Ok so I own a 60D, and a 600D. I own two SanDisk Extreme Pro 8 GB SDHC Class 10 UHS-1 Flash Memory Card 95MB/s. I plan to install Magic Lantern on both my DSLRs (with there firmware updates). I was wondering lets say if my 60D runs out of memory space, would it be okay to use my 600D's memory card into my 60D's or vis versa? Will Magic Lantern still work with changing memory cards from a different DSLR model? would it change my firmware?
