Nice job man.
That 50G is real sharp. A friend of mine has that, I have the 50D and there is a big difference on glass resolution.
Wide Angle huh ... hmm.
I suggest you look at the Tamron 17-55 2.8, usually find them between 350-550.
Or the Tokina 11-16 2.8 Great wide, but a bit more expensive at 450-650.
But both are great.
The Nikon Wides are quite more expensive, even the DX models (DX for the Nikon/Nikkor Crop Sensor Lenses)
