Panasonic has released a firmware update for the Lumix GX7. Firmware version 1.3 provides the following improvements:
- Connection problem with Apple iOS devices via Wi-Fi is fixed.
- Improved stability of startup process in the use of UHS-I compliant SD memory card.
You can download the update here on Panasonic’s website.
To go along with the new Panasonic GH4 4K camera that will be announced later tonight / early tomorrow, Kingston is first out of the gate with its official announcement of a new SDHC/SDXC UHS-I Speed Class 3 card in 16GB, 32GB and 64GB capacities. The new Speed Class 3 card guarantees minimun write speeds of 30MB/s.
The minimum write speed of these cards translates to roughly 240Mbps, which fits well within the max on-board data rate of the Panasonic GH4’s 4K capture at 100Mbps for its IPB .mov/.mp4 4K capture and 200Mbps for its ALL-Intra .mov and .mp4 HD capture. Additionally, the new Kingston card provides max speeds of 90MB/s read and 80MB/s write.
Pricing isn’t all that bad either, considering the performance they offer. The 16GB cards run around $40 street and the 64GB cards are around $105 street. Check them out here on Amazon.com.
Class 10 cards deliver on speed for HD video capture, which goes along with the size advantage of the SDHC spec. For more details on what all the classes and card specs mean, check out my resource article Demystifying SD Cards.
The Class 10 rating is a rating intended for evaluating video capture performance. In this case, Class 10 is the fastest rating currently available for video performance, which means these will work with just about every HD video camera on the market today.
