Could some one tell me if there is a difference between an 8x10 carrier and the other smaller (4x5, 5x7) carriers? From the little research I've done the 8x10 carrier is suppose to be beefier. Is there a way to tell the 8x10 from the smaller carriers



Mike,

Sinar 8x10 made special rear carriers for 8x10 P and P2's and a special front carrier for the 8x10 P2. The rear carriers were wider to allow for centering of the wider carrier frames. The P2 front carrier has extra rise capabilty compared to the standard carrier.
