    Shifted up 10mm to fix key stoning.

    Miranda 24mm f/2.8 macro (OM mount). This is a Cosina made lens, sold under different brand names. Probably 1980s.

    Nice pictured .. looks like a good pairing .... Ilike it better with the second rendition .. I tend to think of these short macros and copy lenses rather than using them for general purpose ,,, interesting ..

    Both nice results David! The second turned out well with no visible keystoning. Now I am uncertain about the adapter. I had read somewhere before that some of the shift/tilt adaptors would not work on Olympus OMD bodies because the 'hump' on the top of the body interfered with the adapter. Do you have any thoughts on that from your use? The G9 has a hump but it may not extend forward as the ones on the OMD bodies do. I should get one if they would work on the bodies I have.

    Edit: I looked at the Kipon site David. The tilt shift adapter will not fit onto the OMD bodies but there is no disclaimer regarding the shift only adapter. I have original OM glass in 18 mm and 28 mm that may work for this application. Several other lenses but I don't know how useful anything longer than 28 mm would be. If I got a used PenF or a Pansonic body that would open up more choices.

    I have a shift only adaptor. It's quite small, looks like this:

    kipon.com/product/shift-c-y-fx/

    I got it a few years ago to use with my Gx7. Tried it on the G9 and the shift knob just clears the EVF hump. Tight, but usable. I used to have a G7 and the hump interfered.

    Just tried it on my EM10 Mki and it's fine on that. I'd say there was about 3mm gap between the knob and the hump when in the shift down postion, well clear at other positions. The knob is a little chunkier that has to be (for comfort I presume). It is secured by a grub screw so I think it could be replaced with a thinner or longer one that cleared the housing on some cameras that are currently a problem. Especially if you could source a thin lever-like knob like I've seen on some other adaptor designs (maybe other kipon designs). Like this one www.mu-43.com/threads/kipon-shift-adapter-first-and-last-experience.22516/ (although this one only sticks out when unshifted.

    It's certainly a cheaper option than some tilt shift adaptors if you can get hold of one.

    A 24mm lens gives a nice standard lens field of view, but a bit wider is often useful for shift for tall buildings. It's kind of hard to find cheap ultra wide vintage lenses for m4/3. I do have a Sigma 17-35mm EX lens in Nikon F mount with an aperture ring that would do the trick but my adaptor is OM mount. Have tried to find a way to convert it to F mount, but in the end gave up and went for a Tamron 17mm I found on ebay. Cheaper and easier to get hold of than a new shift adaptor. I did look at the Fotodiox but there were reviews on Amazon that said it has a dodgy mount locking pin that didn't work on some m4/3 cameras without drilling out the hole to a larger bore. That seemed all a bit too risky given the price of those things. Tamron should arrive in a couple of days. We'll see if it's any use.

    My little outing with it was just a quick test to remind myself how to work it. What I have found is that shift adaptors work well in conjunction with software. It's not always possible to chose the right amount of shift in the field. Maybe sometimes you shift too far or little. You can tweak in post and because the tweaks are just little refinements you don't lose many pixels.

    I've been using mine handheld, you don't need a tripod. Just use the viewfinder level to ensure you're pointing straight ahead, then shift to get the subject properly framed.

    I also find it's useful to shift down when you want foreground in your image without tilting the camera down. Here's one shot with my Sony and a Pentax 645 35mm lens:

    I think calling the Miranda/Vivitar/Cosina 24mm Macro, a macro is a bit misleading. It's really just a normal 24mm f/2.8 prime that can focus a bit closer than average. More marketing than real macro.

    Thanks David. I like that image taken with the Sony. A very nice result.
