I have been working through the development of a lens screening procedure for the last couple of months. For the past three days, I’ve been writing it up, and have posted it here. It’s far from complete, but it’s ready for a few people to try using it to test their own lenses. If you are willing to be a guinea pig, I’d appreciate it if you’d test a lens or two and let me know how it came out. I’m sure that there are places where I could be a lot more clear in my instructions, and if any of you would help me find them, I’d be grateful.
Feel free to use the comments feature to give me feedback. And I’ve you find any poorly-assembled lenses in your collection, I’d like to see your raw files.
