    Hi All,

    I thought I'd share a surprising result I obtained recently. As you know, the Mamiya RB/RZ cameras use bellows focusing, so the shorter the focal length, the higher the magnification one can achieve.

    Some months back, I was walking on the beach, with just my RB67 and 50mm C lens. An opportunity presented itself in the form of a small beetle sitting on a twig, trying to dry itself. Now, any of you who have done 1:1 macro with the RB67 and the 140mm Macro lens know how cumbersome and massive the setup is, basically requiring a tripod, focusing rail and double cable release, together with both extension tubes (of course, quality is *seriously* good).

    So I though, why not give it a try anyway: I just focused to closest focusing distance, set the floating element to minimum distance (to correct as much as one can, although this of course goes way beyong what the lens was designed to do), put the camera down on the sand (love waist-level viewfinders...) and took the shoot (f/22 for [some] depth of field, 1s exposure, FP4+ film).

    The resolution and clarity on the subject is wonderful on a print, only the corners suffering from some serious field curvature.

    What a versatile camera system...

    I like your photo. I do have a RB67 and a 50 Sekor -C and this gives me ideas about how to use for macro, thanks!

    Nice. The lens is on my list for sure!

    The 55 on the C-series is good for stuff like your pic as well.

    It is indeed a versatile camera.

    I only wish that it was a 6x9 instead of a 6x7, because I often end up composing intending to crop and make the frame a longer rectangle. However, we can at least go to 6x8 with an RB. I am having a hard time deciding between an RB with 75mm shift lens and 6x8 back, or a Fuji 6x8.

    Surely you mean the 65mm C-series lens? I have and adore that lens, it's optically somewhat superior to the 50mm, an absolute perfect lens in my opinion. The 65mm is my general walk-around lens with this camera.

    Oh wait, now only do I realise you mean the 55mm lens for the C-Series of 6x6cm Cameras (C330, etc) and not the C-Series lenses for the RB cameras....

    Sorry for the confusion!
