Well I finally decided to get the 24-70 mm f/2.8. I exchanged it with the 24-120 mm I had before. With the 24-70 I will loose a bit of the zoom, but I'm at least obtaining a lens that is better in low light, quieter, nano coating, and sharper. Normally I never use the zoom anyway, so I am not loosing much anyway. Plus, I have a 70-300 that I can stick on if needed. Soon, I will also get the 70-200 f/2.8 so I can use that in low light, and because it has vibration reduction.
Anyway, I will be using the new lens this weekend for a wedding. So I hope everything goes okay with it, and then I will be posting more images here online.
