No problem
Note that there are some limitations / settings to optimise. Most manga can be converted as-is without any changes. Some bigger western comics (like Storm or other A4 or near A4-materials) you will have to fiddle with as the screen size of the Sony will make the lettering difficult to read; for these I rotate the comics and put them in landscape mode. Calibre can take care of all of that for you, it is seriously excellent software
