Blackmagic Design URSA Mini Pro EF Mount

The Blackmagic Design URSA Mini Pro EF Mount is a precision-engineered lens mount that allows you to use high-quality Canon EF-mount photographic and cinema lenses on your URSA Mini Pro. While the URSA Mini Pro 4.6K G2 typically ships with this mount pre-installed, this standalone kit serves as a replacement or an upgrade for users of the URSA Mini Pro 12K (which ships with a PL mount).

 

In 2026, the EF mount remains the most popular choice for independent filmmakers and content creators due to the massive availability of affordable, high-performance glass from Canon, Sigma, Tamron, and Zeiss.

Core Functionality

  • Active Electronic Connection: The mount features integrated electronic contact pins that facilitate communication between the camera and the lens. This enables:

     

    • Electronic Iris Control: Adjust your aperture directly via the camera’s touchscreen, physical dials, or remotely via an ATEM switcher.

       

    • Lens Metadata: Automatically records lens information (focal length, aperture, and brand) directly into the Blackmagic RAW or ProRes metadata for use in post-production.

    • Image Stabilization: Powers and supports the internal "Image Stabilization" (IS) found in many EF lenses.

    • Push Autofocus: Supports the camera's "Focus" button to trigger auto-focus on compatible electronic lenses.

       

  • Precision Shimming: The kit includes a comprehensive Shim Set, allowing you to fine-tune the flange focal distance. This ensures that the distance scales on your lenses are accurate and that zoom lenses remain "parfocal" (staying in focus while zooming).

     

Key Features

  • User-Interchangeable: Designed to be swapped in minutes. It is secured by four high-strength screws on the front of the URSA Mini Pro chassis, requiring no specialized technician for installation.

     

  • Robust Build Quality: Constructed from chrome-plated stainless steel, the mount is built to withstand the torque and weight of heavy L-series telephoto or cinema-modified EF lenses.

  • Light Baffle: Includes a specialized internal baffle that prevents light scatter and reflections within the mount, ensuring maximum image contrast and reducing flare.

What’s Included in the Box?

  • 1 x Blackmagic URSA Mini Pro EF Mount

  • 1 x Shim Set (various thicknesses for precise calibration)

     

  • 1 x Baffle Tool (for safe installation of the light baffle)

  • 1 x Set of Spare Mounting Screws

     

  • 1 x Moulded Mount Case (for safe storage of your spare PL or F mount)

     

  • Printed Instructions

Operational Insight (2026)

In 2026, the EF mount is the "Swiss Army Knife" for the URSA line. It is particularly valued by users of the URSA Mini Pro 12K who want to utilize the resolving power of high-end EF prime lenses without the extreme cost of PL cinema glass.

Pro Tip: If you notice that your lens focus marks don't match the actual focus (especially on wide-angle lenses), take the time to use the included Shim Set. Adding or removing even a single thin shim can drastically improve the sharpness and accuracy of your lens's focus throw.

A Reliable Office Essential That Keeps Our Body Shop Running Smoothly
Size: 10 Reams | 5000 Sheets, Style: Letter (8.5x11)
In a busy auto body shop, we print a lot of paperwork every single day. Between repair estimates, insurance documents, invoices, work orders, and customer paperwork, having a dependable supply of printer paper is a necessity. Amazon Basics Multipurpose Copy Printer Paper has become one of those products that we always make sure to keep in stock. The quality has been excellent for our everyday office needs. It feeds through our printers smoothly, produces clean, sharp documents, and we haven't experienced the jams or inconsistent performance that can sometimes come with lower-quality paper. Whether we're printing simple forms or detailed estimates, it gets the job done. Another reason we continue to purchase it is the value. Running a business means paying attention to operating costs, and this paper offers a great balance between affordability and quality. We go through a large volume of paper, so being able to save money without sacrificing performance is a huge advantage. I also appreciate the convenience of ordering it through Amazon. Instead of making extra trips to the office supply store, we can have it delivered directly to the shop and know that we'll always have enough on hand when we need it. Overall, this has become our go-to copy paper for our business. It's dependable, high quality, and priced competitively. For any busy office, repair shop, or business that prints a large amount of paperwork, I think this is an excellent choice. We will definitely continue to purchase it and keep it stocked in our office.

Great paper good price
Size: 3 Reams | 1500 Sheets, Style: Letter (8.5x11)
This is a solid everyday paper option that does exactly what it’s supposed to do. The packaging was good—everything arrived in perfect condition with no bent corners or damaged reams. It’s nice not having to deal with warped paper right out of the box. Printing quality has been consistent. I’ve used it for both home and work printing, and it feeds smoothly through the printer without jams. The brightness is good too—text comes out clear and sharp, and colors look decent for standard copy paper. Overall, it’s reliable, good quality paper at a fair price. I’d definitely buy it again.

Nice daily use paper for ink jet printers. A good white rating too. OK for occasional color
Size: 1 Ream | 500 Sheets, Style: Letter (8.5x11)
Very good paper for daily use on ink jet printers. Good price, fast deliver, and packaged well. It even works well for color printing but not what you want for high quality glossy color prints.

Reliable everyday printer paper, no jams and clean prints
Size: 1 Ream | 500 Sheets, Style: Letter (8.5x11)
Standard printer paper that just works. Feeds consistently without jamming across multiple printers I use it in. The brightness level is good and text prints crisp and clear. The 500 sheet ream is a reasonable size to keep on hand. Nothing fancy to say here, it is just reliable paper at a fair price. Amazon Basics has been consistently good for these kinds of commodity items.
