Query: A Must-Have lens

This lens is completely different from the 14-45 kit lens. Not in the same class at all. This lens provides better color saturation, more accurate and pleasing tones, better contrast, faster focusing, and a wider aperture. In general, this will give you considerably better pictures than your kit lens. How much better?On a scale of 1-10, (1 being point-and-shoot lens/image quality and 10 being outstanding), I'd give the kit lens about a 4 and this lens about a 9) The 10 slot is reserved for the 11-22mm lens which is crazy sharp! But that's another review for another day.It's not all about image quality though. There's a lot to be said for the wider aperture size of this lens. You'll be grateful for a faster lens when you're taking those tricky-lighting shots, or when you want to speed up your shutter to freeze motion, and you're indoors with poor lighting. That wider aperture will save you!Seriously, get this lens. You won't regret it when you see how beautiful your pictures are.
