Today, I was asked to take photos at a concert this coming week. It will not be for money or that. They just want me to take photos to help them remember the concert so I agreed to help. I have a Nikon D90 and I have only been shooting it since late July or so. I am going to bring my 1.8D 35mm, friend's 2.8 70-200 VR and possibly my 14-24 2.8. I don't know what the lights will be like or that. I am going to have a test run on Tuesday. What I am mostly wondering is will I be able to use my Nikkor 105mm 2.8 Micro in a concert? I have shot some nice portrait shots in day light but I am wondering how it will work in possibly a low light setting. Has anyone tried shooting with it at a concert? I understand that I will have no zoom so that will be a draw back but it would force me to think more about what and how I am shooting it. Should I even bother bringing it and just stick with the 70-200mm? I would appreciate any info. Thanks.
