Canon EF 24–105mm f/4.0L IS USM

The EF 24–105mm f/4.0L IS USM is an EF mount wide-to-telephoto zoom lens. It was introduced by Canon in 2005 to complement the well-regarded 17–40mm f/4L USM and 70–200mm f/4L USM. The lens is often compared to the other L series zoom of comparable range, the 24–70mm f/2.8L USM, losing one full stop but gaining image stabilization (IS) in return, stabilizing camera shake up to three stops. It also has rubber gaskets for moisture and dust protection, although weather sealing is only effective if the photographer uses a weather-resistant camera body. Some early production models of the lens had a flare problem (reportedly the first 10,000 batch)...

Canon EF 85mm f/1.2L II USM

  The Canon EF 85mm f/1.2L II USM Autofocus Lens is a fast lens that delivers superb optical performance. A maximum aperture of f/1.2 makes it the professional's choice for shooting without flash in low light conditions. The large aperture also provides fine control over depth of field for compelling portrait photography.    Retaining the impressive optical performance and large aperture of its predecessor, this medium telephoto lens has been improved with a Ring-type USM, high-speed CPU and optimized algorithms to achieve an autofocus speed approximately 1.8x faster than the original. The high-speed AF and circular aperture...

CANON 200-400mm f/4 IS 1.4x

For wildlife photographers and photojournalists, Canon has announced the new Canon EF 200-400mm f/4L IS USM Extender 1.4x lens (what a mouthful!), which we will henceforth refer to as the “Canon EF 200-400mm f/4L”. Weighing a hefty 3.6kg (8lb) in the red corner, this challenger packs 25 elements in 20 groups and measures 36.6cm (14.5”) in length. Like other new Canon super telephoto lenses, it is weather sealed and features ring-type ultrasonic motors with full-time manual focus override. Precisely on the February 7, 2011 development announcement of the Canon EF 200-400mm f/4 L IS USM Ext 1.4x Lens. I was personally excited – a Canon EF...

Canon 70-200mm 1:2.8 L IS II USM Review

The EF 70-200mm F2.8 L IS II USM was announced in January 2010 as a replacement for Canon's fast image-stabilized telephoto zoom, the EF 70-200mm F2.8 L IS USM, which dates from 2001. With the rapid increase in SLR sensor pixel counts placing lenses' optical qualities under ever finer scrutiny, the company clearly felt it was time for an update for this professional workhorse, and has revamped the design accordingly. In the process, it claims to have improved almost every aspect of the lens, including the optics, autofocus, image stabilization, and the mechanical design. The 70-200m F2.8 is one of Canon's L series professional quality lenses,...

Canon EF 50mm f1.8 II Review

Firstly, The Canon EF 50mm f1.8 II is a prime lens with a standard focal length of 50mm and a bright focal ratio of f1.8. Announced in 1991, it replaces an earlier 50mm f1.8 model, employing the same optics but housing them in a simpler all-plastic case to keep costs down; indeed it's the cheapest lens in the Canon EF catalogue, which in part has made it Canon's best-selling model. The 50mm focal length delivers standard coverage on a full-frame body, or 80mm equivalent on a Canon APS-C body, which acts like a short telephoto. The f1.8 focal ratio can deliver a very shallow depth-of-field, allowing you to place a sharp subject against a blurred...
