You may want to qunatify, your photographic experience. But, in reality I can probably save you a lot of time. Leica Lens as a general rule test poorly. In comparsion to the other other major manufacturers. What you have to do is to take pictures and see with the different lens and see what you really like. Leica lens are designed to reproduce a scene while maintaining, the proper contrast ratios. While other lens are designed to reproduce charts and graphs, Leica's tend to photograph life , the way it's supposed to look. John N3BVH
