>it's very hard to figure out a lens to get that will work with the Pi, look right if mounted from around 2 to 3 feet away This is why I purchased a Commonlands lens instead of a variety of others (including Arducam). The owner has gone through the trouble of taking a consistent photo of the imatest pattern for each lens they are selling, i.e. this: https://cdn.shopify.com/s/files/1/0273/9273/7398/products/cellphone-4-2mm-m12-lens-14641003233398.jpg?v=1601414029 https://cdn.shopify.com/s/files/1/0273/9273/7398/products/ce... and measuring the amount of distortion and listing it as part of the specs. That gave me a really good idea what the picture was going to be like before I purchased the lens, and the product I received accurately reflects what was shown in the image. It also showed me that even a small amount of distortion (2%) was too much for my use case.
