Comparing Photographic Lens Weights

As part of a current project I have access to (mostly complete) metadata on over 200 lenses across a range of consumer vendors. As part of a test to visualise discrepencies in the collected data I managed to construct a few plots of basic metadata over focal length.

As a quick preview to a future longer analysis I’ve thrown in the initial plot of lens weight vs. minimum focal length below. Tamron has been omitted as their weight data is still pending.

A couple of quick points:
