Box Tengor
As promised I tried Rollei RPX 25 in the Box. The light at noon was really harsh. Unfortunately I still did not have my tripod with me so 3 out of 8 negatives became "motion" pictures :). I have checked the auxiliary lenses of my Box Tengor and they are not as nice as the front lens. I will have to find out how to remove them for a cleaning attempt. Actually the pictures did not show any problem... The Rollei RPX 25 became underexposed at f22 and just about right at f16 - despite the clear sky and direct sunlight. No problem: learning, learning, learning... I can perfectly understand why these boxes became so popular in their time (and actually scaled up film production).
