I see that this lens has Manual focus capability. Does anyone know how the manual focus operates? Slip-ring or switch?

It has that standard AF/MF switch on the side. Set to MF and you adjust the focus with the ring. It's like the other lenses I've used from Canon and others. I'm not sure what slip-ring would be, unless you mean it focuses and then you change it. I haven't tried that.

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.

It is manual focus. You can beat the price. The quality is good and it is a super-big zoom lens.

Hello, the lens is manual, works manually only. Please put your camera into "no lens attached" mode and continue to shoot manually on in Aperture priority mode.Thank you.

It is a manual focus lens. I'm a Canon 60D user, but as far as I know it is consistent for all camera makers. I've read varying reviews on how to calibrate it, but the only thing that really does anything is the ƒ stop ring. The focus ring doesn't have the greatest effect, so I keep it at ∞. With all that said, it's a blast to use even with all manual features.

I use this lens with Canon 5D Mark IIIs to make films. It is a manual focus and manual aperture lens so the adjustments are made by rotating the rings on the lens. It has gears so it can be used with a mechanical follow focus. The aperture is declicked so smooth exposure adjustments can be made while filming.

Only in manual mode. I really haven't had a lot of use for, or success with this lens.

Mine does the same thing. Lens seems to work just fine. Probably has a friction clutch which permits the focus ring to turn past the stops

Manual focus only. Also it has a fixed so you'll be spending time getting your shutter speed and ISO set up for proper exposures. All in all a fun lens.

I figured it out. The lens can not be zoomed in to have full control over the manual focus. When zoomed out to a normal range, the manual focus will fully function, as well as macro, it seems.

Yes this lens is full auto focus, but there is no way to switch from auto to manual focus.

It has two controls for zoom, and you can use either. One is in front of the shutter release, and the other is on the lens. You change to manual focus in the menus. There are no control rings on the lens.

One can set it to auto or manual focus on the lens and it's easy to go from one to the other. Also there are settings for stabilization settings and 1.5 meters to infinity, or 3 meters to infinity, handy if there's a fence in the way. I love this lens.

Yes you can manually focus this lens. There are focus and zoom rings on the lens. You just need to set the camera to manual focus mode to do it.

Sorry, no. There is no mechanism for auto focus on this lens (difficult for this type of usage anyhow).

The focus ring controls a focus motor rather than using a direct mechanical system and has to be activated using the camera itself. I would think this lens cannot be used without being completely linked to the camera.
