[QUOTE="Fortkentdad, post: 640360, member: 24285"] With focal length I've learned that the smaller the number the bigger the difference each increment makes. In other words the difference between a 20mm and 24mm may be 4mm but the difference in view between a 20mm and 24mm is greater than the difference in view between a 50mm and 60mm. 84 to 73.7 degrees of view from 20 to 24. A 15mm like this macro would be 100° wide where as 50mm is 39.6 and adding 10 more mm gets you to 33.4 or about 6 extra degrees for 10mm more focal length. While those 4mm extra between 20 and 24 adds 10° more FOV. This is from a chart I found over at Nikonians: [URL]https://www.nikonians.org/reviews/fov-tables[/URL] It is all in the "FOV" or how many degrees wide you view will be. [/QUOTE]
