Does the MTZ11 work with any M-mount lens?

Yes — Leica M, Voigtländer Cosina VM, Zeiss ZM, 7Artisans, TT Artisan. The lens doesn't need electronics; the adapter's 4.5 mm voice-coil tube shifts the lens bodily to drive AF.

Which Nikon Z bodies are supported?

Z6 II / Z7 II / Z8 / Z9 / Zf with the latest body firmware. v2.1 added Zf compatibility and tighter minimum-focus calibration for 35 mm and 50 mm Summicrons.

How does AF speed compare to native Z lenses?

Considerably slower — the motor moves the whole lens bodily, which is inherently unhurried. Best for static subjects, portraits, street, and product; not for action or wildlife.

Megadap MTZ11 — Leica M → Nikon Z adapter

Motorised mechanical-AF adapter: a 4.5 mm voice-coil tube physically extends the rear flange to drive autofocus on M-mount rangefinder glass — the Nikon-Z counterpart to Techart's LM-EA9 for Sony.

What it does

Works with any M-mount lens (Leica, Voigtländer Cosina, Zeiss ZM, 7Artisans, TT Artisan) — the lens itself doesn't need to know it's being autofocused.

USB-C firmware updatable. Eye-AF tracking works on Z6 II / Z7 II / Z8 / Z9 with the latest firmware. AF speed is unhurried by design — best for static or low-motion subjects.
