Five things to look out for

1

A monopod must be able to support the total combined weight of your camera/lens/ accessories setup.

2

How high do you need your monopod to go? This will depend on several factors, not least how tall you are!

3

Monopod legs will be separated with twist- or flip-style locks. Twists tend to be more secure, but flips are faster.

4

Some monopods will have additional flip-out feet for a more stable support, or a fixed rounded foot.

5

Grips on cheaper monopods will likely be foam, while more expensive models will use textured rubber.
