Firmware update notice for Sigma's Nikon fit flashguns (NA i-TTL version)

To our valued customers,

Responding to enquiries received recently regarding the Nikon NA-iTTL version of the Sigma EF500 DG Super, Sigma EF500 DG ST and the EM140 DG when used with the Nikon D200 DSLR. We would direct you to the compatibility chart on our website which states that these flashguns do not support either the D2X, D2H or D200 i-TTL system.

To overcome this, we will be supplying a free-upgrade service to our customers. This free upgrade aims to respond to the demand of our customers by providing greater compatibility with Nikon fit flashguns (EF-500 DG SUPER NA-iTTL, EF-500 DG ST NA-iTTL, EM-140 DG NA-iTTL).

This firmware update service will allow the above mentioned flashguns to be compatible with the i-TTL systems of the D2Hs, D100, D1X, D1H, D1 and D200.

We will post further information regarding service procedure and time-scales in due course.
