A super hot deal, worthy of Black Friday, from authorized Sigma dealer BuyDig via eBay. They have the Sigma Contemporary 150-600mm f/5-6.3 DG OS HSM for Canon for only $679.00. This is the lowest price we’ve seen yet for this very popular and well-reviewed optically-stabilized lens, and it even comes with a free Sigma USB dock.

Sigma is still likely feeling the heat from the recently announced Tamron SP 150-600mm f/5-6.3 Di VC G2 priced at $1399. At just over half the price, the Sigma Contemporary 150-600mm is incredible value.

Authorized Sigma Dealer 47st Photo via Amazon has the Sigma Contemporary 150-600mm f/5-6.3 DG OS HSM for Canon EF for $849.00. This the lowest price we’ve seen since Black Friday 2015. This price does not require any mail-in rebates.

47st Photo is listed as an authorized dealer on Sigma’s site, so this item will come with a 4-year Sigma USA warranty.

Free shipping — both Canon and Nikon mounts are available.

BuyDig via eBay seems to be the only store that gets the concept of a “Cyber Monday Sale”: they have the Sigma Contemporary 150-600mm f/5-6.3 DG OS HSM for only $700.00. This is the lowest price we’ve seen yet for this fantastic lens.

Canon, Nikon, and Sigma mounts are available. The listing clearly states this is a brand new lens with a USA warranty. As BuyDig are an authorized Sigma dealer, this would be a 4-year Sigma USA warranty. This is an epic price, and will sell fast!

UPDATE: As of 8:30 AM, the listing is changed to “Open Box – Closeout”. This isn’t the first time BuyDig has modified an eBay listing after the fact (likely to hide the fact they’re selling below MAP.) Rest assured that the description at the time you purchased is the agreed condition as per eBay rules. Also, BuyDig has a history of listing things as “open box” or “refurbished”, and then shipping brand new items, so this is probably still new anyway. See here, here, here, and here.

UPDATE: As of 8:48 AM, Canon mount is out-of-stock. Congrats if you got in on the deal.

UPDATE: As of 11 AM, looks like Canon mount is back in stock!

UPDATE: SOLD OUT AGAIN! Sorry, this deal is done.

This hot street price deal is back. Last time it sold out in 2 hours. The Sigma Contemporary 150-600mm f/5-6.3 DG OS HSM for Canon is now $899 from an authorized Sigma USA dealer with a 4-year Sigma warranty, and free shipping. Limited quantity.

This lens was only recently made available and is still out of stock at many stores. Compare with $1089 regular price at many stores. Many readers have also expressed interest in the much more expensive Sigma Sport 150-600mm, priced at $1999. We don’t have a street price on the Sport lens, nor will we have one soon, as that lens has been difficult to find.
