a new camera bag, again

At this point in time I have narrowed down of what needs to be inside my camera bag when I'm travelling:

- Nikon D600 + 24-85mm lens

- Nikkor 16mm fisheye (optional)

- Extra SD cards and battery

- iPad Mini

- Moleskine + pen

- travel guidebook

- phone juice pack

- water bottle

- earphone

- USB cable

- passport + tickets

All this time I've been carrying two bags, a National Geographic backpack (because I used to bring my Macbook on trips) and a sling bag to use when I'm already at my destination.

I was never into camera backpacks and have always gravitated towards the sling bag probably because it's faster to reach for the camera when I need to shoot some action. Or maybe because I used to play guitar a lot.So after doing plenty of research I've decided to buy myself (maybe after the New Year) a Think Tank Citywalker 10.

Hopefully I can stay with this one bag at least for, oh I don't know, a few good years?
