The Novoflex Stepping Ring 77/62 is a precision lens adapter accessory specifically designed for use with Fujifilm GFX retro adapter systems. This high-quality reduction ring converts filter thread sizes from 77 mm to 62 mm, enabling compatibility between different lens diameters and filter systems. Made from durable aluminum alloy with precise manufacturing tolerances, the stepping ring ensures optical alignment and prevents vignetting while providing secure connections between lens components. The black anodized surface offers corrosion resistance and a professional appearance. This adapter ring features standard metric threads with precise pitch specifications for smooth screwing and unscrewing without the risk of cross-threading. With a height of approximately 5 mm, an outer diameter of 77 mm, and an inner diameter of 62 mm, the compact design adds minimal space requirement to camera setups. The stepping ring weighs about 15 grams, providing lightweight portability with robust construction. Compatible with various lens systems that utilize 77 mm to 62 mm thread conversion, this accessory allows photographers to use smaller filters on larger lenses or adapt lens accessories between different diameter requirements. The precision construction ensures minimal light loss and maintains image quality through secure, flush mounting between optical components. As a successor to earlier stepping ring designs, this version integrates improved thread specifications and enhanced durability features. Suitable for professional photography applications where precise equipment compatibility is essential for optimal performance. The product is delivered without additional accessories or packaging, except for the protective storage pouch.
