That was fast: Blackmagic Design drops price of Production Camera 4K to $2,995

Just three days after the formal announcement of Panasonic's 4K GH4, and before Panasonic has announced pricing or availability for its new camera, Blackmagic Design has cut $1,000 off the price of its Production Camera 4K, bringing the price down to $2,995 (U.S.). That should be below the price of the GH4 plus its dock. In addition, as I wrote yesterday, the GH4 will need an external video recorder to take full advantage of the camera's 4K output, while the Production Camera 4K has a built-in SSD dock, which makes Blackmagic's camera an even better deal. The Production Camera 4K also has a Canon EF/Zeiss ZE mount, compared to the GH4's Micro Four Thirds mount, which could be very important if you've already got an investment in Canon lenses.

I suspect that Blackmagic was planning the Production Camera 4K's price drop as a big announcement at NAB in April, but the company decided to make the announcement early after seeing Panasonic's moves. It's pretty amazing--in the space of four days, we've gone from no 4K cameras under $3,000 to two.

Panasonic's GH4 lowers the bar for 4K pricing, but are the compromises worth it?

Panasonic’s flagship GH series of Micro Four-Thirds ILCs has developed a strong reputation as cinematography cameras, starting with the GH2, which had its firmware hacked to enable much higher bit rates than the stock model. The GH3, introduced last year, took many of the capabilities added by third parties and built them into the base camera. Last month, at the Consumer Electronics Show, Panasonic showed a prototype of a new GH that looked almost identical to the GH3 but supported 4K video. As of this weekend, we’ve learned the specifications for the new camera, called GH4, but not the price or release date.

The GH4 16.05 megapixel CMOS imager doesn’t break any records for still imaging, but it does support 4K video at both standard resolutions: Ultra HD (3840x2160 @ 30p,) the broadcast/video 4K standard and the resolution of consumer Ultra HD displays, and Cinema 4K (4096x2160 @ 24p,) the baseline standard for theatrical production, post-production and exhibition. In 4K mode, it uses IBP compression with I and B frames at 100mbps, while in 2K mode, it supports All-I compression at 200mbps.

The GH4 has an interesting (and confusing) approach to how it handles storage of 4K video: When using an SD card, video is stored in 8-bit 4:2:0, and is output to the HDMI terminal as 8-bit 4:2:2. If you remove the SD card and use an external recorder, the HDMI output is 10-bit 4:2:2. You can also opt for a dock (Panasonic refers to it as an “interface unit”) that provides two XLR audio inputs with LED meters, four SDI outputs (two of which are 3G) and a 12VDC power socket. The SDI outputs can presumably drive an external recorder and monitor simultaneously at 10-bit 4:2:2. The dock won’t win any design awards—it just about doubles the size of the GH4—but it does add the interfaces that professional users need (or are forced to add with third-party hardware.)

Panasonic’s approach to storing 4K video means that an external recorder will be a necessity. In this regard, Blackmagic Design’s Production Camera 4K (the camera most likely to be compared to the GH4) has an advantage, because users can insert a SSD directly into the Blackmagic camera, eliminating the need for an external recorder.

I have to admit that I’m disappointed with how Panasonic chose to implement storage on the GH4. It would have been nice to be able to use the camera in a handheld mode without a lot of additional hardware, but in 4K mode, the SD card is only good for proxy recording in 4K mode. (To be clear, you can store 4K video on the SD card, but if you're serious enough about 4K to put up with all the other issues you'll need to deal with in post-production--massive storage, faster PCs, bigger monitors, etc.--8-bit 4:2:0 won't cut it.)

At CES, Panasonic representatives said that they expect the GH4 to be priced less than $2,000 in the U.S. That price won’t include the dock, which is likely to cost at least $1,000. So, Panasonic could get the GH4 plus dock to market at around $3,000—but I wouldn’t be surprised if the pair launches at closer to $4,000.

Update (March 10, 2014): Panasonic has revealed prices and availability dates for the GH4. The GH4 body's suggested retail price is $1,699.99 (U.S.). The dock (officially called the DMW-YAGH XLR/SDI Interface Unit) is priced at $1,999.99. If you buy both the GH4 and dock as a bundle, it's priced at $3,299.99. I’d love to see a third party develop a more elegant (and cheaper) dock, but there may not be a big enough market for it to make financial sense.

The GH4 is one of the least expensive ways of getting into 4K, if not the least expensive way. However, as we’ve learned from Blackmagic’s cameras, inexpensive means compromises, and the GH4 is no exception. It remains to be seen if the GH4’s compromises are ones that you can live with.
