Breakthrough at Magic Lantern, imho this elevates it to a must-have and makes Canon look really stupid: They at last figured out what the digic registers having to do with iso are, and by fine-tuning them your camera now gets an additional 1/2 stop and more of dynamic range, no strings attached. Just use +1/2 stop of ec (ML also has ec in m mode, just like the new 1dx fw) and you're done.
This means that for example on 5d3, iso 800 with ML has more dynamic range than iso 100 with Canon :-> ... and at high iso you're getting 7% more dr which is nothing to sneeze at, esp. since it builds upon Canon's advantage vs. Nikon: d800@6400 = ~8.3 & 5d3@6400 = ~9.4 ev making good ol' Canon the superior sensor for low light high contrast shooting, esp. the newer 6d.Code: [Select]
5D3 Canon ML
100 11.16 11.55
200 11.08 11.52
400 10.96 11.41
800 10.76 11.2
1600 10.32 10.78
3200 9.72 10.2
6400 8.78 9.35
12800 8.01 8.59
Read all about it here, test modules are about to be out, next coming to a nightly build near you! Here's the dev thread if you want to follow the development: http://www.magiclantern.fm/forum/index.php?topic=9867.msg96529#msg96529
Last not least, in combination with the dual_iso module ML now allows you to cover 15 stops of dynamic range in one shot w/o bracketing (by interlacing the shot with two iso values, meaning there's some loss of fine detail in the extreme highlights/shadows). If you feel exposure challenged, you can use the ettr module to automatically set the exposure so it covers exactly the dynamic range of the scene with optimum snr :-)
Great report. I havent had a chance to try any of this. Wonderiing what effect all of this has on drive mode frame rates?
