A lens with high image quality and a compact, travel friendly size opens a world of shooting opportunities. With a zoom range from 70-300mm, you can change the framing immediately without having to change your position. Use it to capture candid portraits, pick out details in a landscape, or zoom in on timid wildlife.
High image quality is achieved by the use of two ultra-low dispersion lens elements and a floating lens group to produce high detail images with well-suppressed chromatic aberration throughout the zoom range. The 8-blade circular aperture ensures that out of focus areas exhibit very pleasing bokeh and circular out of focus highlights. This contributes to the high quality of the images produced by the lens.
The lens features a ring-type USM autofocus motor combined with a high-speed Central Processing Unit (CPU) and an optimised AF algorithm to make autofocusing both fast and silent. Because the lens has a ring-type USM, Full-time manual focus is possible allowing you to adjust the focus manually without first having to switch to manual focus.
A minimum focus distance of 1.2m throughout the zoom range allows you to get in close to subjects such as butterflies and flowers to really concentrate the viewer’s attention on the subject.
To improve the handling of the lens the zoom ring is located towards the front of the lens body, while the focus ring is located closer to the camera. The grip on each of the two rings is different so it is easy to tell both by position and feel, which ring adjusts focus and which adjusts zoom. When carrying the lens around or when storing it, the lock switch can be used to stop the lens inadvertently zooming due to gravity. This helps to keep the lens compact when not in use.
A ring-type USM autofocus motor, combined with a new high-speed CPU and an optimised AF algorithm, delivers fast and near-silent AF with precision. It also provides full-time manual focus so that you can adjust the focus with the focus ring, without first having to switch the lens to manual focus. This allows you to adjust the focus accurately to ensure it is exactly where you want it to be for the most creative control possible.
The Image Stabilizer in a Canon lens works by shifting a stabilizer group of elements to compensate for motion detected by a gyroscope in the lens. By incorporating the Image Stabilizer into the lens rather than into the camera body, it can be designed and perfected to work in harmony with that lens’ particular characteristics. This lens has an Image Stabilizer that gives up the equivalent of four stops of shutter speed so you can handhold and capture acceptably sharp images.
Fluorine lens element coating
Keeping the lens elements clean is highly important in achieving the highest image quality. To help with this, both the front and rear lens elements have been coated with Fluorine. Fluorine is a non-stick style coating that helps repel dust and water, and makes the elements easier to clean should any dirt find it’s way there from rain drops or fingerprints.
White lens body
Many Canon L-series lenses feature a white painted lens body. These lenses are painted white not to help them stand out at large photographic gatherings, but to help reflect heat when shooting in hot climates. If the lens body was to get too hot, the heat could cause the lens elements to expand, contract and shift around – this could affect the image quality. By having the lens painted white, heat is reflected helping to keep the lens body and lens elements at a more constant temperature.
Floating Mechanism and Rear Focus
The use of a floating lens element group helps correct aberrations throughout the whole zoom range. A floating lens element group is one that moves relative to the focal distance of the lens. Rear focusing helps speed up the AF by minimising the weight of lens elements that need to be moved. The elements used for focusing are distinct from the other lens elements and are placed at the rear of the lens. The combination of a floating mechanism and rear focus helps keep the lens compact while achieving very high image quality results.
The use of a rear focus mechanism also makes the lens suitable for use with filters such as circular polarisers because the front lens element does not rotate during focusing.
