[Super35/APS-C] This lens had been purchased to be used with a Canon C300 Mk III. It is sharp, renders beautifully and is relatively lightweight for a zoom of this magnitude. The accompanying grip, however, represents a terrible mismatch for the C300 with its own grip attached, as they come so physically close as to make either one unusable. I have removed the lens grip and have placed it back into the box that it had arrived in and I suspect that it will never see the light of day. It really is a shame, since the lens grip allows for modulated zooms that excel when compared to the controls mounted on the lens itself. In summary, I would give 5 stars for the lens, and and 0 for the grip.

[Canon RF] This lens is a lot lighter than I thought it would be. What is not to like about a parfocal lens? The lens is expensive, but it is so much easier to use and allows the user to just concentrate on the shot or the story.

[112 mm] Saw this in Africa recently on a BBC truck on the same Canon CN20x50 Cine Lens. Mine at home did not have the handle that is made in Germany. So I called the company and they said I could get it at B&H. Wow not really a surprise since B&H has everything! Anyway this handle is a quality piece of gear for the lens. Screws are included along with simple instructions. Makes the lens much easier and, more importantly, safer to handle. Like I said, a must!

[Yes] I've had this lens for a while now and can say it's my favorite lens. Canon fixed the biggest issue I had which was a warm color shift on the 17-120. No color shifts on this lens! Flip on the built in extender and the lens can be ready for full frame. It's really the perfect lens for reality, sports, doc and most everything else.

[112 mm] As a documentary cinematographer, I'm always on the lookout for the ideal lens that can handle any situation. Traveling light is essential since we typically operate with a small crew. Previously, I used the Canon 15.5-47mm and 30-105mm lenses and often found myself stressed about selecting the most suitable lens for unpredictable documentary scenes. I was tempted to pickup a used 17-120 given the low price point, but when renting one, I found the 17mm just not wide enough for certain situations and often switched back to my 15.5-47mm. The new 15-120mm lens has been a revelation. The additional width at the wide end is transformative, yet it still offers significant telephoto capability. This lens handles everything from vérité-style shooting and B-roll to interviews, providing comprehensive coverage.

The build quality and weight of the lens are ideal for shoulder mounted shooting, and it performs well even when shooting from the hip. I use it with my Canon C300 Mark III, and it's safe to say I've found a perfectly balanced rig that's ergonomically satisfying and well-suited for my needs. I recommend having the lens calibrated at a Canon Cine Service Center. While it arrives in spec from B&H, the Canon techs can further calibrate its center sharpness. This lens is a game changer for documentary filmmaking.

[112 mm] Get over the price, it is worth it. Paired with my C300ii this lens wonderful. All functions work through the EF mount including autofocus (when needed). Powered via DTap to a Vmount. Has not left my C300ii body since mounted, except for a firmware update. Really has become a all in one lens for us. Great on the shoulder ENG. Great out sticks for interviews. Even does well on a dolly remote zooming.

[T2.95] perfect did not see anthing wrong on this zoom

[31.4 mm] Wonderful lens for the Blackmagic URSA Mini G2! Can control focus, iris and zoom using LANC thru the lens mount or ATEM software. Only bummer is the T4.4...would have been better with 2.8...but fantastic lens nonetheless.

[Yes] This lens had been purchased for a Canon C300 MK III, and it did not disappoint. It is sharp, contrasty and quick to focus in AF mode. My only complaint relates to the included zoom rocker grip. If this lens is to be used with the aforementioned cine camera, the grip will physically impede the use of the camera's own grip and it will have to be removed. I've replaced the zoom rocker grip with a 3rd party zoom control that completely solves the problem.

[Canon RF] We do a lot of Cinema and Broadcast style shooting and this lens does both. We were concerned initially with the 180 degree focus rotation, but we got used to it fast. The macro function is amazing! We are using it with the Sony F55. When we use the 2K center crop setting, the lens FOV essentially becomes a 35-240mm lens. It's light and don't notice a lot of breathing. I can't recommend this lens enough. With the F55 it powers the servo without any additional cables and passes meta data.
