- Good rendering at low ISO
- Easier to handle, thanks to its larger grip
- A very nice 3-inch screen
- A very practical pressure wheel for changing settings
- Very compact when used with a 14-42mm pancake lens
- 16Mpix —the smallest pixels available on a micro-four-thirds sensor!
- A significant loss of image quality under low-light conditions
- Noticeably loud shutter “click”
- ISO range is still quite limited, particularly for low ISO
Taking a closer look at its sensor test results:
- The color depth score is satisfactory at 20.8, meaning a good range of colors for your images;
- The dynamic range score of 10.6 is normal for a micro-4/3 camera, meaning that there’s good contrast amplitude between darker and brighter grayscales;
- The low-light ISO score of 703 is comparable to other micro-4/3 sensors, and DxOMark measurements show that the micro 4/3 sensors are not the best in lowlight conditions.
Panasonic GXI vs Panasonic G3
When comparing the Panasonic GX1 vs the Panasonic G3, another micro-four-thirds camera in the same line, we get the exact same behavior. But, this was to be expected as both cameras are build around the same sensor.
Now let’s take a look at how the GX1 compares to its Sony and Olympus competitors:
We see here that the GX1 has some serious competition. The GX1 scores slightly better for low-light and dynamic range than the Olympus Pen EP3 – and while the differences are slight, they clearly show that the GX1 has one of the best 4/3 sensors currently available.
To conclude, the Panasonic GX1 is an intuitive, easy-to-use hybrid, and a good, compact choice for fans of beautiful photos. Its only real problem is its significant loss of image quality at high ISO.
Panasonic has taken something of a lead in terms of compactness, thanks to its offering of pancake lenses that can make cameras like the GX1 truly portable. We will be testing the optical quality of these kinds of lenses, in particular the Panasonic LUMIX GX PZ VARIO 14-42mm, the LUMIX GX PZ VARIO 45-175mm and the Panasonic Leica Summilux DG 25mm F1.4, in the foreseeable future.
Finally, what to choose when faced with cameras using current 4/3 sensor technology or cameras using APS-C sensors, especially now that the latter is not particularly more cumbersome than the former? There are still a lot of questions about micro-four-thirds sensor technology, and we expect that a lot more ink will be spilled in lengthy discussions before there are any definitive answers, especially with Canon launching the G1X featuring a sensor slightly larger than a micro-4/3.
