I use a 124, the meter works great using an earing aid battery (1,4volts), it has a strange internal flare issue that can be easely solved using d-c-fix self adhesive velvet tipe material thatīs excellent to improve internal flare issues (also in other cameras... i used it in a deardorff, a burke and james and even in a recent shen hao and toyo and the flare was visibly lowered, i also use it in all LF lens boards!).
The lens, before the flare correction seemed more vulgar and i thought i had a bad example of the tessar copy.
After covering the film chamber walls i imediatly saw a huge improvment!
great camera although!
