Wow, did you get this up in the 10 day time period since they announced closure? It took me 2 months for my project. I think I should really look into just scraping / importing the lens data at this point for cameralenspicker.com. I’ve been hand inputting the data… but it’s just too slow.
The trick here would be to do a static scrape of all of dpreview, and post it on archive.org or similar. It's copyrighted, but I can't imagine enforcement of a discontinued resource.
Amazon is imploding a huge amount of value here.
