Panasonic Lumix GH4 V-Log L Function Firmware Upgrade Kit DMW-SFU1

PRODUCT HIGHLIGHTS

• Adds V-Log L Gamma to GH4, GH5, FZ2500
• Wide Dynamic Range of up to 12 Stops
• Improved Color Matching with Varicam
• Similar Characteristics to Cineon
• Same LUT and Curve as Standard V-Log

Maximize the dynamic range of the Lumix DMC-GH4, DC-GH5, or DMC-FZ2500 with this V-Log L Function Activation Code from Panasonic. This code, which is delivered on a physical card, allows you to easily install the V-Log L gamma onto the camera, giving you a flat profile that provides a wide dynamic range of up to 12 stops, improving upon the range previously attainable with the GH4, GH5, or FZ2500. The addition of this gamma also allows users to better match color with existing Varicam systems that feature standard V-Log, as both profiles utilize the same characteristic curve and LUT. Additionally, the profile has been developed to have similar characteristics of Cineon, which is used for film digitization.

Updating your camera is a stepped process similar to updating your firmware; although, you will need this activation code along with your camera's serial code to generate an upgrade key from Panasonic's Update Portal. This upgrade code is also region specific and is designed to work with cameras distributed in Australasia.
