Their flag is extra wide

My crop sensor is also able to use Canon’s full frame lenses. I don’t think Sony or Nikon do that.

The sony E-mount works for both APS-C and Full-frame. You can even mount an APS-C lens onto a full-frame, but you are down to 10-12mpx on the a7, I think.

If you rock bigger hands, you may want to go for a slightly bigger body for comfort.

My a6100 grip is serviceable with my medium hands. Some fancier a6x00 cameras use the newer and bigger battery, which improves the grip size.
I also have an a5100 and the grip is way too small, but you can hold it like a waist-level TLR camera and it's okay. It's missing a viewfinder, which is absolutely terrible. It's my e-mount backup camera that came as a lens cap for a lens I bought.

For reference, I use my a6100 with a 70-350mm or with the 18-135mm. I sometimes slap on the sigma 30mm for low-light.
I'm happy with it, and I think even a a6000 would have been perfect for me (the a6100 is my starter camera from 3 years ago).

Whatever you choose, please make sure you figure out the ergonomics.
I have an a6100 and I find it big and heavy when I hike with it.
I recently started carrying it on a capture clip on my belt and it made it significantly better.
Don't forget to check the lenses too. Weight, price, size.

Cool!
The fit is very unforgiving. It might be hard to use with plastics that warp or with poorly adjusted printers... Or if the PCB is cut a bit larger.
I had trouble scaling the part and had to be... Creative. Thats why the thumb portion's shape is strange.
Glad to see it works for you!

Here's the first prototype I made in tinkercad.
I don't know how to do CAD modeling, but I'll try my best to make it fit well and I'll share the STLs.

Ah! I just recompiled, used your encoder config and the Henrik keymap, it is almost perfect.
Many thanks, the keyboard works really well now and I'll be modifying the keymap to my needs, it's already so close to what I need!
I'll move the NUM layer key to the left so I can enter numbers without lifting my mouse hand. :D

The part with the pickup trucks... idk.
I will not be able to design an intricate tilt mechanism in the short term, I have almost no CAD software knowledge... Thanks though.
I was planning on 'baking' the tilt into the case model or glue little feet.

Omg, thanks! I really liked the design/cost and it made me want to try the whole ergomech keyboard idea instead of just looking at pictures.
Your post explains so many things!
I'll jump on it as soon as I get back from work and I'll see if I can solve my issues.
Do you plan on updating the design? No push, just asking.

I actually bought myself an ergonomic keyboard months ago that does support tilting it in the other direction, with a curved wrist rest to help.
It works quite well, but I also like the concept of the one I built.
I's like to tilt it to make it more comfortable, if it turns out I like using it.
From what I understand, you can have all the keys you need on a keyboard like that, but it requires muscle memory of key combinations, and I do not know yet if that's for me. I'd have liked to start on a board with more keys, but it's expensive just to see if it suits me or not.
I can also see it being useful in VR while playing games like Elite Dangerous, to have one half per arm on a chair with a HOTAS setup.
It's definitely a niche thing.

edit: just read your other comments and I think you should chill a bit. I see these things as specialized and personalized computer input interfaces. People are different and input methods should be too. It might not fit your bill, but it might for some people here or maybe they like experimenting to find what works for them.
I don't want this to become a VI vs Emacs flame war analogy.

I also don't understand it at the moment, but I was curious so I built the cheapest good unit I could find to try it out.
Maybe I'll like it or maybe it'll go to eBay. We'll see.
What got me interested initially is the regonomic aspect of split keyboards since I spend most of my time at the computer and I'd like to avoid injury.

Oh thank you!
I might try this again on Linux and see how it goes.
It's good to know that the encoder can be fixed, I'll take a look how to do that.
Those are nice legs, might get some. I am also already in the process of designing a 3d-printed case that will also serve for tenting. We'll see how it goes lol.

Yeah, that's what I did with the qmk command line utility on windows...
I am new to qmk and custom keyboards so it's been confusing so far.
I'll try recompiling with another layout.
