Blackmagic Pocket Cinema 4K

4K- DCI capable DSLM camera from Blackmagic.

Introduction

About five years ago, Blackmagic introduced one of its first cameras, the Pocket Cinema Camera. The successor, the Pocket Cinema 4K, is available with an updated design, a larger case and a Four Thirds Sensor.

Design

The design of the Pocket Camera 4k is even more in line with a Production Camera than its predecessor Pocket Cinema. The case is comparatively large even for the DSLM sector. Thanks to the rubber coating, however, even people with small hands can hold the camera firmly.

The Pocket Cinema 4k barely fits on a gimbal, as it is noticeably wider than most DSLRs. Although the case is made of plastic, it’s solidly built. The quality of the buttons meanwhile are good for this price range. The touch screen measures 5 inches, is seamlessly integrated and offers a very good image display. The problem, however, is that it can’t be either swiveled or unfolded. This problem become more acute with the relatively small viewing angle of the display. However, on a positive, the menu can be operated from the display and is clearly set out.

The Pocket Cinema 4k features four built in microphones, built in recorders and external buttons and dials that provide fast access to the most important functions. That means users can quickly check framing and focus, capture audio and record files without having to carry around extra monitors, microphones, recorders and cables.

Connectivity wise the Pocket Cinema 4k offers HDMI, headphones, 3.5mm jack, USB-C and mini XLR with phantom power plus bluetooth control.

Usability

The Blackmagic Pocket Cinema Camera 4K uses the same MFT (micro four thirds) lens mount as the original Pocket Cinema Camera. The MFT lens mount was designed specifically for smaller camera bodies with shorter flange focal distance. The MFT mount allows for different lens adapters. You can get adapters for PL, C, EF and more, so lenses can be used from a range of manufacturers.


The Pocket Cinema 4K offers ProRes and Raw formats. Also Blackmagic RAW is now available for the Pocket Cinema 4K. Recordings can be made in 4K DCI, UHD (up to 60 FPS) and FullHD (up to 120 FPS). However, in FullHD and 120 frames per second, the sensor works in "window mode", which only uses a 2/3 inch area of the sensor. Although this reduces the photosensitivity and the angle of view, it allows users to record slow-motion images in 12-bit raw or 10-bit ProRes formats.

The Pocket Cinema 4k offers 13 f-stops of contrast range. The Pocket Cinema 4K is now also equipped with the dual-base ISO. Therefore, you can choose between native ISO400 and ISO3200. With ISO1250 the mode changes automatically. That means that users experience similar noise with ISO1000 as with ISO6400. Compared to the Ursa Mini Pro, where you can see significant noise from about ISO1600, the Pocket Cinema 4K can also achieve good results with ISO3200 or ISO6400.

CFast-2.0 or SD cards can be used as recording media. At very high data rates, only the CFast 2.0 standard is fast enough. ProRes LT with approximately 365 Mbit per second at DCI-4K-25p and with 85 Mbit per second at HD is the smallest recording format that the camera offers, except proxy.
The fact that the "smallest" available codec still works with 365 Mbit / s (4K) or 85 Mbit / s (FHD) potentially could make is suitable for long documentary shoots but, as a result, storage space requirements and copy times are higher than with lower data rate codecs.

Sound recording is possible via the Mini-XLR inputs for connecting professional microphones such as lapel mics and booms. There are also built in microphones and as a third option there’s a 3.5mm stereo audio jack so users can utilise different types of video camera microphones.

The weight without optics is 0,8kg / 1,8 lbs.
