Superb flash. Its assets: its price, compared to the same model in Canon. The power of lightning. Sync to 1 / 8000s. The integrated diffuser. Its autonomy. Weaknesses: little noise when you zoom (same on all models Yongnuo but not very annoying in the end) ... and that's it! In short, an unbeatable value for money. I use it on a Canon 70D.
