Canon has created a lens offering outstanding quality -from image centre to image edge. The CN7x17 KAS S E1/P1 supports 4K resolution and incorporates an 11-blade diaphragm to deliver softer, more attractive out of focus areas. Thanks to an impressive 7x zoom, with focal length spanning 17mm to 120 mm, and maximum T-number of T2.95, the CN7x17 KAS S E1/P1 may be the only lens you need. A 3-group inner focus system developed for Canon lenses reduces focus breathing to an absolute minimum.
