Kelly Grannell said:At $300, you'll get a decent entry level lens. I strongly recommend Sigma 18-125 lens. It's a good walkaround lens. Now if you're talking about specialty lens that will actually WOW you, then you'll need lenses such as Canon 50 f/1.8 (that's close to $100), Canon 70-200 f/4L (around $800, I think), or the super-wow Canon 70-200 F/2.8L IS (around $1,800). There are other lenses such as Sigma 17-70 f/4.5 for around $400 that's also very good. However, none of the lenses can be considered as walkaround lens (other than the Sigma 18-125).
I personally use the Sigma 18-125 when I'm travelling abroad, and use the 70-200 f/2.8L IS when travelling locally.
Kelly,
What would you typically use the Canon 50 that will WOW you for?
