There are some scarily good Halloween deals on Sigma lenses going down at B&H Photo this week, perhaps the standout bargain being a phenomenal price on the much vaunted Sigma 35mm f/1.4 Art. In total, 73 lenses are on sale for just four days total, so you should probably check out some of these deals.

If you get your order in before October 31, you can pick the Sigma 35mm f/1.4 Art (Sony, Canon, Nikon) with a savings of $200, bringing the price to a mere $699. If you’re a Sony shooter, that makes it $50 cheaper than Sony’s own 35mm f/1.8, making a faster, arguably sharper lens even cheaper, assuming you don’t mind the added weight given that the Sigma is more than twice as heavy.

If you’re pondering the completion of your holy trinity, you can scoop up the Sigma 70-200mm f/2.8 DG OS HSM Sports Lens (Canon, Nikon) for a mere $1,259, giving you a saving of $240. In addition, the Sigma 24-70mm f/2.8 Art (Canon, Nikon) is down from $1,299 to $1,079, offering a terrifying discount of $220.
