A Look At The World Of 4K Recording

Since introducing the GH4, Panasonic has become the newest competitor in the Ultra HD scene. With AV enthusiasts increasingly turning towards 4K, we’re taking a look at some of the current players in 4K recording.

Red Epic Dragon

RED is one of the best known brands in the Ultra HD world, and has a reputation as a leading innovator in cinema technology. The newest member of their line up is Red Epic Dragon. Their latest sensor boasts 16.5 stops of dynamic range in addition to its size and resolution. The amount of noise, which has been the chief complaint about the RED line of cameras by cinematographers in the past, has been vastly improved even at 6K RAW. Epic Dragon, of course, comes with all the advantages of other RED cameras such as RED workflow, RED codec, and compatibility with both EF and PL mount lenses, which gives you maximum lens choices.

Sony CineAlta F65

Ever since its entrance into the Ultra HD world with PMW­F55, Sony has quickly become RED’s major competitor in the field. The latest in their CineAlta line up is F65 which offers recording up to 8K resolution. Like the RED camera, Sony users can take advantage of Sony’s own 4K workflow. It uses CMOS sensor and has a rotary shutter option to overcome the defects of rolling shutter. The sensor also employs an S­Gamut system which provides wider colour space than a print film to achieve the most natural colour.

GoPro Hero3+ Black Edition

GoPro has also dipped into the UltraHD pool with their latest camera Hero3+ Black Edition.

Panasonic Lumix GH4

Mirrorless camera has been gaining more and more attention as the (often times better) alternative to the DSLR amongst digital photography enthusiasts in the recent years. Panasonic is still holding out on the exact release information, but it is expected to come out this winter. It would be interesting to see if DSLR filmmakers are making the switch to mirrorless with the introduction of 4K video recording which can be a real game changer. Mirrorless cameras are very similar to DSLR in terms of their operation, but without the annoyance of a mirror mechanism. It also may attract a lot of young filmmakers who are less bound by the lens choice and looking to purchase their first professional camera.

Quick Spec Overview:

• Sensor/Effective Resolution: 17.3 x 13.0 mm(17.20 megapixels)/16.05 megapixels
