new concepts - X/Y shift adapter for Sony a7/R

[Glenn NK]

So what EF/Nikon lenses (other than the tse/pc's) have image circles that are anywhere near large enough to be useful?

And a corollary to this might be:  Given a standard non-TS lens, what is the shift limited to with this gizmo?

There has to be a limit where shifting causes some serious vignetting.

I'm still confused as to where the image circle comes from , and if you are using canon lenses where the aperture control comes from?

Canon lens need to this.

1. must have electronic controlled adapter like metabones, I'm use from Chinesese adapter with velvet cloth.
2. aperture preset and shutter speed set to 2sec or longer.
3. shot and unmount lens during open shutter.
4. Your canon lens sticked preset aperture.
5. We can use preset aperture (super wide-angle lens's sweet spot if F8~f11).
6. When you return to adapter or canon body, Your lens automatically open.

It has No problem… I USED a lot of times about 5 years ago and Never problems...

Generally, Most of lenses are designed some enough to more 36x24mm image circle.
You can test your lens. turn off your room light and place lens and white paper. Then You can see your lens image circle.

modern lenses are very large room. new 40mm STM lens are almost cover 44mm x 33mm , very sharp even shifted edges.

please try it. old nikkor, leica R, con tax C/Y, olympus OMs are a huge image circles .

Even the cheapest 50mm F1.8 II (plastic mount) can cover full shift this adapter and Excellent sharpness.

I'm making 2nd version, Reverse type. It means Lens plane mount on tripod and Rear Sensor plane shift X/Y axis. So It has parallax free and can perfect stitching or shift.

I am very much looking forward to that. Even when I regularly shot with a view camera I prefered to keep the lens in a fixed position and shift the film holder's vertical and/or horizontal position.
