While an excellent ultra-wide zoom lens for film SLR cameras, the Canon EF 17-40mm f/4L USM Lens is especially well suited for use with EOS digital SLR cameras, which usually have an imaging sensor size smaller than the 35mm format. When used with such digital SLR cameras, the 17-40mm focal length range gives an angle of view approximately equivalent to that of a 27-64mm lens upon 35mm cameras, making it an ideal medium-aperture standard zoom lens.

The EF 17-40mm f/4L USM, like all of the Canon "L" lenses, delivers optical performance equal to similar fixed focal length lenses, with silent, high-speed focusing. Distortions and aberrations are remarkably small for a lens of such amazing capability. It combines 1 high-precision molded glass aspherical lens and 2 replica aspherical lenses to achieve the extended zoom range, while also correcting for common aberrations that arise during zooming. A Super UD (ultra-low dispersion) glass element minimizes the chromatic aberration of magnification which tends to occur with wide-angle lenses, to help eliminate color bleed along the edges of the subject and achieve high image contrast and resolution.

The 17-40's minimum focusing distance is just 11" (28cm) throughout its entire range of focal lengths, which makes it very useful for close-up work. All of the focusing and zooming action is done internally, with no changes of the size of the lens. It only uses lead-free optics to help the environment, and features a circular diaphragm for improved background blur. The housing is water and dust resistant to help ensure reliable performance for both professionals and enthusiasts. Like many "L" lenses, it uses 77mm filters, but also has a rear gelatin filter slot behind the lens mount.

This lens is a Canon 'EF' series lens, indicating it is for use with full-frame cameras. It works equally well with APS-C format DSLRs.

The Panasonic Lumix G Vario HD 14-140mm f/4.0-5.8 ASPH/MEGA O.I.S. Lens has an amazing focal range coupled with silent focus and electronic aperture adjustments, making this lens perfectly suited for all photo and video applications. Adopting the Micro Four Thirds System standard, the lens offers a wide and long zoom range that is equivalent to 28mm to 280mm on a full frame camera. This will suit a large variety of shooting situations, from scenery to portraits or telephoto shots, in a compact and lightweight body.

The lens uses four aspherical lenses and two ED lenses to achieve dramatic downsizing despite its powerful 10x optical zoom, while minimizing distortion and chromatic aberration. Panasonic's Mega O.I.S. (Optical Image Stabilizer) suppresses the blurring that is commonly caused by hand-shake, making it easy to shoot clear shots even at telephoto range or in dimly lit places without using a tripod.
