Photography Essentials
A sturdy bag to carry your camera, lenses and tripod
At least one camera, with full manual controls preferred
Wide angle lens: 10-16mm range for APSC bodies or 16-35mm range for full frame bodies
Standard range zoom: 24-105mm
Mid range zoom: 70-200mm
Camera strap

Optional
Specialty lens like an 85 or 90mm prime for portraits or a 35 or 55mm prime for street and general walk-around compositions.
Neutral Density Filters – at least 3200 and 10000 stop filters and lens mounting system for lenses you want to use them on.
Tripod, with a head and camera mounting plate of course
Memory cards and card reader
Extra batteries plus battery charger and cables
Laptop with your choice of photo editing software
Backup hard drive or something like Gnarbox. 500GB of space is plenty for photos on a 2-3 week trip. If you are doing a lot of video then you might want a 1TB hard drive.
Remote shutter release or intervalometer
Lens cleaning cloths
Small rocket blower or sensor dust cleaner
Waterproof baggies for rain or sand conditions
Flash – personally I don’t like it for travel photos but I also know a lot of pros who do travel with it.
