This wired controller features a unique function: trigger, with the ability to block the button (pose b).
It is small (8 cm long) and made of a plastic - made in China - a little "light", but however carefully assembled.
In use the cable reveals a little short (one meter and dust), but I live with that.
Warning: it connects to the GPS terminal and the D90 is not compatible with all Nikon housings!
In short, the ideal accessory photographer "up" essential to take clear photos.
Fairly expensive store, for what remains a piece of plastoc but more affordable via the internet.
In the end, I am satisfied.
