    This lens was delivered just a few hours ago and I couldn't wait to try it out.

    The first shot is shown as a reference, the coach shown here is an H0 model and the picture was taken with the Minolta MD Auto Bellows Macro 100/4.
    i-SVgB4vC-XL.

    The following pictures were made by mounting the 50mm lens on the Minolta Auto Bellows III, not applying any tilt nor shift.

    Intermediate magnification, uncropped image, taken at f/8
    i-9TgHdwR.

    100 % crop from the previous image
    i-DwF4CS3.

    At maximum magnification
    i-6p5NkGD.

    100 % crop from the previous image
    i-dTdmNpJ.
    I applied quite a bit of extra sharpening here and also eliminated the purple fringing that was visible around the white areas.

    I'm quite unexperienced in this real macro stuff, as opposed to close-up photography. The 50mm performs best at around f/5.6 to f/8, the image degrades quickly when stopping down further. The first picture was taken with studio flashes, calibrating the white balance with the X-rite ColorChecker Passport's grey card. The other pictures were made with a LED light source, WB adjusted with the same grey card, resulting in a wildly different color balance. Comparing it to the real world, the first one is OK, the rest is way off. And oooh, vibration... Sit still, hold your breath, wait at least 10 seconds before remotely triggering the shutter and thank heavens for the A7's electronic first curtain.

    I've Minolta Bellows IV and I like its potential but I found it very difficult to use with my rokkor non-macro lens; 58mm f1.4 and 135km f3.5. More usable with the Minolta Zoom 35-70mm f3.5 macro. Anyhow a great tool.

    In my experience the easiest lenses to use on a bellows are 100-135mm short-mount lenses. If you look around a bit, you can get an enlarging lens in that range for little money; add an MD-to-M39 adapter and you're set. See some examples here. I can imagine that a 135km is a little difficult to use :D.

    Nah. Just brace yourself against something big and solid. Like the Alps.
