WORRIED that your camera flash can't keep up with the latest DSLR tools? In a world's first, says Nikon, the SB-900's brains - its firmware - can be updated.

This baby can fully illuminate an object 48m away compared to just 38m for its predecessor, the SB-800.

The circuitry boasts faster recycle times - just 4.5 seconds on lithium batteries versus 7.5 seconds on the SB-800.

The best part? It's cheaper than the SB-800, which is listed at $816.33.
