Blackmagic URSA Mini 4.6K Quick Start
EF Mount URSA Mini 4.6K
Blackmagic Design’s URSA Mini 4.6K camera is lightweight,
compact, easy to use and aordable. e Super35 (25.34 x 14.25
mm) CMOS sensor delivers beautiful images that can be recorded
internally onto inexpensive CFast 2.0 Cards—from HD through
4.6K CinemaDNG RAW or UHD ProRes.
ere are two models: EF or PL mount. You’ll want the EF model
if you work with Canon EF, Sigma EF or ZEISS ZE lenses and like
lens data readout in the viewnder as well as auto exposure and
auto focus on some models.
FDTimes usually wriggles out of price discussions—but this is a
camera system clearly intended for independents where cost is an
important concern. So here goes.
e camera body is around $4,995. It’s a complete camera/
production/post-production package in a box—with the full
DaVinci Resolve Studio soware and USB dongle inside.
ere are three essential accessories that you will want as constant companions. Blackmagic Design’s URSA Viewnder is a really good deal and a steal at $1,495. e optics have an indexed
diopter and the 1920x1080 OLED display is crisp enough to actually determine focus clearly. e eyepiece rotates and adjusts
to many viewing angles. It positions in and out from the camera
body which is helpful for both le and right-eyed operators.
Unless you plan on leaving the camera attached to a tripod or
drone, Blackmagic’s URSA Mini Shoulder Kit ($395) is another
essential accessory. It has an ergonomic, adjustable shoulder pad,
rosettes on both sides, a handgrip extension, and a top handle.

URSA Mini 4.6K Camera Quick Specs
For a few dollars more ($895), you should add a Blackmagic
Video Assist 4K 7-inch HDMI/6G-SDI Recorder/Monitor. It can
trigger-record every take. In other words, whenever the camera
starts or stops recording internally, the Video Assist 4K will automatically record a ProRes or DNx copy onto SD cards, via SDI or
HDMI, up to 3840x2160 30p.
Although the Backmagic URSA Mini 4.6K is one of the most intuitive cameras available, and passes the 10-minute rule for being able to gure it out without an instruction manual, here are
a few pages of quick-start notes to reduce the learning curve to 5
minutes.
