In a post on Sightron Japan’s website, it has announced that the Laowa 4mm F2.8 Fisheye lens for Micro Four Thirds (MFT) camera systems has been postponed in the Japan region.

In a very brief notice (translated) on its information page, Sightron says the lens, which was set to be released this coming Friday, has been delayed. The machine-translated version of the notice reads ‘since there is a possibility that a problem individual was mixed, we decided to postpone the release.’

Based on that translation, it seems as though a number of lenses had issues, but Laowa couldn’t pinpoint down exactly what lenses were affected and are therefore going back through and testing the units that have already been produced.

Sightron Japan says ‘details regarding the release date will be announced as soon as they are determined.’ It ends the post by thanking interested parties for their understanding and patronage.

Update (September 11, 2019): This article originally misstated the relationship between Sightron Japan and the Laowa brand. It has been updated accordingly. We have also confirmed this delay will only be affecting the Japanese distribution of this lens.
