Manual Iris too
I think I've loads of 1/3 format lens in s box somewhere,
I hoard stuff,
Lobbied a redcare stu, some webways & some emizons out the other week...
A body camera with a varifocal lens... how vintage
I'd assume the frame is the inside of the lens
Lens is in the wrong place or the wrong format
unscrew it, fit a space, change the lens ?
