You really need to read about SEMA. The Specialty Equipment Manufacturer's Association has gone to court and battled warranty issues with car manufacturers for years. As a result, aftermarket parts cannot void a warranty. If you put a supercharger on an engine, and you blow the engine, you are responsible. But, if you put a K&N airfilter on your car, the car dealer cannot deny warranty coverage.
The same holds true with your camera.
Aftermarket lenses, batteries, flashes, filters, remote control or anything else and the camera body goes POOF, Canon has to PROVE that the aftermarket component was the culprit. Now, if you use a flash that has the wrong voltage, you could blow your camera, and it would be your fault. You have to use an acceptable substitute.
No one can simply deny warranty coverage. That is against the law. Otherwise, Canon could force you to buy a Canon tripod, monopod, backpack, and just about anything else. You'd be driving your Toyota with Toyota tires, and nothing else. You'd have to put in Toyota gasoline. You'd have to use Toyota wiper blades, toyota washer fluid.
Tampering with software is a gray area. I'd bet Canon would dishonor the warranty if they found hacked software. Frankly, DMCA prohibits anyone from reverse engineering that software. Does Canon really care? We don't know, but I'd be wiling to bet that someone from Canon is aware of this and they learn as much as we do... at least the next time, they know what to change if they want to keep the public from messing with software.
Is the DMCA enforcible overseas? Not really. Is there any risk in downloading the image? Not sure. If your camera dies with hacked software onboard, you'll have to hope that they either can't tell, or that they don't notice.
And, don't leap to conclusions on aftermarket parts and warranty coverage. Know your rights.
Yeah Gregg,
And using non-canon accessories will also do the same... so I guess
no non-Canon lenses, batteries, hand straps, cases, flashes, or
tripods for you.
