I am fairly new to TLRs, but today I managed to get my hands on a Yashica MAT TLR and a Tokiwa FirstFlex TLR. I'm fairly familiar with shooting 120 (mostly Ilford b&w and Fuji color) with my Holga. The FirstFlex is extremely similar in that it has a film window, so I can wind until I see the frame numbers on the film backing, just like on a Holga. The issue with the Yashica MAT, is that there is a film counter (just like on a film SLR) however it's a locking mechanism. This is an issue since there is no way for me to see the frame number on the film backing, and a bigger issue in that the film counter starts after only a few winds. I know on my Holga it takes half a dozen winds to get past the backing paper and get to the first frame, so I don't know how to load the film properly in this TLR. Is anyone familiar with the Yashica MAT at all? Just for clarification this is not a MAT124 or a MAT124G, just a plain MAT. Am I supposed to unwind the film and remove the backing, and trim it to feed into the 120 roll? Any help or suggestions is greatly appreciated. Thanks!
