I went into the store today to gawk and ogle the strange objects that I encounter. I saw 3 Tamron 75-100mm f/4 LifeTouch lenses. Clean and snappy apertures. Just wondering what size camera this might fit. The lenses are rather cheap and it might be fun to start a project to build a larger camera. Thanks! BTW, this is my first post in this forum. Shhhh don't tell my wife.
No these are larger than 645 or 67 lenses as I already own the 645 and regularly drool over the RB67 at National Camera Exchange. There was no bayonet on the mount either. This lens was a 5 pound monster with a 100mm+ front element. Maybe a photo of one will help or I could ask the cashier.
Maybe you could get in touch with LifeTouch Photography and ask them. However, the lenses on those cameras were monsters. LifeTouch is one of those companies that do school photography so the 75-100mm focal length makes sense for portraits on medium format film sizes. There is no mount because they were made specifically for the camera.
