This chart maps cinema zooms' focal lengths against their speed. It only features lenses designed to cover the full frame format and above. A similar chart for Super 35 lenses can be found here.

Performance Notes

There are a number of features and improvements I wish to make to this chart, however many of which are currently not possible - this is down to inherent limitations of the graphing engine.

The speed and responsiveness of the chart is at present, slow. This is due to the number of points that must be checked when retrieving the corresponding data every time a point is hovered over. At present, there isn't a more efficient way to do this. Please be patient with the chart!

I have also disabled a feature in which the highlighted point is brought to the front, as this has a significant impact on the chart's speed. Therefore some points will remain behind others, even when highlighted.
