Firmware Update 2.2 for GH4 mirrorless camera will make it easier to use anamorphic lenses with the camera. The new anamorphic mode allows the camera to capture video from a 4:3 aspect ratio chunk from the middle of the sensor to match the projection of specialist lenses, allowing genuine anamorphic capture, rather than digital simulation of the look.
Panasonic GH4 Firmware Update 2.2 Details
Thanks in part to its Micro Four Thirds format and 4K recording ability, firmware Ver.2.2 for the LUMIX GH4 enables an Anamorphic (4:3) Mode capable of recording video in 3328 x 2496 pixel (equivalent to approx. 8.3-megapixel) resolution at a frame rate of either 23.98, 24, 25 or 29.97 fps. With an anamorphic lens such as 2x*1 you can capture and un-squeeze a 3356×2496 image in post-production. In addition, 4:2:2 / 10 bit HDMI output is also available*2.
A further enhancement of the new firmware is the addition of a very high shutter speed of 1/16,000 sec. when using its electronic shutter mode.
*1 To convert the footage to a cinemascope aspect for playback, corresponding software and device(s) are required.
*2 If you use the HDMI output when [Bit Mode] in [HDMI Rec Output] is set to [4:2:2 10bit], black bars appear on the right and left side of the image. As a result, the image will appear on the screen in a smaller size (2880×2160). In addition, you cannot record motion picture while using the HDMI output.
