    Intrepid/Rodenstock question

    I bought a pretty minty Rodenstock 150 N 5.6 online
    I mounted it on a lens board and threw it in the intrepid mkiv

    When placing the front standard in the second hole from the front I canít focus to infinity all the way
    When placing it in the third hole i canít focus close but can easily focus to infinity

    Is this a problem with the lens or is this a normal thing that happens with certain lens (which is what intrepid told me)

    I guess I just assumed the lens would sit in one hole and be able to throw focus all the way from near to far?

    Should I try to return the lens or is having to switch holes normal
    And is there a downside to having to switch holes

    Thanks everyone

    So you just get use to which hole to mount it while setting up Iím assuming? Are there any 150s that rack front to back in a single mounting spot?

    Most likely no 150 can focus at all distances

    When shooting any lens I know we need more total bellows extension close up than at infinity

    Look up how Macro Photography works on any camera

    My biggest film camera has the capacity to focus from 14" to 75" with the same lense which is something like 5X magnification

    I'd did the same thing two days ago. With Velvia. Nice Shot.

    It's not the lens. Focused to infinity, you'll usually be at 150mm between the central point of the lens assembly and the film plane. The closer you get, the more distance between the film plane and the lens, until you reach 1:1, which is usually 2x the focal length (300mm in this case).

    So in order to use the lens at both ends, your front standard needs to be able to be at both 150mm from the film, and 300mm from the film. Sounds like the Intrepid doesn't have that spacing option.

    Frankly, I was astonished my Chamonix can (barely) pull it off. Then again, it's possible they specifically designed it that way. Regardless, that's probably the *only* focal length lens that will work at both infinity and close up in the same mounting location, so it's a good idea to consider "near" vs "far" when you're setting up the camera.
