Antwoord op "Where can I buy a replacement lens for a Casio EX-Z70"ebay The EX-Z70, EX-Z75, And EX-Z77 all use the same lens. The EX-Z60 and EX-Z65 also use that lens. Anyone of those lenses will work. If you get a Z60, Z65 or Z77 lens, you with have to switch the CCD Sensor over to the new lens, but the Z70 and Z75 have the same CCD. It's Easy.
