Is it possible to flash the firmware of a camera to add features? I have an older DSLR from Canon. Over time Canon has introduced features for example 5 photo bracketing instead of 3. When I look at the newer models, the specs are almost the same. The only difference being the sensor. This should not affect things like bracketing and custom focus options.
This leads me to believe that many features are simply software in nature. I know I can download firmware updates for any camera but switching from one firmware to another via update seems very risky and I doubt the automated software will recognize it.
I have loaded new bios on GPU's to get extra performance. Is there a way to do this on a camera without bricking it?
