• CLeW strives to provide a comprehensive and reliable online resource for professionals and enthusiasts in the motion picture industry. It's an ambitious project that I started as an effort to share my knowledge and experience. We strive to be the go-to destination for information on cinema lens manufacturers, their lens models, and the features and history of the motion picture lens industry. By presenting accurate and up-to-date information in a user-friendly format, we aim to foster a greater understanding and appreciation of the art and technology of cinema lens production and use.
  

If you have any questions, suggestions, or need help with anything, don't hesitate to contact me anytime.

Stay focused, lens geeks!

• We've deployed a Tools & Data section to CLeW. This will be a space for convenient resources for all CLeW users to employ starting with a Macro Extension Tube Calculator for generating practical focusing distances when using an Extension Tube.
• The Lens Database page has been revised with a more streamlined organization method (alphabetical). The older table style was more compact, but proved too challenging and time consuming to make minor updates to. The new layout provides an alphabetical table of contents on the right-hand column.
• Several newly released lens models have been added including Sigma, DZOFilm, Cooke, and more! Browse the Lens Database here.
