Shimming if often used in PL lenses that have a scale for focusing. This scale is calibrated with a target like a Siemens Star or a Test Sheet.
Companies like P+S Technik do this with a rig where you mount the lenses and you can measure the focusing distance from the sensor to the target.
Once this scale is engraved cannot be changed as far as i now and that's why people shim the mounts.
Other cameras have "back focusing" that moves the sensor back and forth.
Photography lenses don't have this scales so they don't need shimming unless you want to change the range of focus to allow the lens focus more at macro or at infinity.
I think it's the correct solution to have the possibility to shim the mount, because otherwise you may need to move the sensor or try other more complicated ways to move and align the lens.

I created a concept for exploring enclosure options for shield connectors/interface/sensor placements:

Mobile internet allows cameras to become live broadcast studios anywhere there is coverage so while not a primary cinematography application definitely a TV camera application :)

"... the cool thing about the mushroom is that it can multiplex.

Could it be spam? As i don't see any purpose for 3G/4G in a camera.

Do you have foto-documentation of the build process online? And/or footage?
I would love to see your 3d prints and early assembly's :)

look at this A7sii Mod: http://www.centralds.net/cam/?p=7911

i like your approach a lot!
the super8 idea ist great, especially for artists and hobbyists who want to get in touch with AXIOM.
Also this has the opportunity to get people on board because it is a low threshold first contact to the project.

Some updates on this front:
Last ccc @vup @leftshift and me decided to build a cheap development version of the Beta.
We wanted to have a cheap camera to be able to develop soft- and hardware for the Beta without the need to invest a lot of money.
Research was done, the cheapest Zynq FPGA development board was found, the cheapest suitable CMOS with okayish documentation was picked and we designed a first Interface PCB to connect the sensor to the FPGA dev board. We build FPGA designs and wrote some software and in the end we had the first still images. The first prototype of the AXIOM micro was built.
However, the initial PCB was quite rough and had major problems (we were doing serious PCB design for the first time in our lives).
This led us to the creation of a second revision, which now is able to shoot moving images, has a proper lens mount and some case.

We found this.

It looks really cool!

@Gookfilm how do you want to connect the handle to the body electronically?

Awesome, that's perfect!

Scrolling back, I noticed you said ‘cool idea’ about the extra bottom hole a while back. It didn’t make it into the current revision though.

Snap, totally forgot about the Compact Shell! Which is kind of a cage, I guess. And cages are... You need to buy a cage or extra rails for more mounting points with every new camera you buy these days. It would be great if cameras had all the mounting points themselves. Saves both weight and money.

Hi Iwan.

And maybe add an extra 1/4” hole on the bottom end of the camera, right underneath the 1/4” hole on the right hand side while you’re at it. A rail there could allow my wooden side handle to be attached.

Thanks guys. For the camera to work without a cage, I really need at least two 1/4” holes on either side, vertically aligned. So the right hand side has got that covered, the left hand side doesn’t. One extra hole down below would allow a Nato rail to be attached and then we’d be home free.

More details: UP 2 Squared with Intel Pentium Quad Core up to 2.5Ghz N4200 with USB3 OTG, 1x SATA, 1x mPCI-e and 1x M.2 2230 E-key starting at around 320$ excl. taxes.
Dimensions: 85.6 x 90mm

another interesting candidate: http://www.up-board.org/ai-edge/up-core-plus/
no price or details on the expansion modules (SATA, PCIe) yet though

Added those to the doc. Any other questions let me know and I'll ask all together during next contact.

Is the foam ESD safe?
Is it conductive?

Looks good!

Dimensions: W11" x L10" x H7"

Yeah, well of course this is something that the industry wants you to do. Considering the number of Betas out there, maybe just write up a simple declaration for each country where the product has been tested with a super official looking checklist, get it signed by the "tester" and someone from the organization.
