Ever considered cutting away the front of the drum, ie doing away 
with the front 'slit'? Thereby giving the lens a full view during its 
entire rotation, and avoiding the sudden light/dark flare effects 
that will otherwise occur when the sun suddenly strikes the lens....

Note that all swing-lens cameras suffer from this, whether Horizont, 
Horizon 202 or Noblex 150.
But IMNSHO it is more inherent to the front slit than to the 
nature/operation of the camera.

Willem (wishing he could find a near total-loss 202 or Noblex to 
experiment with this) Jan
