Canon EF 16-35mm f/4L IS DxOMarked

Canon EF 16-35mm f/4L IS

DxOMark tested Canon’s new ultra-wide EF 16-35mm f/4L IS USM zoom lens.

With a DxOMark score of 22 points the Canon EF16-35mm f/4L IS USM is generally a good performer. It has good peak sharpness, particularly in the center at 16mm from f/4 onwards, reasonable transmission of 4.5Tstops and low vignetting, though it’s still noticeable wide-open, particularly in the extreme corners at 16mm and more generally in the periphery at 35mm. Sharpness varies throughout the zoom range, as you might expect with a zoom but thanks to some curvature of field this lens has a rather complicated optical performance. At 28mm the lens has somewhat soft corners at full aperture, a marked increase in sharpness across the field at f/5.6 and then at f/8 a return to the lower edge performance seen at f/4. Geometry is good though (particularly at 20mm); there’s no difficult to correct moustache type distortion, only some barrel distortion at 16mm and slight pincushion from 24mm.

Canon Patent For Super Fast Auto-Focus Using 2 Motors (new STM technology)

Canon Patent

Egami (translated) spotted a patent filed by Canon for a new, faster auto-focus that appears to be the next step in STM lens technology. The AF in the patent is driven by 2 motors, the main STM and an auxiliary DCM motor. This should be useful especially for continuous shooting & focusing in the videographers domain.
