Sigma’s XQ range will have information added as it becomes available – we don’t have the original PR for this era. The YS – Yamaki System – lenses used interchangeable mounts in order to meet the growing SLR market’s wide variety of bodies. Unlike many adaptor systems, the YS allowed auto aperture and metering.
