My Rolleicord IV is loaded with Tri- X 320 220 film, the only B&W film available for 220, the five rolls box came with the Efke 25 6,5x9cm film sheets for the Rollei plates adapter a friend of mine bought for me in the States. I only took two photographs so far; the 220 film fitted in the 'cord IV perfectly, the guide paper start looked longer than the 120 guide paper start (up the film beginning)but I need to verify it after to develop the film. It seemed me film advanced too much before to engage the frame number one, but from one to two and two to three film advance was identical regarding 120 and then I think I have assured at least 12 frames. My idea is to open the camera back in the darkness after to take the frame 12 to put the film counter at 0 and I'll see the results..., I think it will work, the film sensor will "think" it has enough film in the upper spool to start the film counter again, I only have doubts about the final number of frames due to the film wound up before to engage the number one. I'll try the method in the Rolleiflex too.- Carlos Yahoo!
