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

[chiek]

It is prototype for mine.
It's not selling item but I have a lot of all stock parts so Someone wants, I may sell it.

Canon EOS EF lens mounts,(or Nikkor G adapter with aperture control? )
so virtually all major brand lens accepts because of shortest flange back DSLR.

X/Y axis GEARED shift mechanism. zero point locking system.
Genuine Schneider parts.
shift range : X/Y both +/- 5.5mm (total 11mm)
It has safety lens locking system unlike my earlier designing cameras.
similar to Hcam TS master (I like it !) but My design Can not tilt.

Very Hard work to Machining.

If I would making and selling.  How about your think?

but I am assuming (most) of canons lenses , and nikons, dont giev you a big enough image circle for 5mm shifts?

The Canon 24TSE does.

How about for Pentax 645 glass?

[ACH DIGITAL]

Amazing!!

The Canon 24TSE does. 

solution!

Excuse my ignorance, but if you have a tilt/shift lens, why would you need this adapter?

[Ellis Vener]

"Excuse my ignorance, but if you have a tilt/shift lens, why would you need this adapter?"

If the adapter can mount directly to a tripod, it will allow you to move the camera body instead of the lens. That will do two things: let you keep your exact point of view without altering foreground/background relations the way shifting the lens does, and also  eliminate parallax issues when stitching a panorama.

Chiek,

It looks great and I am definitely interested. I have four questions:

Does the adapter have a tripod mount?

Are there any issues with  the Sony A7r sensor work with the lens shifted off axis?

What would be the price?

Why the Schnieder logo on the front of the adapter?

Looking at the OP's images, the adapter moves the lens, not the camera body, and there is no  tripod mount.  Given this, it would seem redundant with a t/s lens.

"Looking at the OP's images, the adapter moves the lens, not the camera body, and there is no  tripod mount.  Given this, it would seem redundant with a t/s lens."

I should have looked closer. Disregard my comments, except regarding the utility of being able to shift body x/y position instead of lens position.

For what and I shoot, having a tripod mount on the adapter and being able to move the camera body instead of the lens would be worth it for me. From my view camera shooting days, I miss that feature.

Seems like there might be enough meat on the adapter to drill a tripod hole, if the material is strong enough to support both the weight of the camera and the Canon 24TS (IIRC, a pretty heavy lens).  I agree with you  about being able to shift  the body relative to the lens.  With that arrangement, it seems a moderately  easy process to adapt other wide-coverage lenses to the A7.  This would be an architecture photographer's dream.  I remember, not so fondly, the days of lugging my Linhof 4x5, 3 or 4 lenses, a case of holders plus a 120 back and a suitably heavy tripod.

"I remember, not so fondly, the days of lugging my Linhof 4x5, 3 or 4 lenses, a case of holders plus a 120 back and a suitably heavy tripod."

Same here Rip! But things got better when I went from a 4x5 Sinar C to an Arca-Swiss FC and then to a Canham DLC camera, and switched from double sided film holders to the Fuji Quickload system. And let's not forget about Polaroid and a 545i holder too. Plus the larger and heavier camera cases and Igloo coolers for film.

I still have and regularly use my very large and heavy Gitzo 410C tripod.

[Glenn NK]

To some extent this X/Y shift adapter is reinventing the wheel - and it doesn't permit tilt which I use more than shift.

Perhaps a simpler solution for the A7 bodies is to use the Canon/Sony adapter and a Canon TS lens.  The TS lenses have a larger image circle with much less chance of vignetting.

With the Acratech ballhead plus the quick release locking lever clamp, I can slide the whole camera in the clamp in the opposite direction but same amount as the shift.  The clamp is marked in mm.  http://www.acratech.net/categories/quick-release-clamps.html

I have done the same with the RRS camera bar and clamp and a shift lens.  They have a tutorial at http://www.reallyrightstuff.com/s.nl/it.I/id.38/.f

Chiek,

Prototype is no tripod mount but it is very easy to make tripod mount.

It was old schneider projector lens parts.

This canon mount hooked by a powerful spring.

Price... I want to many peoples use it. But machinist pay is us$1000 per day.
I have 8ea stock parts.

So I Offer to many photographer us$499 , not included shipping and paypal fee.
But quantity must be 8ea, if orders are not reached 8ea, then it's making is impossible.

It takes 2-3days to machining 8ea. So if it sold out (us$3990), machinist fee is about us$2000. And buying parts us$500-1000. My benifit's are a little.

If you're interest, please let me know.

If orders are over 8ea, I will consider to making.

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?

[ripgriffith]

The image circle comes from the design of the lens, and there doesn't seem to be any way to electronically control the aperture.  The device seems to be made just for manual aperture lenses in its present configuration.

[robdickinson]

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