Limited progress

A flash how to desires: small, compact, enough a lot of power to create indirectly or directly flashed a good illumination in normal indoors. However, the vaunted new features as opposed to its predecessor 270EX are limited with certain camera models available. I wanted him to use Canon 5D Mk II, but noted that it is not used as a slave flash without additional accessories here. Canon recommends the use of the Canon ST-E2 infrared flash trigger (for about 200.-) or the use of a flash with master function on the camera. You can use only unleashes the Lightning so if you can still buy a much more expensive in flash as master it.
The new button for remote tripping of the camera turned out to be a non-starter: While the camera triggers, but the flash is in the combination with the Canon 5D Mark II dark. Why then a remote shutter to the flash?
After all, can the 270 EXII when he connected with the camera attached to the hot shoe, control the camera menu. But that was also the cheaper, lighter and smaller predecessor.
Conclusion: Canon 5D MkII users should, if they think of unleashed flash shots, set another device. I have this returned again and use the predecessor on.
