Another option for this focal length range is the Tamron 28-75 f/2.8.
Whilst it is longer at 28mm vs 24mm, it's not a huge difference in focal length.
This lens can be sharp if used correctly, and brand spanking new is the cheapest of the lot in this lens genre ... usually in the $400 price bracket.
It's small light and a good performer. It has it's quirks, but on an Fx camera it works quite well.
