Article Summary:

Wetpixel user Laz Ruda reports that Matthias Heinric has completed his eTTL2 converter and is in the final development stage of a firmware upgrade that will support 2nd curtain sync on the Rebel, D60, 10D and 20D at all shutterspeeds.  The digital adapter is a solid state circuit that goes between your camera’s hotshoe and the camera’s internal bulkhead wiring.  Currently, 2nd curtain sync with a Canon body can only be obtained when using a Canon speedlite, so this is a major feature addition for Canon shooters.
