Photographers who also aspire to be cutting edge cinematographers can get the best of both worlds with the new Panasonic Lumix DMC-GH4, which is the world’s first mirrorless, interchangeable lens camera with 4K video capture.
Panasonic just introduced the Lumix GH4 ahead of the big CP+ Camera & Photo Imaging Show 2014 in Japan next week, where it will join several intriguing new cameras. (Yesterday, Pentax announced that its newest 645D medium format camera with a CMOS sensor will also be on display at CP+)
Panasonic first teased the 16-megapixel GH4 at the CES show in Las Vegas last month, showing off a prototype of the 4K-shooting camera under glass. We were able to snap a stealthy photo of the camera during the show.
The new Panasonic Lumix GH4 looks similar to its predecessor, the GH3, which was introduced at photokina 2014 and also used a 16MP sensor.
Under the hood though, the GH4 is a whole new animal, with a newly developed 16.05MP “Digital Live MOS sensor” designed to not only capture 4K video, but reduce the wobbly “rolling shutter” effect you can get when you pan too aggressively with a CMOS-based camera. This is key because rolling shutter can be even more pronounced in ultra-crisp 4K video, which features 4,000 pixels of horizontal resolution, making it approximately four times the resolution of HD video.
We actually predicted this trend of 4K video shooting coming to more digital cameras in our piece “5 Tech Trends That Are Changing the Photo Industry Today” from last year.

This may be the year of the 4K-compatible CompactFlash card, the latest coming from Delkin. The new 1050X UDMA 7 Delkin Cinema card targets videographers, particularly those shooting 4K on DSLRs such as the Canon EOS-1DC and C500. This is Delkin’s fastest card to date, featuring write speeds of up to 120MB/s and read speeds up to 160MB/s.
As Delkin explains, the Canon EOS-1DC, for example, requires UDMA 7 cards with a minimum write speed of 100MB/s in order to record 4K footage at 24 frames per second without dropping frames or stopping recording.
The 1050X is also compatible with digital file recorders such as AJA’s Ki Pro Mini.
Delkin’s CF Cinema cards are available now in three capacities: 32GB, 64GB and 128GB.

Priced at less than $5,000, Sony’s new FDR-AX1 4K Handycam will appeal to indie filmmakers and videographers on a budget who want to move into 4K video without breaking the bank. Built around a BSI 1/2.3-type Exmor R CMOS sensor, the FDR-AX1 can record 4K as well as HD video.
Movies are recorded in the XAVC S format using MPEG-4 AVC/H.264 Long GOP for extended recording time of almost two hours of 4K/60p or 3 hours of full HD when storing footage on a 64GB XQD card. The camcorder features dual, hot-swappable XQD card slots so you can continue to record while replacing a full card.
Equipped with a 20x, image-stabilized G lens, the AX1 has an optical zoom range of 31.5-630mm (35mm-equivalent). The camcorder also features dual XLR connectors and an HDMI out. The latter will be upgradeable to the new HDMI 2.0 standard via a firmware update. Since 4K TVs are expensive and haven’t become as ubiquitous as HDTVs, the AX1 can easily output full HD by changing the camera’s output settings.
Although there are a few 4K cameras that are smaller than the 7 7/16 x 7 19/32 x 14 ¼ inches, 86.1 ounce FDR-AX1 and less expensive (see Greg Scoblete’s roundup of a half-dozen 4K cameras on PDNOnline) but, at first glance, the FDR-AX1 seems to provide entrée to 4K video without too much compromise in terms of pro features and functionality. It’s likely that the competition for prosumer-type 4K video cameras will increase in the coming year. We’ll have to wait and see what happens but our money’s on a very interesting NAB show in April 2014.
The FDR-AX1 ships in October and comes with Vegas Pro 12 Edit software and a 32GB XQD memory card.
