Samyang Cine SYCV24M-N 24mm T1.5 (Nikon) for $439

While the Sony Alpha version is a lightning deal, the Nikon version is on sale but not a lightning deal. It looks like it might be a price-match, the Samyang Cine SYCV24M-N 24mm T1.5 lens in the Nikon mount is on sale for $439 with free shipping for a limited time (unspecified expiration date) at B&H Photo (in-stock) and Amazon itself (limit 10; Temporarily Out Of Stock).

Samyang 24mm f1.4 for $370 (Pentax K), $397 (NX), $407 (“Olympus”)

The Samyang 24mm f1.4 manual focus lens for the Pentax K-mount is currently going for $370 with free shipping, with a limit of two per customer at Amazon by Amazon itself. It also goes for $395 for Samsung NX, $407 for “Olympus” (does not specify 43 or M43), and $500+ in Canon/Nikon. When price checking all the different mounts, be sure to pay attention to who the actual seller is. For some of them (eg Sony Alpha) the featured seller is not Amazon itself.
