Hi, I have a Nikon D5000 DSLR. While I love the camera, the lense that came with the camera (a 18-200mm f/3.5-5.6) is just okay and I'm looking to upgrade. I was looking at the "Nikon 18-200mm f/3.5-5.6G AF-S ED VR II Nikkor Telephoto Zoom Lens", but I would like one that has a maximum aperture of f/2.8, since I do a lot of lowlight shooting.Is there a lense that has a smilar focal length range, but is a faster lense? It doesn't have to be from Nikon but it has to have AutoFocus that works with my Nikon D5000 (it's a DX-Format DSLR for those of you who don't know). Thanks in advance.
