Minolta Shift CA Rokkor 35mm f/2.8 - Minolta SR Mount

The Minolta Shift CA Rokkor 35mm f/2.8 is a specialist manual-focus lens designed for architectural photography. It provides a shift mechanism to correct perspective distortion, such as 'leaning' buildings. The 'CA' stands for Circular Aberration, referring to a unique feature that allows the user to adjust the lens's field curvature to better match the subject plane. It is a highly engineered piece of equipment for the Minolta SR mount, offering precise control over the image circle. Prospective buyers should ensure the shift mechanism moves smoothly and locks securely in place. SDS checks the internal mechanism for any looseness or play that could affect alignment. The glass is inspected for clarity, particularly the larger elements required for the shift image circle. We also verify that the variable field curvature ring functions correctly throughout its range, as this is a complex mechanical feature unique to this specific model.
