    Great to see the first ring adapter. Based on my experience with this lens it is crucial to be able to visually check the distance setting. I have the feeling that the prototype hides the small window :-(

    There are many ways to overcome this. One is to use live view to adjust the focus for the first photo. I believe the focus point should stay even after the camera wakes up from sleep.
    The other is to make markings on the lens ring and the focus ring.

    What is your procedure for using the distance scale?

    The problem is, it is not mentioned on the NN e-store site yet. But send a mail for availability?

    Due to the USM drive markings don't help at all. The 5D (without II) does not support live view. Even if it would I would never rely on that. The final picture is out-of-focus if you turn the focus ring by about half a milimeter. That's why it is sooooo important to visually check the distance setting. Even to auto-focus an object in the far distance sets the wrong distance. I work with this lens for almost 5 weeks and see no way to overcome a hidden distance window.

    Just set it to a fixed, known value that I know it creates a sharp image from foreground to background (hyperfocal distance). With my lens its exactly between 1m and the infinity sign.

    Hi Michael,

    which zoom setting? 8mm?

    You are right, you only see the real result on PC. That's why we always recommend to do test shots, concerning focus, aperture, raising ISO. That way you know your lens a lot better without coming home with a ruined unrepeatable pano.

    Some of our NN friends like DennisS already machined a window into a lens ring to see the distance window. A small window won't cause problems to lens ring stability, depending on it's position related to the lens ring.

    Thx for sharing,

    Heinz

    Hi Heinz,

    exactly! I was doing all that in the very beginning when I got the lens: determine the NPP and the hyperfocal distance at 8 mm, 12 mm and 15 mm. In fact I was a bit disappointed that the lens needs a very, very exact setting of the hyperfocal distance. If I change the setting by half a millimeter (turn the focus ring left or right) the pano is ruined. That's why I do not use autofocus but set the found distance manually each time.

    Usually I shot at 12 mm.

    I'm wondering if others are having the same issue with this lens?

    I too have had this lens for weeks. I have found that using auto focus or live view to focus at the hyperfocal distance, that every thing from the near focus to far focus (infinity) is in sharp focus. This is done with my 5D MK II, I haven't yet tried it with my 5D.
