Tom you should shoot above 3200 more often as your just barely scratching the surface with the 5diii at 3200. For me 12,800 is very useful and even 25k in a pinch and not printing terribly large.
Brilliant shots, even regardless of the ISO. The composition is stellar imho, quite inspirational.
7d owners steer clear,this thread is pure pain.
Nice shots though
Thanks for the kind words!
Yes well I came from the 40D then 7D. The 7D I thought everything but IQ was better, but wasn't satisfied. High ISO was better but 3200 was still about its limits and 100-400 seemed quite noisy.
So I got the 5DMKIII and I am very happy with it.
Believe it or not the first time I went out with it shooting some landscape, the available light wasn't great for small apertures and was shooting 1000-3200ISO at F11-16. Surely for landscape the worst idea....?
Have a look at this:
