I've been getting the itch lately to try out medium format. I've only shot 35mm before. I have a beautiful Rolleicord that takes 120 film but unfortunately the shutter blades are stuck and I don't have the money to fix it. I have a Kodak Duafflex II camera that takes 620 and I've read that you can respool 120 onto 620 rolls. Just wondering the difficulty level of this for someone who has never done it before. It seems fairly straightforward. Any advice would be greatly appreciated - thanks.
