I used the 100mm f2 lens with the Canon T2i. I originally owned this camera for a few months after it was introduced, but didn't like image quality and sold it.. Now that I have a chance to use it again, I miss how responsive the camera performs; more so that the Sony NEX-5N, especially on image playback. Still, the sensor in the NEX-5N is much better than the T2i with lower noise and more dynamic range.
