2. Pack Smart
When you decide which lenses you need for your trip, pack well to protect them. It helps to remember that lenses are made mostly of glass, even when built with highly durable exterior bodies. An easy packing hack to avoid damaging your lenses is putting them inside thick socks. This cushions your lens during travel, whether inside your luggage (carry-on only, never check your valuable camera gear) or camera bag.
Optional: further secure your lenses by putting them (sock-wrapped) into shoes/boots.
3. Make a Shot List
You do not have to be a professional photographer to make a shot list. As you research your destination, there are no doubt certain things that you want to see and experience there. As you plan your itinerary, you can make a note of what you want to capture in that location.
Take a note of your different points of interest and how you plan to shoot them. Sometimes this simple action can keep you from being overwhelmed when you get there. This will also help you determine what gear to pack (mentioned above).
