Together with the launch of the new touch-screen EOS 650D DSLR, Canon is launching two new EF lenses. (Pricing & Availability to be announced later).
The Canon EF-S18-135mm f/3.5-5.6 IS STM features reduced chromatic aberration with the inclusion of one UD lens element and one PMo aspherical lens element.
When used with the Movie Servo AF of the Canon EOS 650D, it also offers smooth, speedy and quiet focusing while recording.
This is achieved with the development of a new six-group zoom system, and the adoption of a stepping motor and focus mechanism.
Along with it, the Dynamic IS system features an expanded correction range, with image stabilization equivalent to 4 stops of light, which proves very useful when shooting subjects on the move.
The EF40mm f/2.8 STM comes in an ultra-compact and lightweight design, with a diameter of 68.2mm, a thickness of 22.8mm and weighing 130g, making it the slimmest and lightest EF lens produced.
A fast f/2.8 aperture, 7-blade circular aperture and aspherical lens elements enable the lens to achieve a high level of image quality from centre to corner.
