Sigma Japan temporarily suspended orders for the 85mm f/1.4 DG DN Art & 56mm f/1.4 DC DN Contemporary lenses for Sony E-mount. A quick check shows that both lenses are currently in stock in the US:
Apology regarding the supply status of “SIGMA 85mm F1.4 DG DN | Art” and “SIGMA 56mm F1.4 DC DN | Contemporary” for Sony E-mount
Thank you for using Sigma products.
We have received orders for some lenses for mirrorless cameras that exceed our expectations, and production is not able to keep up with demand. Therefore, we will temporarily stop accepting orders from today. Also, it may take some time for the products you have already ordered to arrive at your doorstep.
We will inform you again on our website regarding when we will resume accepting orders.
We apologize for any inconvenience caused to our customers and related parties who are waiting for the product, but we are currently working diligently to produce it, so we ask for your patience.
We appreciate your continued patronage of our company and our products.
