I think I made a good decision buying the T2i with a kit lens. This lens pairs well with the T2i and the combo is very light and portable. When I hold them in my hands, one word comes to mind: Fun! It's very different feeling in usage when a 50L or 85L lens is mounted on it.
The lens turns out to be quite a good performer. Surprisingly sharp when stopped down a bit, although, as with most entry level lenses, distortion is not well controlled, especially at the wide end. The far edges are actually very respectable. I have included one 100% crop on the satellite picture. This picture was processed in DPP. I played with DPP a bit today and I think I am getting a hang of it. Still not quite used to it yet, but the quality and colour fidelity is much higher from DPP than the in-camera jpeg.
I do wish the range is a bit longer, say 18-85, but then of course there is the EF-S 17-85mm. It will be sufficient for most occasions, though.
Discovered an oddity. The ISO on the T2i can only be manually changed in whole ISOs, like 100, 200, 400, etc. But, if you use Auto ISO, the camera will use ISO 320, 640, etc. Now, why not give us the same thing when we want to control the ISO manually?
I really do like the 18-55mm IS lens. I am actually happy with it. Now only if I can get a hood for it.
Still working on the focus test...
