From their conclusion:
Sporting a more modern design that made its debut on the Opera 50mm f/1.4, this lens is well-suited to Canon and Nikon’s high-end full-frame DSLRs in both styling and size.
Less appealing is the slightly sluggish, audible AF system, the inability to fit a traditional filter system, and the lack of any weather-sealing, whilst the push/pull focal clutch mechanism is satisfyingly retro but less convenient than automatic manual focus over-ride.
Image quality is very good. Chromatic aberrations are well controlled and bokeh is surprisingly appealing when shooting at 28mm.
The only real optical issues are obvious vignetting and some barrel distortion at at the 16mm wide-angle focal length, a slight lack of centre sharpness when shooting wide-open at f/2.8 throughout the zoom range, and rather poor corner sharpness between f/2.8-5.6.Read the review…
