Hello Andy: Yes that's it. The 180mm allows more working distance at a given magnification e.g. 1:1. So you can stay further away from the insect (or snake!) and you are less likely to frighten them away.
I agree with Saphire that tubes are a good way to go beyond 1:1. I have Triplus autofocus tubes. They retain AF and metering on Nikon cameras. Build is okay I suppose.
