Ultra-high zoom 4K lens

The largest zoom of any lens in its class with the ultra-high 45x ratio.

Canon CJ45 ex9.7B features 45x zoom ratio and wide angle focal length of 9.7mm to 437mm.

CJ45 would fit perfectly into EFP broadcast applications like wildlife/nature, sports, live events, documentaries, and helicopter/aerial.

Superior optics

Consistently supreme 4K performance is ensured by fluorite and UD glass which helps to minimise chromatic aberration and produces vibrant precise images.

Canon CJ45’s lenses are a step up from HJ40’s with quite a few enhancements. On top of supreme 4K optics, they are slightly wider and longer compared to HJ40. Zoom and Iris speeds have been increased as well. Those new ultra-high zoom lenses join the current 4K lineup of CJ12 and CJ20.

Bundle it up with Sony HDC-4300 or Grass Valley LDX 86N to capture most of the action with this ultra-high zoom 4K lens!
