About This CameraThe Panasonic Lumix DMC G1 arrived in 2008 as a mirrorless camera built around the Micro Four Thirds format. Its 360 g weight and compact 124 x 84 x 45 mm body make it easy to carry. That combination suits everyday, travel and learning photography. An electronic viewfinder and a flip-out LCD make framing comfortable at eye level or from awkward angles, and the Micro 4/3 mount accepts interchangeable lenses. Owning one today means accepting its era. Video is limited to Standard HD, there is no wireless connectivity, and the battery is rated at 380 shots per charge, so a spare is worth considering for longer outings. | |

About the OpticsA 12.1 megapixel CMOS sensor in the Micro Four Thirds format sits at the heart of the G1, paired with the Venus Engine HD II processor. That resolution suits everyday prints and web sharing, though heavy cropping is more limited. The ISO range runs from 100 to 3200, covering bright daylight through to dim interiors. The maximum shutter speed is 1/4000s. Autofocus offers 23 focus points, and the electronic viewfinder displays the scene as you work. The maximum burst rate of 3 fps is modest, so the camera suits deliberate, posed or static subjects better than rapid action sequences. There is no in-body stabilisation to steady handheld shooting, so sharper results in low light depend on steady technique, faster shutter speeds or a stabilised lens. A tripod or other support also remains an option. | |
Megapixels ⓘThe higher the number of megapixels, the more detail the cameras sensor can capture. | 12.1 MP050 |
Image resolution ⓘImage resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution. | 4000 x 3000 |
Sensor type ⓘThe camera sensor captures light and records the image. Sensors vary in physical size, the number of pixels, and quality. | CMOS |
Sensor size ⓘThe sensor size contributes to the overall quality as well as the dynamic and tonal range a camera can capture. As a rule of thumb, the more surface there is to read the light, the more information it will capture. | 13 x 17.3 |
Sensor format ⓘRefers to the most commonly used sensor sizes. | |
Continuous shooting ⓘThe number of sequential frames per second the camera can write to the memory card when shooting in burst or continuous mode. | 3 fps045 |
Lens mount ⓘThe lens mount will tell you what type of lens range you can fit onto the camera body. Often the same camera company will have different lens ranges for different cameras. | Micro 4/3 |
Image processor ⓘThe image processor in the camera converts the information collected on the sensor for digital storage on the memory card. | Venus Engine HD II |
Aspect ratio ⓘThe aspect ratio refers to the proportional difference between width and height. The most popular aspect ratios are 3:2 and 4:3. | |
Min ISO ⓘRefers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image. | 10030200 |
Max ISO ⓘRefers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise. | 32003003280000 |
Min ISO (expanded) ⓘExpanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 10030200 |
Max ISO (expanded) ⓘExpanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 32003003280000 |
Minimum shutter speed ⓘThe minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory. | 6044080 |
Max shutter speed ⓘThe maximum shutter speed tells you the length inside 1 second the camera will capture. These can sometimes be extended with accessories such as extra external batteries. | 400080032000 |
Autofocus points ⓘAutofocus points show where the camera is focusing graphically as squares or brackets in Live View or on an electronic viewfinder. These points are also used for light meter readings. | 230300 |
In-body stabilisation ⓘIn-body Stabilization means the camera has a certain technology embedded that counteracts camera shake. | No |
Viewfinder type ⓘThe viewfinder type is either electronic or optical. Electronic viewfinders will have a small screen in the viewfinder. Optical viewfinders will use prisms and mirrors to look through the lens. | Electronic |

Video34/100 | |
About the VideoThe video specification shows the camera's era. Recording tops out at Standard HD resolution, and the maximum frame rate is 30 fps, enough for casual clips and documentation. That earns a video score of 34 out of 100, a limited result, and the G1 sits in the bottom 5% of our database for video. Footage saves as Motion JPEG files, so plan card space for longer recording sessions. There is no built-in intervalometer, so timelapse sequences need another approach, such as shooting stills and assembling them later. Treat the G1 as a stills camera that can also grab the occasional short clip. The limited video score follows from the resolution and frame-rate limits and the absence of a built-in intervalometer. | |
Video ⓘIndicates if this camera is capable of recording video. | |
Max video resolution ⓘThe best resolution this camera can capture video in. Modern cameras can capture up to 8K video. | |
Max video format ⓘVideo resolution measured by the greatest number of pixels possible in each frame, width by height. A higher resolution means more detail or clarity in your video. | 1280 x 720 |
Max video frame rate ⓘHow many frames per second your video will capture. Most cameras have options for multiple frame rates, depending on the resolution you shoot in. For a general video, 24p or 30p is the standard, but more serious filmmakers may need a higher frame rate for creative effect. | 30 fps |
Timelapse built in ⓘA built in time-lapse mode will allow continuous shooting throughout a prolonged period of time to be compressed into a sped up video. | No |
Video file format ⓘDifferent cameras can record in various video file formats. The File format you record in can impact how you edit and use the files. | Motion JPEG |
Features36/100 | |
About the FeaturesHandling centres on a 3-inch LCD that flips out from the body, which makes waist-level and overhead framing straightforward. The screen is not a touchscreen, so settings are adjusted through physical controls instead. Live view and the electronic viewfinder work together: you can check composition on the rear screen or bring the camera to your eye. With 202,000 dots in the finder and 460,000 on the LCD, the displays are serviceable rather than especially sharp. Flash is well covered for a compact body. A built-in unit handles quick indoor shots, and an external flash can be fitted when you need more power. The features score of 36 out of 100 is limited, largely because the touchscreen, weather sealing and Bluetooth are missing. Rain and dust call for care, since the body lacks weather sealing. GPS is absent as well. | |
Builtin flash ⓘA built-in flash will often be positioned right above the lens. This will automatically pop up when you activate it. | |
External flash ⓘExternal flashes are often connected through a hot shoe at the top of a camera, or a cable at the side of the camera. | |
GPS ⓘGPS features in a camera will include location metadata to each of your photographs. | No |
Weather sealing ⓘWeather sealing capabilities will give you more confidence when shooting in unfavourable conditions. | No |
| Screen type | LCD |
Touch screen ⓘTouchscreen allows you to change camera settings and access menus with a swipe of your finger, instead of using buttons. | No |
| Screen size | 3" |
Screen dots ⓘScreen dots indicate the resolution of the LCD screen by including each sub pixel. | 4600001150001500000 |
Flip screen ⓘA flip screen (or articulating screen) is a second screen which can flip out from the side or top of the camera. This rotating screen allows you more freedom to take photos at different angles. | |
Live view ⓘLive View feature allows you to see a continuous live video of what is being seen through your lens. | |
Wi-Fi ⓘBuilt-in Wi-Fi allows you to connect your camera and share images wirelessly. | No |
Bluetooth ⓘBluetooth capabilities allow you wireless control of your camera with other external devices. | No |
Storage & Battery21/100 | |
About the Storage & BatteryStorage runs through a single slot that takes SD, SDHC or MMC cards. SDHC support means larger-capacity cards work, but with only one slot you will want spares on hand and a habit of downloading before the card fills. The DMW-BLB13 battery is rated at 380 shots per charge, a modest figure that rewards planning for heavier use. The storage and battery score of 21 out of 100 is limited, reflecting that battery rating and the single card slot. There is no USB charging, so the battery cannot be topped up from a laptop or power bank over a USB cable. A spare battery is a sensible purchase for longer shooting days. | |
