50mm is what photoscan assumes when you input photos with no exif data, so 50mm is kind of the baseline. Realistically the lens you use can (and should) vary depending on what you're going to scan. Lens quality is paramount, fixed lenses generally crush zooms. I use 40mm fixed lens on Canon 100D cameras for medium sized objects, works great and you can get the kit in your price range, comes with a zoom lens too if you want to do different sized stuff, the quality drops off some, but photoscan doesn't have a problem with it, and for game rez textures it's much more than good enough image quality wise. You may see some dropoffs in quality of the sparse point cloud towards the extremes of a telephoto lens, but photoscan is surprisingly versatile. It has much more to do with the way you take the photos than the quality of your hardware in my experience. I compared my $500 kit (100d/40mm) with a $3500 kit of an a7r with a zeiss fixed 50mm lens and the quality of the finished models for game purposes was almost identical. I sold the a7r, Photoscan had a better time matching points with less images with the 36mp camera with one of the sharpest lenses in the world, but it was totally not worth the price difference imho, unless you have the cash laying around. You can just take a few more pictures with the lower resolution camera to ensure a good alignment. That's my $.02.
