The Novoflex NEXA-K adapter ring allows the connection of Sony E-Mount cameras with devices equipped with the Novoflex A-Mount universal bayonet. This short adapter is specifically designed for use with bellows devices, including BALPRO 1 and T/S universal bellows via the APRO intermediate adapter, BAL-F universal bellows through the AFLEX intermediate adapter, as well as CASTBAL T/S universal bellows attachments via the AUNI intermediate adapter. It is a compact version of the standard NEXA adapter, optimized for bellows applications to maintain the minimum flange distance and ensure precise optical alignment. Made from high-quality materials, it provides a secure and durable connection, supporting reliable performance in photographic setups. The adapter features a black surface and measures approximately 45 mm in diameter and 10 mm in thickness, weighing around 25 g. This adapter is not intended for use with medium format adapters such as HARING, MAMRING, and PENTRING, or with historical Novoflex quick-change lenses. It is ideal for photographers looking to integrate Sony E-Mount cameras with Novoflex A-Mount accessories for macro, tilt-shift, and other specialized shooting techniques.
