Canon press release: MELVILLE, N.Y., September 12, 2023 – Canon U.S.A., Inc., a leader in digital…
Another breakthrough by the Magic Lantern team. 1/2 stop more dynamic range on the Canon EOS 5D Mark III – 15 stops of DR are now possible on the 5D3! The image above, posted by a1ex on Twitter shows the increase at different ISO settings.
The EOS 5D Mark III will soon get what ML calls a “sensor update”. Not much is known so far, everything is in a very early development stage, but a sensor update via firmware sounds very cool. The trick was to figured out the digic registers that have to do with ISO.
User Marsu42 of Canon Rumors‘ forum did some tests and writes:
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.
This new feature will soon show up as nightly build. Caution is advised: this is software at an early development stage, use the necessary attention and do not try it if you are not sure what you are doing.[via CR and P5D]
