The quality of the bokeh is exceptional, with super-smooth blur and particularly minimal longitudinal or ‘bokeh’ fringing. The aperture remains more well-rounded when stopping down a little, compared with Canon’s alternative EF f/1.2 and f/1.8 85mm lenses. Read our full Canon EF 85mm f/1.4L IS USM review for more details

Jan 18, 2016 • Review of Canon EF 24-70mm F4L IS USM 5 Just a quick review here after doing quite a bit of varied shooting with this lens using the Canon 6D only.
Has full-time manual focus. Canon RF 24-105mm f/4L IS USM. Sigma 24-70mm f/2.8 DG DN Art. With full-time manual focus, you can move the focus ring whilst it is in AF (autofocus) mode. This means that you can make manual adjustments once the AF has finished, without changing to manual mode.
The 70-200mm f/4L IS II gets Canon's excellent USM (Ultrasonic Motor) AF drive system, this one including a new high performance CPU along with newly developed firmware for higher speed and accuracy. This lens focuses very fast with even mid distance adjustments being made almost instantly.
