Used Nikon AS-17 Flash Coupler | U9

Summary

The Nikon AS-17 TTL Flash Unit Coupler is a dedicated accessory adapter engineered to extend full TTL flash automation to the Nikon F3 and F3HP series cameras, which do not incorporate a native ISO-standard hot shoe. The coupler interfaces directly with a broad range of Nikon TTL ISO hot-shoe Speedlights, restoring through-the-lens flash metering capability to the F3 system. An onboard ISO setting switch and ±0.33 EV flash compensation control provide manual override options for precise exposure management. Lightweight and straightforward to mount, the AS-17 is an essential interface accessory for any Nikon F3 system shooter relying on dedicated Speedlight flash.
