Andy, thanks for this info. I would have never noticed this as I sold all Nikon 21 years ago. But now that you pointed this, I remember that I always find the Nikon F-mount curiously small when comparing to Canon EF-mount. I (we) never noticed because the film plane is deeply recessed in the case of Nikon slr's film or digital. In the case of Sony E-mount the sensor rests very close to the camera throat.
For now, we know that the 17TSE won't be able to work with the A7r when shifted.

Well, FE-mount diameter is still larger than Nikon F-mount by 2mm and about same than OM-mount. Latter mounts have also much longer flange distance.

I think that retrofocal design of 24mm TS-E II would might help with this issue. Lens exit pupil is not very close to lens mount due to the shift mechanism.

Very interesting to see how it turns out and if a "plain" adapter without contacts would be better for this.

Just test it today with A7R and 17tse with metabones adapter mkIII.

rest assured,there is NO corner cut with 17tse fully shifted vertically or horizontally

Can't insert the SD card but i captured some image from the screen for you  :)

looks like a handy system, be interested to see how the lenses fare with smaller pixels than available canon offerings.
shame it doesn't tether.

EDIT: evidently it does but no idea what the software is like and if you can do a watched folder in C1

Both TS-E 17mm and 24mm L II have very high IQ so I don't think that will be something to worry about. a7r's 2 stops wider DR (vs. 5D mkIII) is more interesting for me.

The 24mm version is sharper though and one can use filters more easily with it. It is just not wide enough sometimes.

I share your screaming enthusiasm  :D  Best news of the year by far. For Canon TSE lovers at least.

Do you feel the pain Canon? I hope you do. Funny thing, Sony may well help Canon sell more lenses.

I would urge a cautious enthusiasm.

I believe that we are basing our hopes on only two very cursory tests performed by people with very limited access to the cameras. In fact, the only two reports we have so far appear to be contradictory on the point of vignetting with the 17TS-E, in't that correct?

Don't be a party pooper. :D
Seriously, you are correct. I usually tend to go by the last impression.

Ok Eduardo, ok...
Perhaps now there's a bit more reason for hope.

Have you seen this Dutch website's tests

Here's a relevant excerpt:

Quote
We wondered if there would shield the image created by the adapter or the bayonet and how the sensor would react to the image at an oblique would fall on the sensor. The results of the tests are convincing. The Alpha 7R has no problem with the Canon 24mm and 17mm TSE TSE. The image remains sharp right into the corners and vignetting is the same as the EOS 5D a little at full adjustment.

I remain cautiously (more) hopeful. ;-)

Hi,

The beam angle depends only on lens and not on the camera. The offset microlenses may a bit helpful light fallow in the corners. Raw conversion software may handle vignetting with a good lens profile and adequate EXIF data. These may be an area for hacking :-)

There is a risk that the bayonet opening may cut off part of the image, but this seems not to be the case.

Best regards
Erik

Edouardo,

So the a7r has been out for a while now and I am guessing that your questions regarding it's compatibility with Canon TS-E lenses have been answered.
If not, let me know. I'm currently testing the system.

Cheers,
Phil

Has anyone tested the Sigma 12-24 with the version III adapter and the a7r?  This is my workhorse lens and without it a a7r would be useless.

Yes, works fine in Manual Focus but no auto focus.

There is also this new option http://www.rjcamera.com/ocart/index.php?route=product/product&path=20_63&product_id=81

Note sure how is compares to metabones though.

I'm dying for someone to test this adapter with Canon TS glass. Fred Miranda posted he ordered one. I keep watching.

i use the metabones adapter together with the canon 17 and 24 tse lenses. it works perfect without any flaw. more problematic is the use of the nikon shift lenses. i dont bring them to work. i have a fotodiox and a novoflex adapter, both dont give energy to the lens and the ts-e lenses cant stop down without getting energy from the body, although they have focus rings. does anybody know an adapter which connects the nikons electronically? i would like to use this nikon 45tse cause its much better than the canon counterpart ...
