How To Setup and Configure the Brevis 35mm Adapter

The advent of affordable 35mm Lens Adapter systems have brought a new level of creative control to digital filmmakers. With that comes a new level of complexity…lens adapters can be confusing and sometimes downright difficult to configure with your camera. The crew here at FreshDV tends to be visual learners, so we thought we’d help shed a little light on the subject with a 35mm adapter video tutorial series. To that end, here is an 11 minute video that covers the basic setup and configuration of a Cinevate Brevis 35mm Adapter.

Video Tutorial: Understanding Depth of Field

Depth-of-Field. In simple terms DOF can be defined as “the distance in front of and beyond the subject that appears to be in focus.” Seems simple, right? But the myriad factors that contribute to a composition’s Depth of Field are often misunderstood (and frequently overly-simplified), leaving many filmmakers and photographers with a false understanding of the physics at play. And it goes without saying that when you educate yourself on the factors that contribute to DOF, you gain a greater level of control over your images, whether you are a cinematographer or photographer, professional or novice. A grasp of the basics of DOF become even more essential when shooting with a 35mm lens adapter system for video cameras.

That is why I am pleased to present the following 20 minute primer on the subject of Depth of Field, filled with practical illustrations and explanations of the physics at work in a lens, and simple examples that will help elevate your understanding of the subject. It thoroughly covers the topics of aperture size, focal length, camera-to-subject distance, circle of confusion (CoC), hyperfocal distance, and infinity focus. I believe that you’ll find it a very informative and approachable explanation of a somewhat arcane and confusing topic.
