making compact technical camera for A7/A7r

[ctz]

Looks great!!!
Thanks for sharing, Greg.

I've been using my A7r on my Cambo Ultima for almost 2 months now and its been great.   I am running the camera off the AC adapter, tethered to Sony RCC which then goes directly into C1 7.2.   I also have a 22 monitor on a rotatable VESA mount next to the camera stand for a larger live view.   

Sorry for the crappy iPhone pics

How did you attach it? Where did you get the adapter, is it on a lens plate? Can you use wide angle lenses?
Thanks!

Its attached directly to the Ultima 35 bag bellows.   I started by purchasing a Macro extension tube on EBAY for the E Mount - took it apart to get the actual metal mount and retaining ring off of it.   I unscrewed the nikon mount from bags, centered the new E mount on the bag hole, punched new holes for the new screw pattern and screwed it into the retaining ring which is on the inside.   Removed the rear mount and inserted one of my 35mm horizontal canon mounts which is screwed to a Hejner L bracket Base 4 and a Side 3 with the camera mounted on a Nikon TA-N100 spacer to raise the center of the sensor. 

Simple to rotate from H to V by just undoing the bellows at the lens standard and rotating the L bracket. 

Works great with my 28 digitar and 35 & 45 Biogons - no need for a recessed board and I can get the rear element all the way to the body.

Wow GregShapps, Great !
very similar to me. but I want to invisible A7 body, only visible to LCD screen and operating via mobile device (ipad, android phone).

Thanks for the info. Great idea, great use. I have 45 Cambo, still have to figure out how to put it on a lens board. I hope you Chiek will make an adapter soon.

update… almost done.
Canon Ef mounts. so It can accepts almost all lenses. (shortest flange back : 44mm)

Now I'm making wide bellows for this camera.

and Black matte Finish, Annodyzing(?)

This is 1st PROTOTYPE. It will change for better use.

[MrSmith]

great work. do the lens panels have to be custom made? be a great camera to use with the rodenstock apo-rodagons.

Yes, used existing bellows frame and MOD to canon EF mounts.

Looks great!   I like the idea of a Canon or Nikon lens mount on the front standard, I'll have to try that on the Ultima.

my design concepts,


Sony a7 has very short flange back so It can accepts Most lens. so I designed for shortest flange DSLR, Canon EOS.

I want breathe new life to old GX680 body within first mirrorless, Sony a7 body.

[uaiomex]

The new Hcam is also ready for EOS. Good thinking!
I'm a Canonite 
Seriously, it's the best choice by far. Not only shortest flange but also the biggest diameter mount in 35mm.

Thanks, Edurado.
Many people interested and asked functions. so I will generate for upgrade idea.

I think If this camera enable EOS AF & aperture control, like metabones3, It will be better.

I tried it and I think It can make it. but Very difficult work so Price will be very higher…



My idea added rear shift scale.

[chiek]

Today, 17TS lens tested.





Not Bad shifted Edge.
I will post tomorrow.

Arca-Swiss has just released the bellows for their DSLR2.  And we have redesigned the mounting to make it fast and easy to use.
The mount will allow the use of wide angle lenses down to at least 35mm and we are testing to see how short we can go with movement.
The rear of the lenses, especially on the Rodenstock's is so long that it contacts the body of Nikon's and Canon's below 70mm.
The Sony A7 series, being mirror-less, allow much shorter lenses to be used.
I will have pictures soon this week.

Additionally to make it easy to use, the bellows mount works as follows. Mount is pulled off from bellows.  That's right, pulled off.  It is a magnetic rear lens mount with a finger cutout to make it easy to rotate on the body.  Mount the bellows to the the front frame of your DSLR2 and reconnect the two rings via the installed magnets. As the two rings nest inside a perfect seal and light trap is created.  Turn on your body and you are ready to make images.  If you switch to vertical or vice-versa, you merely need to reorient the body and the bellows mount will rotate in place.  You now have an extremely precise camera capable of using wide angle lenses on your DSLR with ease.

All three mounts will be supplied in this form in the future.
Enjoy!

Very interesting ! Do you thing the HR-32mm will fit ?

[Rod.Klukas]

Still not sure.  I am trying to get the lens mount to sensor distance on the Sony.(depth of body...)
The 32mm has a 22.3mm distance at infinity behind the rear edge of the lens to the sensor for sharp focus.
The 23mm and 28mm Rodenstocks are both 16mm ...
