The 180 is a beautiful lens. For insects it is the lens. Also prefer the longer focal length to 100 for flowers. The back ground goes so smooth and simple when out of focus.
When my pentax 200 macro arrived I was surprised how my shooting style changed over the 100 macro. With the 100 there is a lot of hand held/ flash used to get the bug before it runs. Can do that with the 200 but don't have to often. The insects just sit around while I shoot from a tripod. Out of their fear distance so there is time to shoot tripod and available light. Never expected this wrinkle. The larger macros are very hand holdable - especially with flash. Just takes practice.
