Last evening was this year's version of the concert and since I sold the full frame 5DII back in February, I needed to use crop sensor bodies for the event. The equipment I chose to bring with me was the 7D with the 70-200mm lens and my old 50D with the 24-70mm f/2.8 lens. So, while last year I had 70mm to 200mm available to me, this year I had the equivalent of 38mm to 320mm available.
Last year I used ISO 3200 on the 5DII and this year I used ISO 1600 on the 50D and ISO 3200 on the 7D. I figured I'd need faster shutter speeds with the longer lens despite image stabilization and the 50D is more likely to have unacceptable noise at higher ISO settings, although not by much. All photos were made wide open at f/2.8.
In reality, noise wasn't a problem at all, the biggest issues being the uneven lighting, both in terms of intensity and type of lighting (color balance). Below are four examples, two with each setup.
Focal lengths are the real numbers so you would have to multiply by 1.6 to get what the full frame field of view equivalent would be. The rest of the shots from the evening can be viewed in a gallery with other concerts at http://trulandphoto.zenfolio.com/schoolmusic2014.
