The Canon V-25 has a design similar to the V-10 and V-20, but it's a MSX2 entirely in white color. Its big disadvantage is the limitation of the VRAM to 64kB, which makes it impossible to use SCREEN 7 and 8. Also it lacks the floppy drive that was usually present in MSX2 computers.

For the photography fans, this machine is recommended to be used with an innovative digital Interface Unit DMB between the computer and the Canon T90 Single-lens reflex (SLR) camera. DMB-90 means Data Memory Back 90.
