Adjustable helicoid changes lens-to-sensor distance for macro magnification. Solid aluminium alloy construction with standard M42 mount gives a straightforward mechanical solution for close-up work.
Precise Close Focusing – With adjustable 17–31mm helicoid
Rotating the helicoid alters the barrel length between 17 and 31mm, moving the lens closer for short-focus distances and allowing fine, incremental focus changes.
Fine, repeatable adjustments help when composing tight close-ups and when performing focus stacking.
Turn Standard Lenses into Macro Tools – With added lens-to-sensor extension
Extra flange distance created by the helicoid enables lenses that normally cannot reach close focus to achieve higher magnification.
Use existing lenses for macro shots without purchasing a dedicated macro lens.
Durable Mounting and Adapter Compatibility – With aluminium alloy body and M42 mount
Good aluminium alloy construction pairs with a standard M42 thread, and compatibility with filter adapters broadens mounting options.
Secure connections and adapter friendliness make the helicoid practical for both field and studio macro setups.
