Excerpt: The flash that came with the Nex5n was definately sub par. This flash is considerably larger, and more powerful than the original. The bounce is a nice feature, but it is not adjustable i.e. in landscape mode, you can bounce off the ceiling, and in portrait mode, you can bounce off of a wall. The flash does a great job, but I have had issues getting it to mount properly and work. Several times I've had to remove it and re-mount it before the flash would fire.
