Among the main improvements over the original RF-603 trigger set is the addition of a friction locking wheel and locking pin. The original model was plagued by not having one and that was probably the most complained about drawback of the budget triggers. In addition to the new locking wheel the new RF-603 II triggers offers improved “self checking” and mode switch.
The RF-603 II triggers will come with a Canon and Nikon specific version for flash wake-up. Otherwise, just as the original RF-603, the RF-603 II‘s are completely manual triggers. As for price, they remain one of the cheapest options available ($30-40 depending on the store) to anyone looking to get into the remote flash game on the cheap.
