Sigma is proving to be an amazing success among third-party lens makers yet again. After launching the world’s brightest constant-aperture zoom among its new series of highly-acclaimed global-vision lenses, Sigma unveils a mount-changing service, applicable to new lineup.
With this service, buyers of Sigma lenses can have the lens-mount changed for a fee ranging from $80 to $250 USD, depending on the lens. This lets you switch between supported camera systems: Canon, Micro Four-Thirds, Nikon, Pentax, Sony Alpha, Sony E or Sigma without losing your investment in lenses. With the same announcement, Sigma is also extended their warranty to 4 years.
