Soke Engineering / Knokke film scanner

Where does the idea that this scanner uses a 1:1 lens come from?

Georg clearly said that they are using a small sensor - much smaller than FF. This is also evident from product images. A 1:1 lens would necessarily mean that there would need to be some stitching if you want to scan 135 film. Product images certainly don't support that idea as lens and sensor board seem definitely fixed and I really can't imagine anyone designing a scanner like this that moves the film up and down to scan all the different parts of the frame.

What am I missing?!

I agree that assumption doesn't add up; you're right.

Btw, lens in Minolta 5400 desktop scanner is a 8/4 design (magnification 1.8x), Nikon CS 5000 uses a 7/4 lens.

PS: I think it's also safe to assume that the choice has been for a CMOS image sensor with onboard ADC's since the electronics design and signal handling of doing that off-chip on a custom board would be akin to rocket science. No disrespect to the developers here, but that's a different league of EE.

Thanks @koraks - that helps a lot.

and thanks @gswdh and team. Never been interested in the whole DSLR scanning cottage industry but I'm incredibly interested in this project. It might be the replacement I need for when my Coolscan breaks.

Keep us posted!
