I'd love to have a 4x4 TLR. But I'm not a collector of equipment. I love shooting. I really love TLR style but I also realize that a true 6x6 is a HUGE camera (I own a yashicamat, good camera but not a carry everywhere camera..). So I'm thinking about baby-flex or baby-mat. What about film availability? Pros and cons..tips...film cutting...tricks..
