This image was taken at around 19:30 on Monday at a wet, windy and not that well lit Newquay station in Cornwall. It's not exactly the final shot I was hoping for when I set out earlier in the day, in rather better weather, to travel to all five terminal stations on the Cornish rail network, but it does illustrate the high ISO capabilities of the 5D3.
5D3 + 24-105 f4.0L @ 24mm, 1/6 second, f5.6, 10000 ISO
