I'm currently using an XSi with 50mm 1.8 and the kit 18-55. I want to add 2 more lenses - a wider prime lens primarily for shooting family in tighter indoor spaces, and a zoom lens for shooting wildlife.
I'm considering adding the 28mm 1.8 and the 55-250mm. Combined looks like it'll cost me about 650 dollars.
OR, I could save up a bit more and go with just 1 nice lens, like the 24-105L. Of course it's nowhere near as fast at the wide end and doesn't give me the zoom capability. But it seems like an overall terrific "1 lens" solution to keep on my camera.
