Greetings -
I've got a Toyo 45AII field camera. The focus locking mechanism does not engage as securely as it should. The problem is somewhat dependent on how much the be d is extended - it seems to hold better with more bellows racked out, as when us ing a longer lens or focusing closer in, than it does when I'm using a shorter l ens and I'm using little extension.
The mechanism is a little lever that, as far as I can tell, simply clamps down o n the rail to prevent the focus from changing. I am wondering if this is a use r-adjustable function - it seems that if I could just "tighten" the mechanism th at would do it. I can not see an obvious way to adjust/tighten the mechanism, s hort of doing major surgery on the camera.
Does anyone have any experience with this? I'd appreciate any suggestions. It 's not a disabling problem, just not convenient as I want to lock things down as completely as possible for shooting stability. I have not really had any probl ems with the focus shifting inadvertently, just want to be sure to avoid the pro blem.
It's a fairly new camera - I'm in the USA and it was purchased through Robert Wh ite (a very fine dealer!) so trying to do any warranty-related repair is rather cumbersome, considering shipping back to England, etc.
Thanks much...regards, Bill
