Sirius can't get all that excited. By now he knows I'm going to pipe up and tell these people to get their mirror pads replaced. Otherwise a Hasselblad is not a Hasselblad. It's just some old used camera. See mine, over to the left? It's a 553 ELX. It doesn't have mirror pads on the bottom end. So 3 feet is accurate ± 1/8 inch or less on mine. Now THAT'S a Hasselblad. If you want to get anywhere near there with a CM, then get those pads replaced. Otherwise you're 6 inches off at 4 feet. That's pitiful. May as well have an Instamatic.
