Tunnel View with half a dozen other Ansel Alikes, and you know how many elements and in what groups my lenses are made up of, what is it that you can tell me about my lenses or how they will see?&nbsp;

Likely nothing you don&#39;t know from using them. OTOH lets say you walk into a little shop one morning. It&#39;s a junk shop but in one corner is a pile of old lenses. Having a vague idea of what each design can do makes it easier to find a deal. Maybe you&#39;re looking for a lens to cover an ULF camera. Now if you aren&#39;t looking to buy a lens I&#39;m not sure any of the trivia really matters. The lenses you own are best tested on a camera with film. Two lenses from the same manufacturer made the same year can vary.
