The Sunshine coast classic rally came past our house today. Lots of nice cars and a lot of noise. The Canon proofed to be the right choice for this task. Not so much because of the autofocus - it cetainly helped, but more so because I could use the 800 Isoand achieve sufficiently short shutter speeds. The M8 was easier to use because of the viewfinder, you could follow the cars much easier, but the speeds I had to use were too long. This is the slight corner opposite our drive way.
