Description
Canon 17-55 mm EF-S F2.8 lens
Another great addition to the DLSR lens line-up, this Canon 17-55 lens covers the Super 35mm size (and APS-C) sensors of Red Epics, Blackmagic 4K cameras etc in 4K mode. You can use it on the Sony A7S in APS-C mode, but cameras that are only full-frame.
It has an image stabiliser which is great when hand-held and the very useful 17-55 range with a decent stop of F2.8 across the zoom range.
You can use this with an EF adapter on the Sony A7s, but be aware you can’t use this on a Metabones speed booster as the lens protrudes at the back and hits the glass of the speed booster. A regular EF adapter with no glass works fine.
The large circular aperture produces a shallow depth-of-field, creating background blur that draws attention to the photographic subject. The lens construction includes UD and aspherical elements, which deliver impressive image quality throughout the entire zoom range.
Image Stabilizer lens groups shift to compensate for camera movement so that the image appears steady on the image plane, ensuring clear, crisp images, even in dim light. With a Ring-type USM, inner focusing and new AF algorithms, this lens achieves autofocus quickly and quietly, and with full-time mechanical manual focusing, manually adjusting the focus is possible even in AF mode.
