Thypoch announced Simera-C 21/28/35/50/75 in M mount (Cine version)

Basically, they’ve ported their cinema lenses to M mount. Interestingly, it appears they have focusing cams as well. It sounds like the intention is to use M mount as a universal adaptable mount. It’ll be interesting to see what these can do on my M10

Adding up the prices of the corresponding Summilux counterparts makes me dizzy...

With a red dot only the transport case would probably cost that much.

I was wrong as Al noted  - what I thought was a focus cam is simply the cutout on the mount lip. 
 

Also I’d read somewhere that Thypoch would announce a normal 21/1.4 M this week, hopefully that’s still the case.

I don't get really excited when lenses come with "screwdriver" and "shims."

I mostly gave up "playing boy mechanic" when I was - well - a boy. Now that I'm "grown up," I just create photographs.

Not a particular knock on Thypoch/Simera, though - they are not alone.

The "normal" Simeras (non-C) do not come with tools / shims. I have three samples and they are all well calibrated from factory and until now I saw no other user report about problems with their calibration.

The Simera-C cine line is not advertised as  RF-coupled, so there must be a different reason for shipping them with a screwdriver and shims.

On the other hand, I like the idea of providing an option for self calibration like we see with the lenses from TTArtisan.

Shimming cine lenses is standard practice. Not all manufacturers include shims, so it's a good thing that Thypoch does.

Unlike normal consumer oriented cameras, most cine cameras have adjustable sensors, so sometimes the backfocus of a lens needs to change to work correctly with various camera bodies and also other existing lenses. Remember, cine lenses often need to hit their distance marks perfectly to pull accurate focus and this is adjusted via shims to match the backfocus of each lens to the camera. The backfocus accuracy is much more important with wide lenses, as even a small error will create big problems. Ideally all lenses and cameras would be calibrated to the same standard, but this is rarely the case.

So these can only be used with live view to focus?

Not exactly- you can also zone focus using the lens focus scale, but no rangefinder.
