Rumors: Sigma 150-600mm f/5-6.3 DG OS HSM Sport lens delayed due to manufacturing defects

I received some information that all Sigma 150-600mm f/5-6.3 DG OS HSM Sport lenses for Nikon mount have been delayed - apparently Sigma corporate pulled back all units that are currently in transit due to a defect that was discovered in the first batch of lenses. The shipments are expected to resume in 45-60 days.

The new Sigma 150-600mm f/5-6.3 DG OS HSM lens is currently available for pre-order at Adorama, Amazon and B&H. Technical details on the lens can be found here.
