yeah it is about time they build a next gen flash,
one that use lithum ion battery, much like the one on their dslr.
where is the zoom function that cover 24-200mm?
what about build in one touch diffuser so that we do not have to put some tuppleware on top of it and look funny and unbalance.
what about using carbon fiber to make it strong and light, what about solving the problem that shooting portait, the flash make ugly shadow on left and right, much like sony solution, not the best, but better than nothing. flash head can bend from very far away from lens to close to lens, like mechanical snake.
and what about making one without battery, taking power from the dslr, in emergency or for people who want light flash.
what about flash with built in gps.
i honestly do not expect much from canon flash engineers, the history of canon flash is not one of innovation and excellent. i expect the third party to innovate and bring flash to the next level.
