Is this lens IF - does it change length as you zoom?

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

No Brian, there is no part that protrudes or extends, either with focusing or zooming. All movement is entirely internal, which I believe contributes to the weather sealing. It is a great lens and could not find a better alternative at this price point. I do not believe you will be disappointed in your choice.

No it dose not extend out. The internal lenses move, but they don't move out past the filter ring.

The zooming mechanism is internal, responding to a zoom ring located just inboard of the manual focusing ring. The lens remains the same length no matter the value of the zoom.

If you mean Zoom the lense YES. If you mean remove the lens and swap it out for anothe lens NO. I reaaly don't know by Move the lense.

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 lens does NOT physically extend longer than its original size. All the zoom functions occur within.

A zoom is lens that allows the focal length (magnification) to be changed continuously over a range. For example, a 25 - 100 mm zoom provides magnifications from 0.5X (wide-angle) to 2X (telephoto). A telephoto lens is one that provides magnification greater than 1X. For example, a 200 mm lens gives 4X magnification. It can be a fixed focal length or a zoom lens. A super-telephoto is one that provides high magnification. Generally super-telephoto focal lengths are in the range of 300mm (6X) to 1200mm (24X).

No, it doesn,t zoom. It is an excellent indoor and moderate range outdoor lens however. But you should buy lenses that suit the kind of photography you want to do. I for example, photograph alot, but I don't own a zoom lens at all.

The lens is a typical folding zoom lens that is at its shortest when zoomed all the way out, and extends two telescoping tubes as you zoom in (higher magnification). I.e., NOT an "internal zoom" -- doing that for something with this zoom range really isn't feasible.

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.

Yes, this is a fixed lens! So you cannot zoom in and out. But it is a beautiful one!! Best I have made portaits with!!!

This is a Micro Four Thirds camera and is like a DSLR in that it has interchangable lenses. All the "zoom" is in the lens. If you are looking at the standard power zoom then the zoom 14-42mm (35mm camera equivalent 28-84mm) and there is no digital zoom, again, all the "zoom" is in the lens. I have this lens and I also have the 45-150 (35 mm format equivalency of 90-300 mm) and that seems to cover my needs. You do need to stop and swap the lens if you want to use the longer lens.

Yes, the lens in this camera is incorporated in the body, you can´t change it. I had this one a few years ago, and it takes very nice pictures, but after two years the zoom's motor broke, and fix it cost almost the same as a new camera. A friend had the exactly same problem.

The lens increases in length about 4" when fully extended. It is not an internal zoom. There is no lock, and I have not noticed any "lens creep" when using it. The lens hood (which you need for glare and general protection of the lens surface) will add another 3" to the length. It weighs 3.31 lbs so add that to your camera weight. Hand-holding is not a problem, but a tripod is very useful.

No, unfortunately there is not. The ring on the lens adjusts the focal length only.

No. It's a static lens. Think of it like a large body point and shoot, with a really big zoom.

No, it's a fixed magnification. You can adjust the focus by getting closer or farther away from the object you're magnifying.
