Protective ring

The protective ring does not reduce the light beam but it acts as a protector so you can be more confident when shooting in tight spaces.

The new Retra Flash starts shipping on 21st July 2017!

Why is there a delay? When we realised that we can deliver a much better product (see improvements in specification from the announcement) we have decided to develop it and do all the necessary tests and accept that we will need to postpone the shipping. We hope that you will understand our decision.
We expect to ship all pre-orders until the middle of August.
