Cameras and audio calculator
Lens focal-length planner
Photographers matching a prime or zoom to subject. The decision this page isolates is narrow on purpose: translate subject distance into a focal-length class. Payload, channel count, and distance decide the class. A sample photo does not.
This page produces an explainable category or size so options can be compared without a product ranking. The calculator does not rank Sony and Sigma. It produces an explainable class so Sony FE 24-70mm f/2.8 GM II, Sigma 35mm f/1.4 DG DN Art, and Sony FE 70-200mm f/2.8 GM OSS II can be compared as examples of that class.
The working method is: Convert the inputs into a published planning class using the method on this page, then compare official product pages that match that class. Planning notes are grounded in CTA. This page does not quote a price or rank a brand.
