Nikon D3300 vs D3200 vs D3100: 10 Memory
All three have a single SD/SDHC/SDXC memory card slot, but Nikon quotes UHS-1 card compatibility for the Nikon D3200 and D3300, which could prove an advantage for those shooting full HD movies - though for regular stills photography, UHS-1 compatibility is not really important.
Nikon D3300 vs D3200 vs D3100: 11 Wi-Fi
Nikon has only just starting building Wi-Fi capability into its cameras (the new Nikon D5300), but Wi-Fi capability has been available for a while in the form of the WU-1a adaptor. It's small, inexpensive (£50/$60) and plugs into the camera's accessory port.
It enables you to control the camera with your smartphone or tablet, transfer pictures and upload them to social networking and other sites from your smart device. It's a really effective system, and cheap too. The Nikon D3200 and D3300 are both WU-1a compatible, but the D3100 is not.
Nikon D3300 vs D3200 vs D3100: 12 Battery
When Nikon launched the D5300, it introduced a 'tuned' version of its EN-EL14 battery - the EN-EL14a. It's the same size and works in the same cameras (the D3000- and D5000-series models).
This new version offers a longer life between charges and is now used in the D3300 too, which can get 700 shots on a single charge, compared to the D3200's 540 shots.
The D3100 can get 550 shots before it needs a recharge. Battery technology is might not be very exciting, but in this instance it does represent a very useful step forward.
