But why is this a good combo? Please explain to a novice photographer haha.
Because you've got some different focal lengths covered this way:
- Wide (10-22mm)
- Medium range (50mm)
- closer range (100mm)
And they're all reasonably fast, so you should have some glass to use no matter what situation you're in. Unless, of course, you're planning on going to Yellowstone and shooting grizzlies from 500 yard away, but those lenses are a little out of your $1k budget. :-)
