ALCS crystal sync 1KCP straight viewfinder Konvas

[Aapo Lettinen]

I figured out I could make adapter system to use my 4-speed Universal Crystal Motor with the old straight-viewfinder Konvas 1KCP cameras, the ones which had the hand crank and spring drive option with the large round spring motor cavity on the side of the camera. 

The adapter is a little more complex than on my other 4-speed mounting kits so the price is a little higher, for preorder 900usd with 4-speed motor and later on 980usd if there is still stock available. 

I need to replicate the big round mounting plate to hold the motor which is why it costs a bit more than other 4-speed mounting kits, much larger aluminium parts which are more expensive to cnc machine. 

The standard 4-speed crystal motor rund the Konvas 1m fine with the 200ft magazines so it would work fine with the older 1KPC which has those smaller magazines too.

If I get orders before January could start working on it in Spring2026 and hopefully shipping in April.
