Having had no time these last few days to get out on an evening I decided to sort out the shots I took last time out. The details captured by the 7D at ISO400 stunned me once again. I decided, as I had no closeup, to crop one of the shots, see how it came out. This is around 50% cropped, so still 2500px on the long side. I am impressed, I do hope in Africa I need not use ISO800 as less than that you have seriously brilliant IQ.
