I've been thinking about how to make my motorised Rondinax base be converted so that I can use a Rondinax 60 (for 120 film) on it as well. The first prototype has just emerged from the kitchen table. I hope you will forgive me using non-analog photos of the device.
The motorised Rondinax 35 works perfectly on B&W, C-41 and E-6 films using standard times. I'll soon see if this holds true for 120 film. If the Lab-Box from Ars-Imago works out, it would be so easy for them to go on and provide a motorised base for it. I hope this inspires them!
