The advantage for smaller flash is the larger guide number 20 at ISO 100, and that the head can be swiveled.
The delivery is next to the flash still a small leather bag for the safe transport, a description in several languages, and a holder for storage at home.
The flash intensity can be adjusted in seven steps on flash with the "EV / ADJUST" button (-1.0 -0.7 -0.3 0 +0.3 +0.7 +1.0), it is displayed on a 7 step EV (LED) display. Likewise, you will find a test release button, the lights at the same time (LED) if the flash is ready.
Plus, there's the obligatory "Power" button and a mechanical slide switch, the Slide locked the flash after the camera and ensures a secure grip.
In the Blitz 2 AA batteries or rechargeable batteries are used. I use "Eneloop" batteries that provide sufficient power. The flash is very fast and can have more times in quick succession (approximately 3 times) trigger before it is recharged for about 3 seconds. Who will flash once every 2-3 seconds, can trigger until the battery is empty. I am very pleased with this achievement, also the creative possibilities with the swivel head like me. For transport, the adapter connecting member can be folded inward, so that a small pack size is created. Since a times has thought along.
At the NX100 lightning does his job very well. I leave all the settings, in my opinion, underestimated automatic. Indoors and as a fill flash outdoors flash output is absolutely top. If you need more power, then you have the larger model, grab the SEF42A.
Very good I like plus the compact housing that fits well with the NX100, and this combination can not be to turn out clunky. So you also get the go a compact travel combination that yet can be easily transported.
For this flash I forgive like 5 points, and would buy it again at any time.
