The Panasonic Lumix DMC-GH1 is a digital mirrorless interchangeable lens camera adhering to the Micro Four Thirds (M43) system standard. It was Panasonic's second M43 camera and the first photo/ video model. It slotted above the earlier G1 as the company's flagship model in their M43 line. It is commonly referred to as simply the GH1.
Rollout[edit | edit source]
The GH1 was announced on March 3, 2009, at the annual convention of the Photo Marketing Association (PMA) in Las Vegas, Nevada. It was available to consumers by July 2009 in a kit with a new 14–140mm superzoom lens at a of US$1,500. It was offered in a choice of three body colors: black (designated with a part number suffixed with "-K"), red ("-R") and gold ("-N"). Starting in early 2010, a body-only package was offered at a price of US$700.
The primary difference between the GH1 and the earlier G1 is that the GH1 supports video recording. In fact, the GH1 is designed to capture and is positioned as a camera that is equally capable of recording video or capturing still images.
Features[edit | edit source]
The GH1 is more than simply a G1 that can capture video. Among its other distinguishing features are a multi-aspect image sensor, full AVCHD HD video capability including manual controls over many video functions and stereo sound recording, a highly capable and a sophisticated system including new Face Recognition capability.
Multi-aspect image sensor[edit | edit source]
Panasonic pioneered the concept of an image sensor that was optimized for more than just a single aspect ratio in its high-end compact camera from 2008, the DMC-LX3 which used a much smaller 1/1.63" sensor. The GH1 builds on the multi-aspect sensor concept but with a much larger Four Thirds sensor.
The GH1's 14.0 sensor covers a slightly larger image circle than the Micro Four Thirds design specifies. With a typical sensor the 4:3 image is simply cropped on the top and bottom to achieve 3:2 or 16:9 aspect ratios, but the multi-aspect sensor supports all three sizes at the maximum resolution possible (1:1 aspect ratio is also supported, but that is cropped from 4:3). This also means that the is the same for each image shape. The downside of this approach is that the full potential capability of the sensor in terms of resolution is never realized, so the 14MP sensor only delivers 12MP images.
True HD video recording[edit | edit source]
The GH1 was designed from the ground up to be capable of recording in at 24 frames per second (fps) or at 60fps with stereo sound in the format. A dedicated button on the back panel allows quick access to video start/stop functionality.
When using the Panasonic 14–140mm superzoom lens which was introduced along with the GH1 and included as a kit lens, the GH1 supports (CAF) and automatic (AE) as well as optical image stabilization during video capture. The user is also able to specify and as well as use during video capture for more creative control.. A pair of on-board microphones allow the GH1 to capture stereo sound, with a built-in wind blocking feature; an external microphone can also be attached to allow more control over mic placement and fidelity. Video can be captured in either AVCHD or formats. The GH1 was the first consumer-priced interchangeable lens camera to offer such capabilities. These specs garnered the attention of amateur and even professional filmmakers.
In the United States, maximum video recording length is limited only by the capacity of the memory card used or by battery life, unless using the included AC power adapter. Individual file sizes are limited to 4GB due to restrictions in the SD format, but video will be captured seamlessly between files. However, to avoid a higher tariff rate on devices classified by the European Union as "video camera recorders" GH1s sold in that market are limited to a maximum length of 29 minutes and 59 seconds for a single recording.
Dual-CPU processor[edit | edit source]
The GH1 uses the same Venus Engine HD as the G1, but the requirements of video capture and processing push the limits of the dual-CPU much further. The power of this advanced electronic brain greatly speeds up HD video processing and offers improved reduction performance. In addition it supports output of a directly from the sensor to either the 3 in (76 mm) or the high resolution electronic viewfinder. Beyond photo and video capture, the processor allows the camera to playback both images and sound either in camera or directly to an external television or monitor via HDMI.
Contrast-detect autofocus with face recognition[edit | edit source]
The GH1's mirrorless design eliminates the dedicated (PDAF) sensor employed by traditional relying instead on a sensor-based system. This system is much more advanced than the typical live view implementations employed by DSLRs of the era to support video capture; while those systems are all but unusable for focusing on moving subjects, with sufficient light the GH1's CDAF implementation rivals the performance of the DSLR's PDAF systems while also supporting video.(p8) However, the CDAF system suffers in low light, delivering worse performance than a typical contemporary PDAF setup on an entry-level DSLR.
Like the G1, the GH1 has a face-detection setting which identifies face-shaped objects in the frame for the purposes of setting the and autofocus point. This system also offers "face tracking" ability which follows a targeted face as it moves around the frame. The GH1 adds an advanced "Face Recognition" system that can recall up to six frequently photographed faces and prioritize these faces for focus whenever multiple faces are detected in the frame. Other focusing options include AF-tracking (which can track objects moving through the frame), 23-point AF (which automatically selects the appropriate focus point from among 23 areas of the image) and single-point AF (which allows the user to select among the 23 available focus points).(p8)
Manual focusing can be aided through the use of a 10x magnification function. This magnified portion may be moved around to any portion of the scene, while the high-resolution EVF is sharp enough for nailing focus. In manual focus mode, touching the lens focus ring will immediately turn on the magnification for manual focusing. The GH1 does not offer any sort of .
LCOS electronic viewfinder[edit | edit source]
The GH1 shares the same liquid crystal on silicon (LCOS) electronic viewfinder (EVF) from the G1. This advanced uses field sequential display technology to wring a 1.4 MP-equivalent performance out of an 800x600 pixel display. It does, however, exhibit some color "tearing" if one moves one's eye too quickly.(p4)
The scene in the EVF reflects the aspect ratio selected by the user and can be overlaid with various information about the image exposure and settings. The user can select the amount of information included in this overlay, or it can be removed completely to allow complete focus on framing the image. Among the information available are settings, optical image stabilization mode (there are three), drive mode (single, burst, bracket, timer), image aspect ratio, (, or both), exposure indicator, , shutter speed, aperture, recording mode, , composition-assistance grid lines and an exposure .(pp4, 8)
The EVF live view mode also allows a preview of the actual exposure in manual mode. The user can adjust shutter speed and aperture in manual mode and see the actual effect on the recorded exposure in the EVF. In addition to the usual depth of field preview, the GH1 allows a unique shutter speed effect preview, giving the user a fairly accurate preview of the finished image blurring when using a slow shutter speed.(p8)
The EVF does have some disadvantages. In extremely low light at the sensor limits, image quality degrades into a grainy, and often lagging image. The quality of the live view image can also suffer when using , since the image sensor and processor must pull double duty in recording the image and also feeding a live view to the EVF; this hampers the GH1s ability to capture fast-moving action such as sports photography. In addition the EVF draws significant energy which will cause the battery to drain more quickly than that of a similar DSLR.
Virtually all the functionality of the EVF is available also on the articulating 3-inch (76 mm) LCD display panel. An eye sensor switches the EVF on and LCD display off when the eye is brought up the EVF.
Successor[edit | edit source]
The GH1 was replaced by the 16MP Panasonic Lumix DMC-GH2 which was announced in September 2010.

Firmware Updates[edit | edit source]
Panasonic releases[edit | edit source]
Panasonic has released the following firmware updates:
PTool[edit | edit source]
Vitaly Kiselev developed a utility to replace or "hack" the stock GH1 firmware. These hacks, called "patches", allow users to remove certain firmware restrictions and change video encoding parameters. Some patches enable faster bit rates and improved video quality on the GH1.
Warning: Using PTool is not for the faint of heart; a careless installation can "brick" the camera, rendering it totally unusable.
