Panasonic Lumix GH5 announced
Panasonic announced the LUMIX GH5 at CES 2017, the latest flagship model of LUMIX G DSLM cameras based on the Micro Four Thirds system standard.
The new camera delivers a high-end, hybrid performance to photo enthusiasts and professional videographers looking to capture moments in 4K 60p/50p video and 6K PHOTO.
The LUMIX GH5 features a new Digital LIVE MOS Sensor increases the pixel count by 25% compared to the GH4, from 16.05 to 20.3 megapixels, while also removing the low-pass filter. The camera also comes with a new image processor Venus Engine, which achieves improvement especially in natural texture expression. The engine’s Multi-pixel Luminance Generation renders clear, sharp images by referring to a 9x larger area of pixel information during the de-mosaic process for precise detail reproduction.
With Intelligent Detail Processing, the characteristic of every pixel is analysed to detect whether the pixel is located at a flat, detail or edge part of the picture. Optimum processing according to the characteristic of each pixel is then applied.
Also, Three Dimensional Color Control detects not only hue and saturation, but also brightness, and applies optimum control according to the value of each factor. The conventional Multi Process NR (Noise Reduction) is upgraded to High Precision Multi Process NR. It boasts 4x the noise identification accuracy compared to the previous engine and preserves details even after the noise reduction process. As a result, photos can be clearly shot even at high sensitivity ISO values of up to 25,600.
The LUMIX GH5 also incorporates the 5-axis Dual I.S. (Image Stabilizer) 23, which suppresses blurring in more powerful and advanced ways for both photo and video recording, including 4K
The LUMIX GH5’s high-precision gyro sensor controls both the O.I.S. and B.I.S. compensation by studying the focal length and shooting conditions, making it possible to use a max. 5-stop slower shutter speed.
With the LUMIX GH5, the signal readout speed has been accelerated by max 1.7x in the new Digital Live MOS Sensor, and the new Venus Engine processes signals at max 1.3x higher speed. This synergy realizes 4K 60p/50p ultra high-definition, smooth, video recording for the first time in a DSLM camera, says Panasonic. It is also capable of internal 4:2:2 / 10-bit video recording, which is the colour subsampling commonly used for film production, for even more faithful colour reproduction5.
Users can freely choose between MOV, MP4, AVCHD Progressive and AVCHD formats at a variety of frame rates, and there is no recording time limit for both FHD and 4K video. Professional users working globally can set the system frequency to 59.94Hz, 50.00Hz or 24.00Hz.
While ‘Cinelike D’ and ‘Cinelike V’, which have similar gamma setting characteristics for film production, are available in Photo Style for video recording, the LUMIX GH5 also provides ‘Like 709’ for compatibility with HDTV. A paid software upgrade to support V-LogL video recording is also available.
In response to requests from professional users, the LUMIX GH5 comes with a Waveform Monitor and Vector Scope. It also embeds SMPTE-compliant Time Code either in Rec Run or Free Run count-up methods, which makes it easy to synchronize multiple video footage or sound sources in the post production workflow. Luminance levels can be selected between 641023 / 64-940 / 0-1023 (10-bit). Synchro Scan mode suppresses flicker and Color Bars (SMPTE / EBU / ARIB Standard) are also available.
The LUMIX GH5 comes with a newly improved Depth from Defocus and Contrast AF technology, which not only calculates the distance to the subject by evaluating two images with different sharpness levels, but also analyses the form, size and even motion of the subject comprehensively. Thanks to the new Venus Engine, the time for measuring the distance to the subject is 6x faster, while factoring the distance into in-plane or in-depth is 2x faster.
The speed of sensor drive during auto focusing in photo shooting mode has been increased to 480 fps, which is 2x faster than that of the GH4. Consequently, the LUMIX GH5 realises ultrahigh-speed AF of approximately 0.05 sec7 and 12 (AFS) / 9 (AFC) fps high-speed burst shooting using a mechanical shutter in full resolution.
For even more precise focusing, the number of focus areas has been increased from 49 to 225. Users can create a group of focus areas depending on the composition and can control it easily with a new joystick located on the thumb position, without taking your eyes off the subject. This is possible even when using the LVF or releasing the finger off the shutter button.
If focus is not exactly as the user intended when the shutter is pressed, the LUMIX GH5’s Post Focus function enables users to select the specific focus point even after shooting – particularly helpful in situations like macro shooting where severe focusing is required. In addition, the camera also features a Focus Stacking function. Taking a single macro photo with specific areas in focus can sometimes be difficult, Focus Stacking enables users to take multiple images of the same frame with different focus points. You can then combine them into one image with the defocus as you like.
The LUMIX GH5’s new 6K PHOTO function makes it possible to capture moments at 30 fps by extracting the frame with the best timing out of the 6K burst file (in 3:2 or 4:3 aspect) to save as an approximately 18-megapixel equivalent high resolution photo. 4K PHOTO has also been upgraded enabling 60 fps high speed capture in approximately 8-megapixel equivalent resolution. In 6K/4K PHOTO, three exclusive modes are available to choose from depending on the situation; 6K/4K Burst, 6K/4K Burst (Start/Stop) and 6K/4K Pre-burst.
The LUMIX GH5 has a large LVF (Live View Finder) with a magnification ratio of approximately 1.52x / 0.76x (35mm camera equivalent). The high-precision, high-speed OLED display features 3,680K-dot high resolution and 100% field of view. Adopting a static-type touch control system, the 3.2-inch free-angle rear screen in 3:2 aspect with 1,620K-dot high resolution achieves approximately 100% field of view.
The LUMIX GH5 integrates Bluetooth 4.2 and Wi-Fi 5GHz (IEEE 802.11ac) connectivity to offer a more flexible shooting experience and instant image sharing with easy operation. The LUMIX GH5 is compatible with the new Battery Grip DMW-BGGH5. By using two batteries, one in the camera and the other in the grip, the DMW-BGGH5 extends the battery life for longer time shooting. The optionally available microphone adaptor DMW-XLR1 is a plug-in type adaptor for XLR microphone to record high quality stereo sound.
Firmware updates will add: Full HD 4:2:2 10bit video recording capability (scheduled for April 2017); 400Mbps 4:2:2 10bit All-Intra video recording in 4K 30p/25p/24p; Full HD, high resolution video recording in Anamorphic mode; Hybrid Log Gamma in Photo Style mode which enables popular 4K HDR video recording and USB tethering (all scheduled for second half of 2017).
The Lumix GH5 will be available (body only) in late March for $1999.99
