Hi Gerard, There may be some disadvantages in using an ST-E2 in place of the OCSC2, other than the increased battery requirements. When you run your 550EX as a wireless E-TTL slave, the unit emits a 1Hz red aiming blinking with the AF-assist beam. The only way I have found to turn this off is to use some masking tape :-( Have a look at the E-TTL recipes document: http://eosdoc.com/manuals.asp?q=ETTLRx The ST-E2 and Sigma EF 500 Super are about the same price. With the former, you get a replacement for OCSC2. With the latter, for the same price, you have the beginnings of a two-light Wireless E-TTL system. And you can continue to use the OCSC2 on a flash bracket, you can get very nice twin lighting, with automatic ratios, or even manual power control: http://eosdoc.com/manuals.asp?q=ETTLDx My regards to your family.
