Nope! I have been using ML for over a year for dual ISO and focus stacking and I have had ZERO problems. The thing to note is that I have been using one of the nightly builds and it is stable. I have not used it for movies so I can't vouch for stability there but I am sure there are some on this forum who could give you an opinion on that.mabye, but i often wish i could somehow get just 1-2 stop more DR out of my canon RAWs.
would not give me a proper exposed outside but made things way better.
it´s seems nikon can do that without a problem.
then look at the 5D Mk3 picture in the review, they are unusable.
Have you tried MagicLantern's DualISO?
Use of ML can damage your camera and they say so. It is not something that just "anyone" or "everyone" should use.
