The Canon EF 8-15mm f/4L Fisheye USM lens is expected to be available in January of 2011 for an approximate retail price of $1,400.
Canon EF 70-300mm f/4-5.6L IS USM lens
Compact and lightweight, yet durable and professionally sharp, the EF 70-300mm f/4-5.6L IS USM lens is the ideal telephoto zoom lens for advanced amateurs looking for that extra reach to bring a subject in tight and close. Providing the power and durability to maximize every shooting opportunity, the Canon EF 70-300mm f/4-5.6L IS USM lens features two UD ultra-low dispersion glass elements for enhanced sharpness, L-series weather and dust sealing for shooting in harsh conditions, improved mechanical design, and streamlined ergonomics to help avoid inadvertent mode switch operation. The shapes of the lens elements and their coatings have been optimized to minimize ghosting and flare to produce high-contrast and high-resolution throughout the zoom range. A sophisticated floating system optical formula optimizes image quality at all distance settings and reduces minimum focusing distance by more than a foot. An updated optical image stabilization system compensates for camera shake up to an equivalent of four full shutter-speed steps, a full step improvement compared to earlier EF 70-300mm lenses. A new fluorine anti-smear coating is applied to the front and rear elements.
The Canon EF 70-300mm f/4-5.6L IS USM lens is expected to be available toward the end of October for an approximate retail price of $1,500.
Canon EF 300mm f/2.8L IS II USM lens
The Canon EF 300mm f/2.8L IS II USM is the 6th generation of a venerable family of Canon 300mm f/2.8 lenses that began in 1974, and have become famous for their exceptional sharpness, contrast and color fidelity. Ideal for a wide range of applications ranging from professional photojournalism and sports photography to nature and wildlife, Canon’s 300mm f/2.8 lenses have always led the industry with new technical advances in every generation. The EF 300mm f/2.8L IS II USM lens carries on this tradition with improved image quality, lighter weight, improved Image Stabilization and enhanced durability making it a great option for handheld work in the field. The optical formula of the new lens has been upgraded with the inclusion of two fluorite lens elements for improved image quality and reduced chromatic aberration. Helping to reduce arm fatigue, Canon has reduced the overall weight of the lens by 13 percent to 82.9 oz., making it the lightest weight lens in the Canon EF 300mm f/2.8 series. The Image Stabilizer provides an equivalent of approximately four full shutter speed steps of shake compensation and has been enhanced through the incorporation of a rolling-ball-friction system in place of sliding parts in the compensation optics barrel for a minimum-friction structure. The overall durability of the lens has also been enhanced through increased usage of magnesium alloy and titanium for lens barrel components, together with weather sealing for all exterior joints and switches and a new fluorine anti-smear coating applied to the front and rear elements.
The Canon EF 300mm f/2.8L IS USM lens is expected to be available in December for an approximate retail price of $7,000.
