I am abit confused here. Only the 4x5 condensors ? The same condensors do all the work, it just depends on what slot they are located in in the filter bin.Originally Posted by Bruce Appel
For example, if using a 150mm lens, you completely remove the tray condensor.
For using a 135mm lens, you put the tray condensor in the top slot
For using 105-90mm lens, you put the tray condensor in the middle slot
For using 80-50mm lens, you put the tray in the bottom slot
Hope this clears that up.
