Here are some sample photos from the upcoming Light Lens Lab Cooke Speed Panchro 50mm f/2 SP2 lens for Leica M/LTM, Canon EF, and PL mounts - please note that this was a prototype (if you are interested in purchasing a LLL lens, contact me here and I will forward your request to the company - LLL does not have a website but they do ship internationally):
Update: PopFlash is now the official distributor of LLL (Light Lens Lab) lenses in the US - check out the LLL lenses listed at their eBay store.
