The zoom ring is the wide one in front and the manual focus ring is the thin one just behind it. Yes, this lens extends forward when zooming.

The focus ring is the small one close to the mount. The large ring controls the Zoom and yes it does extend out.

I don't remember it saying zoom in the description, but in any case, it is not a zoom lens. There may have been a typo. I would disregard any mention of zoom for this lens. It does not zoom to a different focal length; it stays at 30mm.

No it is not a zoom lens. It's a fixed length prime lens. The 42.5mm micro four thirds lens is the equivalent of an 85mm lens in the 35mm system.

It is your basic camera lens, the one that comes with it, it zooms in and out, takes super clear pictures and allows you to get close to a subject and brings in further shots close. Not too too far like a telephoto lens however. Works well and takes a really good picture. It is the lens that just comes with the camera. hope that helps! You'll be happy with it!

This gold ring lens goes much wider, noticeably wider to the 24mm end. Must have a body which can set aperture since this lens has no aperture ring. No macro ability, but will shoot fairly close.

It is no a zoom lens. Might be an error on the listing. It is a 30mm prime lens with largest aperture of 1.4. FANTASTIC LENS

I am not sure wh8ich lens you are talking about. The zoom lenses do have aperture rings. However, the apertures are not marked on it. The 27 mm does not, but the aperture is controlled by the rear dial.

i have never used it on the zoom ring only the focus ring. Sorry for not being to answer that. Have you bought the product Jonathan? I have one for sale. Great shape. Rodney Howe 719-650-9909

I have had my lens for a year and love it. I do not experience any zoom creep by pointing then lens down, on its own. However if pointed down while traveling, it is easier to turn the zoom ring by bumping it against your body. However its very little.

It IS an autofocus lens. I suppose some vendors just don't include that in the description. Hope that answers your question.

No. This is not a zoom lens. This is a prime lens with only one focal lenght. No zoom!

The lenses are manual zoom, so you turn the ring on the lens itself. If you have a prime lens, like the 30mm, there is no zoom.

The front tube extends. It does not have internal zoom or focusing. However, the front tube does not rotate, making it possible to use polarizing and gradient filters.

it will not stay on focus ring- so I guess it for zoom only. Good question- if people can get it to stay on the focus ring they must have a wide ring. wont stay on any my canon lenses.

Everything is internal. the lens does not change length when zooming or focusing.

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.
