Query: Spectacular Lens

I never thought a prime lens would give me so much flexibility, I thought it'd be the opposite. The small minimum focus distance gives you all kinds of room to work in. I debated for awhile between this and a 50mm, I'm glad I went with 100mm.I don't own any L series, but I own some decent lenses... this one is a step or two above anything I've ever owned. It's ridiculously sharp, to the point where it's something you have to be cognizant about. I could see the spines of my shoot-through umbrella in the reflection on an ice cube in a photo of mine. I didn't notice it until I saw it on full screen and had to shoot it over again. Unbelievable.I can't imagine justifying the paying twice as much for the 100mm L series lens, I couldn't think of a bad thing to say about this lens.
