I've read this lens has no focus switch. Does this mean it's always in auto focus? Will I be able to have manual focus control for video?

I have the II. It has no switch. I've used it in auto focus only and I've never used it for video.

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

The lens has no focus switch. Most lenses don't. Camera settings are used to control auto vs manual focusing on both Panasonic and Olympus bodies. What you may have read is that the lens has no OIS switch. That's a switch to turn on or off the Optical Image Stabilization which is built into the lens. Some lenses have a switch to turn that off, but buttons or menus on camera bodies will also allow you to turn on or off this feature. Panasonic typically uses OIS in their lenses to help you to get a stable shot at slow shutter speeds. Olympus has Sensor Stabilization to do the same thing in the camera body, not the lens.

iam using this lens with a GX 1 camera. i just did a test and shot a video and focused manually after setting it to manual focus with a button on the camera.it worked.

This les does have a manual focus ring by which you can manually focus the lens. First turn off auto focus in the camera and then turn the front ring of the lens to focus it.
201803
I'm using this on a Olympus E-M10 which has it's own internal auto focus. When I turn that off manual focus works fine, I have no complaint about the ability to manual focus with this lens.

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.

Here is a REALLY obvious one. You can switch between manual and autofocus on this lense by pushing and pulling the autofocus ring in or out. It reads AF (autofocus) when pulled out, MF when pulled back in. This is distinct to Tokina, so not intuitive if you're used to other lenses. This lens autofocuses extremely well on my D7000 - it's my sharpest lens.

Short answer, yes. When in video mode auto focus, AF and AE are working. There is no manual focus. Even in camera mode there is no manual movement of the lens other than depressing the shutter button halfway. An additional note on video, when you zoom in there may be some changes in focus and the synchronization between focusing and zooming may cause momentary blurriness if the zoom is faster than the focus speed. You learn to avoid this. Also, keep in mind that your effective range of zoom in video is about half as much as camera because at some point you will be out of focus. There are always limits to what any lens system can. This last issue is not really important as you could not possibly hand hold the camera at max zoom in video to capture anything without excessive motion.

Re Yamada post: You can gain manual control over focus- one of the few things you can control in video mode. Just throw all hard switches to MF on your lens(es)... here's some test footage I shot with the hottest Latin Jazz Band in the world recently: http://www.youtube.com/watch?v=8uSHWi0pypYMy big gripe is that the camera "overheats"... and it's barely warm. I've been told to turn off steady shot to avoid this. Yes , a firmware update is desperately needed and would be awesome.All-in-all, you do get a lot of bang for your buck with the A55... images are stunning w/the right settings.//dc Re Yamada post: You can gain manual control over focus- one of the few things you can control in video mode.

Hello Brian, in the years I have used this lens all the time and I can report to you that I have never had any problems with this excellent lens. It is sharp and the contrast and color are beautiful. Focusing has always been crystal clear. Also focus speed would be a function of the camera body which has the drive engine for autofocusing. Hope this helps, Paul

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.

OK, let me preface my answer by noting that I rarely use my cameras for video. I have just tried a test video and it looks like it does autofocus with the 18-55 mm lens that comes with it. How it does with other EF lenses, I don't know, but since AF is built into the adapter, I would assume the same.

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

Are you sure? everything I have read so far states it doesn`t auto focus. Thats why I didn`t buy it yet. I can`t see buying one if I have to focus in shots anyways.

Don't quite understand the question but I have the Pentax version of this lens and it can operate in manual or auto focus. Just flip a switch.
386510
It depends on the kind of lense your using. The zoom ring has to be stationary so the band for the follow focus can stay in one place. What lense are you looking at using? Also autofocus doesnt really give you any control while shooting video. You would still want to use manual focus.

I use this lens on my 5D Mark II with great success. Set the camera to AV mode for automatic exposure, works just like normal AV mode except you use the dial on the lens to set the aperture rather than the dial on the camera. TV mode isn't available. Manual mode obviously can be used as well. There is no autofocus, but focus is very forgiving. I usually flip over to LiveView for a few seconds to focus the lens. Even on a 5DII the lens is amazingly sharp, beyond what I'd expect out of most L series lenses. Sweet spot is around F/5.6 or so, but it's sharp as tacks all the way to 2.8.

I used my old 30D lens with the adapter, a 75 to 200 and a 300 zoom, and the auto focus is really slow and noisy.. But I never use auto with video anyway.. Lock in the shot, and go. I use manual..

As stated by the other respondents, yes it has autofocus which can be switched off to manually focus. I've had no issues with the autofocus on my Canon 40d. I also own a sigma 1.4 teleconverter. With the teleconverter on the autofocus doesn't work and you have to focus manually. I've found that 500 is usually plenty of range so honestly I've only had the teleconverter on it once and then only to play around. I was also highly impressed with the OS (Optical Stabilization) on this lens. It is very heavy, but with the OS it is actually not nearly as hard to hand hold as I thought it would be. (But I always use a tripod if I can... no kidding it's very heavy!) Hope this helps! -ed As stated by the other respondents, yes it has autofocus which can be switched off to manually focus.

The only significant chance is that it has New lens (STM) that can focus quietly, improving video shooting experience. If you have other lenses I do not think it worth to change, unless you use it for specific video shooting.

Sorry, no. There is no mechanism for auto focus on this lens (difficult for this type of usage anyhow).
980020
No, not in auto-mode. But you can fine tune the focus when you switch to manual focus on the lens, and you leave the camera set for auto focus.This is different than other Pentax lenses that don't have the switch on the lens, this may be due to the fact that this lens was built by Tamron. I don't find this to be a big deal though, and enjoy the lens a lot!
