum aperture, but you'll get the benefit of functions close to those of modern lenses, and also see the focal length and aperture data in the EXIF information....

easily go beyond 10x, the R1 has a zoom ratio of less than 5x. On the other hand, the shortest focal length is equivalent to 24 mm (35 mm SLR equivalent), making it a true wide-angle, which is still rare outside the SLR world. The maximum focal length of 120...

love the angle of view magnifier because it allows lower focal length lenses to masquerade as higher powered telephoto lenses. But it is, after all, just a masquerade because a 50mm lens’s focal length is still 50mm even though an angle of view magnification...

win for the user.. Another important point that has not yet been discussed is the lens conversion factor, a basic concept in the digital SLR camera. The focal length of lenses (35mm, 50mm and others) is determined in relation of the format of the final image,...
