| LensRentals: Variation Measurement for 50mm SLR Lenses  Quote: Last week we posted an introductory article on how we measure copy-to-copy variation in different lenses. I'll be continuing to publish these results over the next few weeks for prime lenses. We will eventually have a database put up, but I think it's important to look at the different lenses in smaller groups, illustrating some principles that contribute to variation. It's far too easy (and comfortable) to just believe quality control is the answer to variation. There's a lot more to it than just quality control and I think this series of posts will help illustrate that.  | |
