Sigma 65mm f/1.0 Reportedly Coming in September

If this pans out, a Sigma 65mm f/1.0 with autofocus would be genuinely interesting — portrait shooters and low-light event photographers would have a native-mount alternative to the Mitakon/Voigtländer manual-focus options that actually hunts focus for them. But this is one leaker, no specs beyond aperture, and September is vague. File it under 'watch this space' rather than 'clear your calendar.'
