This interchangeable lens mount enables professional broadcast and studio lenses to be used seamlessly on the URSA Cine platform, opening the door to traditional ENG and box lens workflows while maintaining the image quality expected from a modern digital film camera. It has been purpose built for live production environments where long zoom ranges, parfocal performance and familiar broadcast ergonomics are essential.
The mount integrates precision optical elements that are carefully matched to the URSA Cine RGBW sensor architecture. These optics correct for spherical aberration and ensure accurate focus and sharpness across the image, even when using lenses originally designed for smaller broadcast sensors. This optical compensation allows operators to achieve clean, detailed images while retaining the characteristic handling and responsiveness of professional B4 lenses.
Mechanical construction is designed for reliability in demanding studio and OB conditions. The mounting interface provides a solid, secure connection that supports heavier broadcast lenses and large box lens assemblies. This stability is especially important during live events, sports and studio productions where smooth zooms, repeatable focus pulls and consistent alignment are critical to on air results.
When combined with URSA Cine cameras configured for live production, the mount supports workflows that closely resemble traditional broadcast systems. Operators can take advantage of familiar lens control characteristics while benefiting from the extended dynamic range, color science and high frame rate capabilities of the URSA Cine platform. This makes it possible to deploy a single camera system across both cinematic and broadcast applications without compromise.
The design philosophy behind this mount focuses on integration rather than adaptation. It is part of a wider ecosystem of interchangeable mounts for the URSA Cine range, allowing rapid reconfiguration between PL, LPL, EF and B4 lenses depending on the requirements of each production. This flexibility makes it particularly attractive for rental houses and production companies that need to support a broad range of shooting styles with minimal downtime.

Student Review
This book is an excellent introduction to the basic principles of insurance. We used this text as a supplement in our Intro to Act. Sci. class. It is very readable, easy to understand. Minimal mathematics required, some basic calculus concepts used, but only briefly. Don't let it's small size fool ya, it has plenty of information in there.

A #MustRead for cybersecurity practitioners
Format: Kindle
Rick Howard's latest book is the ultimate reference for cybersecurity practitioners, making it an essential read for anyone in the field. With his straightforward and refreshingly irreverent writing style, coupled with his profound technical knowledge, Rick has created a narrative that is easy to understand and grasp. He delves into the foundational aspect of cybersecurity, which he refers to as the cybersecurity first principle, which he then it to specific high-impact strategies.
The book has eight well-written chapters providing a comprehensive overview of those strategies. Importantly, Rick then offers an up-to-date and thorough exploration of the complementary capabilities (tactical-level tools) that can be utilized to "reduce the probability of material impact due to a cyber event" - the cyber first principle.
In the concluding chapter, Rick succinctly summarizes his contribution to the field, stating, "And that's it. Those are all the tools you need to design, build, and enhance a cybersecurity program based on first principle thinking." This assertion highlights the value of his book as a practical guide for designing and improving cybersecurity programs with a focus on first principles.

Absolute must read if you oversee any portion of a cyber security program!
Format: Paperback
I loved this book. The concepts and ideas presented are a great wake up call for an industry that is so focused on blinking light hardware and the next big technological thing...this book challenges the paradigm that you need to strip your security culture down to some very core ideas...then build a solid security program around your security first principle(s). Without that core idea, you're just throwing away money on tools that may not actually be addressing your root needs.
Great read for anyone looking to rethink their security program, security culture, and security spend.
BRAVO!

Context, Strategies and Wisdom in a single package
Format: Kindle
This was my first book I have read by this particular author. I had spent some time looking for a comphrensive approach to Cyber Security and found many other texts to be lacking. Certain aspects are well documented, but no single source that brought it all together. This is exactly what First Principles brings to the table. As a practicioner that looks for better ways to formulate the objectives of SecOps Use Cases I have found the methods presented in this book to be immensely helpful. I have also given copies aways as a gifts to students who are just entering the field as this is by far the best intro to the long history of Cyber Security that combines the best direction for the future. The historical context that the author brings through first hand experience is beyond a treasure trove. It has been said many times in cheezy ads, but honestly, if you only read one book on Cyber Security make it this one.
