Camera accessory that adapts legacy lenses for modern bodies, promising a mechanical bridge between mounts. Photographers who keep a favourite prime or telephoto will enjoy continued optical use without irreversible conversion. Does Hersmay Lens Mount Adapter deliver on infinity focus and metering compatibility?
⚡ At a Glance
- • Mount Compatibility: Adapts Nikon F mount lenses for use on Micro 4/3 camera bodies, manual focus only
- • Best for: Photographers who want to reuse Nikon F glass on Micro 4/3 bodies while keeping mechanical control
- • Not ideal for: Users who need autofocus or electronic aperture control with adapted lenses
Solid metal construction uses anodised aluminium for a secure connection. Photographic exposure metering functions on Micro 4/3 bodies and infinity focus is retained for lenses over 50mm.
Keep Legacy Lenses Working, thanks to Nikon F to Micro 4/3 mechanical coupling
Mechanical coupling mounts allow Nikon F lenses to fit Micro 4/3 bodies while preserving the lens flange focal distance. Manual aperture rings and focusing helicoids remain usable because no electronic communication is required.
Continue using favourite primes and teles without a permanent conversion, maintaining original optical character and manual control.
Maintain Infinity Focus, with focus calibration for longer focal lengths
Adapter tolerances are set so infinity focus is preserved for lenses with focal lengths over 50mm, relying on precise metal-to-metal flange spacing. Solid metal machining reduces risk of focus shift under normal use.
Accurate distant focus makes landscape and astrophotography practical with adapted lenses that are longer than 50mm.
Metering Works on Micro 4/3, thanks to preserved mechanical coupling
Photographic exposure meter compatibility is maintained by retaining mechanical linkages or aperture signals that the Micro 4/3 body can read. No electronic aperture control is involved, so cameras that read the lens mechanically will still meter.
Use in-camera metering rather than relying on external light meters, simplifying exposure for handheld shooting.
