Very good on the NEX-7

I think it is a very good team - without any adapter.
The flash to the hot shoe fits, is not too heavy, easy to use, well made, gives good results and the price / performance ratio.

In this time of year I often photograph in my "home studio" (dining area) and regularly use a sturdy tripod.
The unfavorable light conditions require for well lit and detailed images often a flash.
I assume that with regard to the tolerable total weight of the camera, lens 50mm f1.8 OSS and lightning also exterior shots from the hand will turn out well.

This lightning I have now with this Metz found. The manufacturer Metz offers a warranty of 24 months.

Finally, I can recommend this flash without limitation.
