DK-Optic Impastolite 50mm f/1.5 렌즈 출시 (M mount)

DK-Optic is a new Chinese lens manufacturer, and they will soon introduce a new Impastolite 50mm f/1.5 lens for Leica M-mount (already listed for sale on eBay) – this is a modern reproduction of the legendary vintage Dallmeyer Septac Anastigmat 50mm f/1.5 lens:

Background on the Original Dallmeyer Septac

The original Dallmeyer Septac Anastigmat 50mm f/1.5 dates back to the 1950s (with prototypes as early as the late 1920s or 1930s) and was produced by the British optical company J.H. Dallmeyer. It’s a rare cine and still photography lens, originally an option for cameras like the Ilford Witness, and is considered one of the fastest and most coveted 50mm lenses from that era. The design is a 7-element in 4-group Sonnar-type anastigmat, based on earlier innovations like the 1938 Simlar lens. Vintage examples exist in uncoated and coated (e.g., DC coated) versions, with the uncoated ones being particularly rare and prized for their “oil-painting” style bokeh, soft melting highlights, and three-dimensional rendering that doesn’t match modern sharp optics. Originals are extremely scarce, with auction prices reaching around £25,000 (about $32,000 USD) for well-preserved copies.

Dallmeyer Septac Anastigmat 50mm f/1.5 lens 를 복각해서 내놓은 듯 합니다.

이베이 판매가격을 보니 500만원이 넘는 듯 한데..가격이 만만치 않네요…^^;;;
