Sony/Minolta A body + Praktica B lens
The difference is only 0.1mm...
lThe flange focal depth of the Sony/Minonta system is 44.5 m mm, while the PB has 44.4 mm. Ufortunately this means that the optics can't be properly calibrated (infinity zoom won't be available). We haven't found a direct adapter yet.The flange focal depth of the Praktica B bayonet lock system which was introduced in 1978 (bayonet or PB mount) is often specified 44mm incorrectly, while it's actually 44.4mm.
