Panasonic Updates GH5 Firmware, No Autofocus Fix Yet

Panasonic GH5By James DeRuvo (doddleNEWS)

As the first part of multiple firmware updates coming this summer, Panasonic has added a few new features to the GH5, plus a couple of bug fixes. But while they have acknowledged a problem with its autofocus, a fix for it is going to have to wait.

“Panasonic is announcing the new firmware update program Ver.1.1 for DC-GH5 to further enhance its performance. The new firmware Ver.1.1 enables 4:2:2 10-bit video recording in either FHD [MP4(LPCM)] / [MOV] and Anamorphic (4:3) mode, in addition to the existing 4K video recording mode.” – Panasonic Press Release (via DP Review)

gh5vs11Leading the laundry list of improvements to the April 24th ver. 1.1 firmware update is the addition of 4:2:2 10-bit, full HD video capture at 100 MBps with up to 60 frames per second. 10-bit 4:2:2 IPB capture has also been added at 3328 x 2496, and encoded at 150Mbps, leaving those who shoot widescreen and anamorphic with a solid option.

Panasonic also plans a higher resolution anamorphic capture option with 400MBps All-I capture for 4K, and 200Mbps All-I capture for Full HD, which will follow in second update scheduled for later this summer.

Ver. 1.1 also includes a few housekeeping and bug fixes including addressing a problem with the exposure adjustment mode that did not operate properly in live view standby while using Variable Frame Rate under certain conditions. Panasonic is also addressing a problem with so-called “after images,” which can appear when recording video under higher ISOs while using V-LogL.

Outside of that, though, there is no fix yet for the problem that has arisen where the GH5 won’t lock autofocus in standard mode, and tends to hunt for a subject, even in the more stable multi point modes. And you shouldn’t expect it so soon either. Panasonic moved to acknowledge the bug earlier this week in a video released by one of their official Luminaries, offering a workaround.

“We recommend to select the 1-area AF in 30p or 60p frame rate for more comfortable Auto Focus speed,” Luminary Joseph Linaqschke (PhotoJoseph) said in the statement. “When you select 24p, 1-area AF is recommended. If you are still experiencing slower than desired AF, Panasonic suggests to override the AF by pressing the shutter button halfway down.”

PhotoJoseph also assured us in the statement that Panasonic is committed to “further improve the autofocus quality,” so I’m guessing that this issue will be addressed with the second half of this two part firmware update scheduled to come later this summer, or perhaps its own independent firmware update. But the take away is that Panasonic is moving quickly to address the issue and once they have a fix and tested it out, they’ll get it out ASAP.

Granted, it’s not a fast fix with this scheduled update, but the issue may one more complicated. Here’s hoping it isn’t. Meanwhile, this current GH5 update Ver. 1.1 is scheduled to be released on April 24, 2017 at the LUMIX Customer Support website here.
