Flexible Aluminum Focus Assist Ring

Dimensions: 10 cm width × 8 cm depth. Crafted from solid aluminum alloy with precision-milled edges and uniform wall thickness. Designed exclusively for enhancing manual focus and zoom control on DSLR lenses with smooth external barrels. Flexible yet stable construction allows slight deformation during installation while retaining shape integrity during use. Inner surface is free of sharp edges or machining burrs. Colour: Matte black (anodised). Intended for hands-on creative control — not electronic integration, motor drive, or lens communication. Suitable for both static and moving shots where tactile responsiveness matters most.
