Option 3 - Monopod That Almost Acts Like a Tripod
Koolehaoda Monopod With Feet
The Koolehaida monopod has folding feet and cost around $50. The feet lock into open position fairly securely and supports my Canon 5d Mark III along with a 70-200mm f/2.8 lens.
The consolidation of camera tripods and monopods into one single accessory to carry seems to be becoming more popular. Designs have improved a lot over the last 9 years. Rather than just a geeky attempt at making something new, designers have actually built in valuable features that serve photographers.
