We apologize for having the detailed instructions available in German only.

To sum it up: We advise against using a YS50 TTL/S for digital cameras. Instead, it is recommended that you use a YS60 (no modification needed).

Please note that we do not offer support concerning the modification of the YS50. If you wish to modify your strobe anyway, you might want to take a look at www.mike-dive.de. However, as some YS50 are more than twenty years old and won't work with the DA2 or the TTL converter at all, we strongly encourage you to upgrade to the YS60 in order to use our products.
