Sigma has announced its 24-70mm F2.8 DG DN Art lens for Sony E-mount and Leica L-mount has been delayed due to unexpected demand for the product. In a statement on its Sigma Japan website, the company explains that it is working on producing the lens, but that it will take additional time for the model to be made available.

Sigma's latest Digital Neo lens was announced in early November with plans for it to arrive through authorized dealers in the US starting in mid-November. The lens is currently listed for preorder/backorder on Adorama and B&H Photo for $1,099, a price that's considerably lower than competitors' alternatives.

That low price likely contributed to the high preorder numbers. Sigma doesn't provide an estimated shipping date for the backordered lenses, instead asking that customers 'remain patient' during the delay. Interested future buyers can enter their email address on B&H Photo's website to receive an alert when the lens is back in stock.
