Olympus 12-40mm f/2.8 - Does your lens go up and down when zoomed out?

    So I just purchased this lens new on Amazon and wasn't sure if this is how all the lens behaved or is it just mine? Need to know if I need to exchange or not.

    When you zoom all the way out to 12mm, the barrel doesn't sit all the way back, but extends a tad bit. When you start to zoom in to 16mm, the barrel is pulled all the way back where I expect 12mm to have been. As you zoom in more, towards 40mm, it extends as expected. Does that make sense or should I need to make a video? I also have a Canon 24-70mm L lens that I just simulated to see if it had the same behavior and it didn't. Can anybody with the same lens confirm this? Thanks in advance.

    Normal behaviour. Lens is shortest at about 14-16mm

    thanks 350duser. I also added a video just so anybody else with the same lens can confirm and see what I am talking about. Easier to watch a video than read the text. [video]https://dl.dropboxusercontent.com/u/54897262/2014-11-18%2022.06.50.mov[/video]

    That's how many DSLR lenses are. I can't confirm 100% but I'm 99% sure that it's normal.

    I thought so too, but when I pulled out my Canon 24-70mm f/2.8, it didn't exhibit this same behavior. Which is why I posted this thread and video. Just needed confirmation from other 12-40mm owners.

    That is normal. The shortest length of my copy is around 17-18mm according to gui.

    I kinda like it since 17mm gives my favourite field of view :)

    Same here, shortest length is about 14-16mm on mine also. I'm sure there are internal lens elements moving inside that require this length 'wobble' effect.

    I can confirm my Panasonic 12-35 f2.8 does not do this.

    Probably because it's not an Olympus 12-40/2.8 which has a different design.

    In addition to 12-40/2.8 I happen to own Nikon 24-70/2.8 as well. That lens is physically longest when the focal length is 24mm and shortest at 50mm. So the length of the zoom lens does not depend on the focal length.
