I read a review elsewhere that the manual focus ring will turn when the camera is auto-focusing in video mode since this is not the STM lenses, will I hear the noise caused by this in the video?

the autofocus is extremely loud and quite slow in video mode, and yes you will hear the sound of it in the video quite clearly. Also the lens will hunt for focus for several seconds. The only way I've ever been able to use this lens for video is to set it to manual focus. It takes some practice but you can get good at focusing it manually after awhile.

To the best of my knowledge all non-STM motors result in lens noise while recording. The other review sounds like they were confusing the full time manual (FTM) focus feature of most USM lenses as somehow creating more noise than non-FTM lenses, not true. STM lenses are specifically engineered to have a slower more controlled AF while recording video, thus producing less noise than all other Canon lenses.

mine is ok,but if you hear a noise when you have it on autofocus mode,that noise is normal(its like ka,ka,ka)

Yes, there's a manual exposure mode and the lens has a switch to turn auto-focus on or off.

Hi, the manual focus ring is mechanical, however, in has what we cann an internal focusing - only the middle groups of the optical system move to achieve focus so the overall length of the lens does not change. -Ely

Yes, you can focus manually. Manual focus is on the lens. Just circulate the lens, and you will manual focus the camera.

Yes. Zoom and Focus are manual with the inner ring for the later.It s a little bit to freaky not so gradual control.Its endless so no physical connection with lens I guess.

What Barry said. Ring spins infinitely however, so it's less than ideal for manual focus.

The whirring seems to be the focusing motor. Kind of bugs me to have that in the sound track of my videos. The image quality is better than the Sony SX41 (which I exchanged for this camera) but the sound on the Sony was crazy good with no sounds at all even if you listen at full volume! How about the IQ of the Canon and the sound of the Sony on one camera? :-) Gotta decide if I am going to keep this. If I don't, I'll be paying the restocking fee on both cameras.

Yes, this lens does have the option for auto focusing. But I clearly find that manual focusing is the better of the two choices. Unlike some lens, this option to change from manual to auto focusing is done by sliding the forward most ring, the one closest to the len's end back and forth. No switch. There is no automatic zoom option. You have to rotate the ring closest to the camera body to zoom in and out. I guess that is why I prefer the manual focusing. But either way, I am very happy with the photos I have taken with this lens. Hope this helps

Verify this but I believe it is correct. The auto focus depends on the lens and not the camera you are using so your question should be "Does Lens X auto focus during video".

The lens has no focus switch - your camera probably has one and it will control the lens. Manual focus during video recording depends on whether your camera allows this.

Yes, it's a clutch mechanism that allows slippage of the manual focus ring past the near and far focus stops. This is true for all my AF-S lenses.

I've been using the camera for about 3 months or so and was hesitant about using the auto focus/auto exposure because my last Canon video camera not only made noise, but it continuously unfocused and refocused throughout recording. I switched to all auto mode just to "see" how bad it was and haven't gone back since. I use Premiere Pro editing software and the audio is clean (we run a small soundboard and there's a tiny bit of hiss from there that the denoiser filter removes completely). But we hear no camera noises at all.

Usually yes. If you're in an auto mode there me be a delay for focus / light metering etc like most dslrs. However none of that in manual.

It automatic mode the camera focuses fine. I haven't tried it in other modes yet, but if you have an autofocus lens I imagine it will focus for you fine.

Yes, you always have to focus this lens manually. It works great for shooting video but can be really tough to focus manually for photos.

It is both manual and auto focus in both still image and video modes but in lowish light in video mode it hunts a lot, getting the focus wrong more often than not but thats a function of the camera. Not the lens. That said, it's an excellent lens but it should noted that it does not have image stabilization.
