Nice, intuitive, good value for money

I have used this with my monochrome Leica digital rangefinder. I use it in manual mode. I like it. The controls are straightforward and I use it in social, non-professional situations. (In the studio the monochrome rangefinder is wirelessly connect to Multiblitz and/or Broncolor strobes)

Quality Flas for simple portraits

Flash works as expected. Made well and clearly a Leica... just a bit expensive for the power level, but it’s a Leica so that’s expected.

Perfect light weight camera

Great travel camera! It has enough power to really take detailed shots. The MP is just enough. Fixed focal length got getting used to. It forces you, in a good way, to frame your shots more creatively and to get up close and personal to your subjects. Overall, impressive build and technology.

Very Compact

Helps if you are used to setting over/under manual settings as well as TTL... generally accurate.. very compact and handy... recycle time ok for general photos...recycle time varies considerably with distance to subject and ambient lighting.ISO... I have similar Nissan flash for Sony A7Rii... both work the same... Have not tried the built-in movie light...
