If we cannot have facts then we have to invent something

I just checked my actual shutter actuations on my 28 module and M module. I have had my GXR and A12 28mm kit for almost a year. The M mount since last February.

The 28 has 5957 actuations and the M mount 9756 actuations for a total of 15,713.

A tilt/shift lens should work better in theory on any EVIL-type camera, and probably better on the GXR-M than most. I have an EOS EF 24mm f3.5 t/s which I have used to record exterior shots of old buildings, must get about more and take some more. Where I live there are no old buildings (period). Not only was Australia fairly late settled but this particular region was later than most and a poor town made up of un-prepossesing weatherboard and fibro houses and nondescript public buildings. Since the prosperity of the 1960's the place has been re-vitalised and the population has grown (literally) five-fold. So no old venerable buildings here, although Australia has its share of colonial buildings elsewhere. Must get my travelling shoes on again.

Excuses, excuses .. but the point is that a tilt/shift on a Canon EOS body does not work as well as it might. The shift function, more at the extremes, messes up the inbuilt light metering and it takes a bit of fiddling to get the exposure right. This changes all the time on different shift settings and varies with the direction of light. It takes a few test shots to get it right. A live view body, or better, and EVIL-type camera should sort out a lot of this. Unfortunately Canon in their b-mindedness make their aperture adapter-unfriendly and there is no way to be able to shoot with this lens other than wide-open off an EOS body. But I do have a dumb EF->LM adapter somewhere must give the beast a fly on the GXR-M.

There are some "trick" EF aperture-functional adapters on their way (Metabones, Kipon) but they are only for NEX and M4/3. Might not be much point in holding one's breath for an LM version.

Wow!

That makes you professional-use level, hardly surprising that your body has a little wear.

For Tom. Happy you living in cozy small town without tall ugly structures sticking up their heads in the sky.
Still then, a tilt/shift has some interesting possibilities. One is well know scheimpflug principle widely used in landscape photography (extending DOF by tilt) and photographing planes that are not parallel to film /sensor plane ( walls, floors, close-ups). Shift was used, beside avoiding converging lines in architecture, for creating left shift-right shift stitched panoramas thus effectively expanding the area of your sensor ( in FF terms shift lenses covered up to 6x6cm). By the way, one could work on "Playmos GXR-M to be 12MP digital back" idea presented her on forum and use GXR-M on 4x5 field camera fitted with serious wide lens as a multishot device. Finally tilt was useful in photographing people from above head vantage point without need of tilting camera downwards and getting distortion.
I thought about M-PK or M-N adapter that had a tilt/shift mechanism. What a challenge for precision mechanic. The closest up to now is lensbaby system. Their Tilt Transformer worked with Nikon lenses but came only in MFT and Nex mounts and of unknown reason is taken out of production. Of course one can always lenswhack by hand . Easy now, it`s an expression for holding the lens with longer flange dist in front of shorter flange cam letting stray light influence the pict or shading it off at will, :mrgreen: . Hard to control.
