I'm looking for a macro lens and am almost ready to pull the trigger on the 100 L IS.
However, recently I've been reading user reports about noisy IS, and that the lens makes a rattling sound.
Almost all reviews I've read are positive and don't seem to mention this though. However not articles about this lens are a bit dated now.
I owned a sigma 17-50 for a brief period and that lens was quite clunky, I found it quite annoying.
What are people's experience with the 100L macro? Is is noisy / clunky? How does it compare to more modern lenses that are released today? Are there better options for macro now? Or is the 100L macro still considered a top choice?
