Travel Tripod
A Guide to Tripods for Travel Photography
A tripod is an essential part of a photographer’s equipment list. Its primary function is to provide, solid, stable support to the camera, allowing the photographer to shoot with a much slower shutter speed than would normally be possible if the camera was handheld.The reasons you might need to use a slow shutter speed include:
- Low Light – When the light is insufficient to provide a suitably high enough shutter speed.
- Depth of Field - When a photographer is using a deep depth of field i.e. a small aperture the shutter speed will subsequently be much lower.
- Macro – When shooting subjects up close it is necessary to stabilize the camera to minimize camera shake.
Good quality travel tripods are generally sold in two separate parts, the legs and the head. Both of these parts can be further broken down into specific areas that should be considered carefully when purchasing a camera tripod. Lets take a more in depth look at what to look for in a travel tripod.
A good quality tripod will be sold as two separate parts, the legs and the head
Tripod Legs
The tripod legs are the first part of the equation. Depending on their cost they can be made of various materials. A travel photographer will be looking for three things, low weight, rigidity and the flexibility to move the legs into awkward positions and angles.Plastic – The only redeeming features of plastic tripod legs are their price and that they will be light. They will however not be anywhere stable enough for a serious travel photographer and will be prone to breaking easily.
Aluminum – This is the standard material for entry level serious tripods. It is immensely strong and rigid however can be quite heavy, an important consideration if using a tripod for travel.
Carbon Fiber – The new generation of carbon fiber tripod legs are probably the best option for a travel photographer, they combine remarkable lightness with excellent strength. They are however significantly more expensive than the equivalent aluminum legs.

Leg locks fall into two categories, twist locks and lever locks. What you choose here is purely personal preference.

Lets look at some typical specifications for a good tripod legs.
- Weight (without head): 2 to 4 lbs (0.9 to 1.8 kgs)
- Height (contracted): 12 to 20 inches (30 to 50cm)
- Height (extended): 60 to 70 inches (152 to 178cm)
- Max Load: 5 to 10 lbs (2.3 to 4.6 kgs)
- Aluminum: $150-300 (without head)
- Carbon Fiber: $250-500 (without head)
Tripod Head
The head component of a travel tripod should be as well researched as the legs. Again, as with many things, you get what you pay for and when budgeting for a tripod make sure to allocate 25-30% of the budget to a head. Lets have a look at the options available.Ball and Socket – This is perhaps the simplest and possibly the most suitable head for travel photography. As it’s name suggests, the camera plate is attached to a ball, which in turn sits inside a lockable socket. This gives a huge range of potential movement and allows the camera to be positioned very quickly. Make sure that if purchasing a ball and socket head you check it’s maximum loading, if your camera is too heavy for the head you run the risk of the lock slipping. Prices for ball and socket heads suitable for travel range from $50-$150

Pan and Tilt – These heads allow you to move
the camera in three planes using separate controls, horizontally,
vertically and also the orientation of the camera from landscape to
portrait. You can lock off one plane whilst moving the camera in
another. These heads tends to be a bit bigger and hence more heavy than a
ball and socket type but often can sustain higher loads and give more
accurate control. The price for a good quality head will be $75-$200

Secondly a built in spirit level is also an extremely useful aid, especially for photographing landscapes and architecture on trips. It allows you to confirm that the camera is level in both the horizontal and vertical plane.

Although not an exclusive list the following are some of the best regarded tripod manufacturers. All have tripods in their ranges that are suitable for travel photographers.
Manfrotto – Produce good quality tripods for reasonable prices. They have a wide range of carbon fibrer legs as well as a huge selection of heads.
Gitzo – Many professionals include a Gitzo tripod amongst their kit. They have an excellent reputation for quality but they are not for the budget minded.
Benro – A fairly new kid on the block, they are a Chinese company whose reputation for quality on a budget is increasing.
Really Right Stuff – Another up and coming company, Really Right Stuff tripods are designed and built in the US and have a loyal following amongst professionals.
Slik – This Japanese company has some very cheap level tripods that are not ideal for travel, however their mid to high range tripods and heads are excellent quality.
In summary, when researching the purchase of a travel tripod, the key elements to look for are size and weight, it needs to be small enough to put in an overhead locker and light enough to be considered for hand baggage. It needs to be rigid, and here despite the extra cost, a carbon fiber tripod will truly come into it’s own and you need to have a good quality head, one that again is not too heavy but gives great fluidity as well as stability.
