The rumours were true - Nikon has announced the J3 mere months after the lid was lifted on the J2 model. So why such a quick turnarond?The J3 is smaller, lighter and, well, just all-round better than the J2. It's also got an updated menu system that's far easier to work through then ever before. But that might leave those who purchased a J2 a little miffed that they didn't wait an extra four months for the latest aluminium-bodied J3 model.READ: Nikon 1 J2 reviewIn use the J3 responds quickly; autofocus is super fast, supposedly even faster than its predecessors but it's hard to tell by eye because it's that quick.The updated menu system echoes that of the brand new Nikon 1 S1 model. There are six main tiles in the display that cover shooting modes, playback, special shooting modes, movie capture, image processing and set-up options.That means less faffing around to find the manual shooting options that you want, although the ongoing lack of a physical mode dial with standardised manual options is something we doubt the series will ever come to incorporate.The 14.2-megapixel mini compact system camera continues to boast about its special modes, including a high-speed continuous burst, smart photo selector and motion snapshot. There are also a batch of "arty" modes thrown in.A subtle upgrade, but the best Nikon 1 yet, and about time that the menu system was rearranged into something more user friendly.
