Canon legal responseCanon legal responsePosted Jan 12, 2013 23:40 UTC (Sat) by man_ls (subscriber, #15091)In reply to: Canon legal response by giraffedata Parent article: Testing Magic Lantern 2.3 If the new software is GPL, and reverse-engineered, I don't see how it can be a derivative. It is a new piece of software (or firmware as they are called in cameras) that happens to use the internal processor of a camera. The parts of the original software used are just for interoperability, which is usually legal. As to the contract of sale, I have never seen any of those for consumers. I just sign on the credit card slip. Perhaps there is a shrink-wrap agreement or something, but I have not seen them on cameras either. How can a court prevent me from doing what I want with my purchase. Also, the original project is not modifying anything, just distributing software (which is not a derivative of the original). Is Canon going to sue its customers, following the RIAA strategy? I suspect the strategy would be just to sue the Magic Lantern project on whatever grounds allowed by the most absurd legislation they may find, and make them waste time and efforts in the defense. And that this move would not grant Canon much love either.

Canon legal response Posted Jan 13, 2013 2:48 UTC (Sun) by giraffedata (subscriber, #1954) [Link] If the new software is GPL, and reverse-engineered[1], I don't see how it can be a derivative. I agree that the derivative work thing doesn't stop anyone from installing Magic Lantern. I was just commenting on the statement (second hand and anonymous) in the Canonrumors review of the expensive camera that Canon would use legal measures to stop people from converting the cheap camera into the expensive one. You're pointing out that if Canon's power to do that is based on copyright law, then the Canonrumors article is irrelevant to the LWN article about Magic Lantern.
Perhaps there is a shrink-wrap agreement or something, but I have not seen them on cameras either. Have you bought a camera with $4000 worth of software restrictions (price difference between the expensive and cheap camera)? It's considerably more likely that a purchaser would have to make certain promises to get one of those than to get typical consumer items. Trying to make sense of the "Canon would bring the might of its legal team" statement, I'm surmising that Canon does in fact require this kind of contract.
Canon legal response Posted Jan 13, 2013 10:45 UTC (Sun) by man_ls (subscriber, #15091) [Link] In fact I have never bought such an expensive camera, by an order of magnitude. Perhaps some lucky reader can enlighten us about whether Canon really places burdens before its customers in the form of contract agreements.Note that the original camera was not sold with software restrictions: the expensive new model is just now being released.

I've never seen or heard anything of the sort. When it comes to "making sense of" the legal-might quote, I think it's what it appears to be: an off-the-cuff remark. Perhaps intended to intimidate; more likely uttered by someone without a studied understanding of copyright law and reverse engineering -- particularly as applied to firmware replacement hacks. Nate

(i have used magic lantern on a 5DII, but not looked deeply into how it is implemented).
Magic lantern runs along side the original software. The original interface is still there, but hooks are added in, so that additional information can be shown in screen, and buttons can trigger additional features.
see the main picture at http://www.gizmag.com/magic-lantern-canon-eos-7d-cracked/... for an example.
I am not sure i they achieve this by creating a firmware that contains bits of the original software plus extra functions. Or whether magic lantern is more like an extra application running on the system.
