Buying a teleconverter over a longer lens for financial reasons can make sense. The very long focal length lenses are considerably more expensive than teleconverters. Using teleconverters to save space (vs. carrying a second, larger lens) when traveling or hiking can be a good decision.

Bought a month ago. Works great with the exception of fast action and sports on my 70200 f2.8 GM OSS lens. Don't let that stop you though! Does well aside from that.
