Seeing how the 7D performs under stadium lighting. Here’s a sample image at ISO 5000 and then processed via Lightroom. The top image shows the full frame and the second image is the crop and the third image is a 100% view. It’s not as clean as a 1DX but it’s certainly acceptable. I also found AF Area mode isn’t giving consistent result, possibly because the motor in the 7D isn’t driving the lens as quick as the 1D. Results using a single point with 4 point expansion is better. More testing to come.
