ANSWERS IN A FLASH!

Can you recommend an underwater Nikon?

Gecelle, via Facebook

Chris says… Pros would use a D-SLR in a special underwater housing, but a cheaper option is the new Nikon 1 AW1.

Are ‘Normal’ and ‘Active’ two levels of VR?

Quintin Gardner, via email

Chris says… Not quite. Normal is for hand-holding, Active is if you’re being shaken about.

Which is best: the Nikon 18-55mm VR or the 18-70mm?

Mandy Thawe, Lyme Regis

Chris says… The 18-70mm lacks VR but has a longer range and non-rotating front element.
