Making the Ultra Lens - 2600mm f17 lightweight ultra-long focal length lens made of PVC and ABS

This video shows the making of the Ultra Lens. The name is in jest but the project is a worthy one. My goal was to make a lightweight ultra-long focal length lens out of cheap materials that would throw a high quality large image circle. Success in spades. Watch till the end for the ultra big image circle and please share with your fellow homebrew lens nerds.

Statement on disabled comments as of 8/2024:
In an effort to focus more on my work with reduced distractions, I have limited my social media usage and disabled engagement features where possible -- this includes commenting across all social media that I use. When I share content, I'm doing so mostly as a record for myself and to share with those who follow my work in a bulletin board type fashion. While I appreciate the responses of my viewers, the nature of how these platforms work means that I am frequently inundated with one word comments, emojis, and spam. I spend very little time online and since I am not creating content to chase engagement, I have found that the best way for me to respond to meaningful questions and discussion is directly via email. I prefer 1:1 communication and this helps me further reduce time online, make more meaningful connections, and increase time spent in the studio. Those who follow my work understand how important this is to me. So, if you have questions or would like to share something with me, please feel free to email me through my website. Thank you.
