Ho to Make a Wide Open Huge Lens • How Does it Works

Video Description

AMZN: diaphram: https://amzn.to/41SefNE Hi guys, today I'll show you step by step how to build a large lens at home for a camera or a video camera. In fact, in today's project I decided to recycle and reuse an old lens taken from a cinema projector and once printed in 3D, a suitable container I took exactly the various measurements of the various lenses needed for this project. Obviously for the realization of this project it was essential to take the various measurements and especially that of the . of focus of the various lenses so as to be able to match one to the other and be able to obtain a fairly precise result. Considered in this lens it will be a fixed lens to be mounted stable in my laboratory, so I do not need to have to focus quickly on the various subjects because in any case it will be positioned in a studio where the lights are constant, the distances between the tripod and the subject will always remain the same and so I wanted to try to build this prototype myself Obviously the result is decent, but not excellent. This is certainly due to the complication of focusing, since I am the only one to manage everything. In any case, I would say that the purpose of this video is not so much to have an optimal and functional lens for my projects, but more to seize the opportunity and understand together starting from scratch, why a photographic lens is built in this way, what are the components that compose it and why it works in this way, rather than another And what better method to learn something than to build it by hand starting from scratch Obviously there is still a small margin of improvement due to this slight lack of sharpness of the framed subject I will have to experiment in the future with the addition of additional lenses or adapters capable of collimating and perfecting the image performance Let me know, below, in the comments, how you would improve the lens in order to obtain a better frame Also let me know, if you have to correct something that I said in the steps in which I draw on the various lens diagrams
