Nikon SB -700 Speedlight £240/$330 What’s good: Wide range of modes, clear interface, good range of supplied accessories. What’s bad: No on-board switching between TTL and TTL-BL modes, no repeat mode. Our verdict: It’s not that powerful, but it works well and is great value. Nissin i60A £240/$340 What’s good: Impressive power output, compact build, graphical colour info display. What’s bad: Unlike its sibling, the Di700A, it doesn’t come with an Air 1 Commander unit. Our verdict: Packs serious power and features into a compact unit.
