When it comes to lenses, we spend a lot of time obsessing over spec sheets and test results. But, it’s easy to neglect the engineering wizardry involved in creating a lens. We snap them onto our cameras and shoot away, but there’s a crazy amount of science in action and this video from Filmmaker IQ does a great job explaining it.
The video is 25 minutes long, so it’s a bit of a commitment but it will give you a better understanding of exactly how your lenses work. Personally, I love stuff like this and I honestly think that knowing the science behind your gear can help us use it to its full capabilities.
