the 'We cant fix it you have a go' option?
That's just a tad too cynical no?
Seems like a good idea considering the problem of having to send the old lenses to Sigma for a rechip.
The new Sigma Optimization Pro software and USB Dock are designed exclusively for these new product lines and will enable Sigma users to connect their lenses to their computers to update lens firmware and fine-tune focus parameters via easy-to-use, on-screen controls.
If these lenses work well, looks like 1st party manufacturers will have to step up their game yet again... Or lower their price.
