Firmware update for Sigma 18-50mm DC DN fixes aperture problem

David Garth said:

Many of us have noticed that this new lens doesn’t set the correct aperture on Fuji X cameras when set to f2.8, f3.2 or f3.6 and zoomed to 40-50mm. They all are actually at f4 even though the camera readout reads differently

There’s a brand new firmware update that totally fixes this issue.

BTW, I love this lens. --

Cant believe we have to send the lens to Sigma for something as simple as an update.

You don't have to send it back...update process is exactly the same as for a native Fujifilm lens...updated mine without any issues.

They should come up with something to fix the zoom rotation next. I hate how it rotates the "Canon way"
