Sigma's mysterious countdown to 'liberation' revealed to be a service offering lens mount conversion to Canon, Nikon and more

The speculation is over on Sigma’s countdown and it doesn’t look like anyone quite got it right. Sigma Poland has unveiled its new lens mount conversion service.

‘Change your mind. Change you mount,’ the site announces. Slight translation issues notwithstanding, this is exciting news: the firm is offering users the chance to change the mount of their current Sigma lenses to another mount of their choice

The decision to change your brand of camera can be a tricky one, and it’s further complicated by the fact that doing so will immediately make all of your lenses unuseable. Sigma’s new service could render such painful decisions a thing of the past.

The mount conversions on offer at the moment are Sigma, Nikon, Canon, Pentax and Sony, as well as Sony E-mount and Micro Four Thirds. Be aware that only newer lenses from Sigma’s Art, Contemporary and Sports ranges are currently the ones available for conversion – the FAQ explains that they’ve been specifically engineered to be compatible with MCS. There’s a complete list of eligible models on the website.

This service could open up a lot of new creative possibilities and we’re excited to see how it takes off. It’s due to begin in Japan on September 2nd, and you can find out more at the newly launched website.
