Panasonic Lumix G3 - In the RAW test

It has a handy, 115 x 84 x 47 mm compact aluminum housing and costs around 500 euros. This makes it only slightly larger and significantly less expensive than the PEN, although it accommodates 480000 RGB pixels, 100% image coverage, and 0.7x effective magnification in contrast to the one integrated electronic viewfinder. The rotating and swiveling, touch-sensitive 3-inch monitor provides a decent preview with 153 333 RGB pixels.

In addition, it reacts reliably and quickly to inputs, so that it actually benefits the operating comfort - especially since the G3 can also have the usual buttons and rotary wheels. Videos can be recorded with 1920 x 1080 pixels, 50 half images / s including stereo sound in AVCHD format (optional Motion JPEG). For automatic focusing, the G3 uses a contrast measurement on the image sensor and takes 23 points. In good light conditions (1000 Lux), it needed 0.32 in the test, 0.42 s average in darker 30 lux for arming and tripping.


Image Quality The high RAW resolution is striking. At the Panasonic, the detour via the RAW format and Lightroom above all a huge plus: a considerably higher resolution up to 2195 LP / BH. For comparison: With JPEG it is a maximum of 1590 LP / BH. The results of the Dead-Leaves measurements, which describe the appearance of coarse and uneven structures, are better in JPEG mode due to the stronger internal signal processing, but the G3 also needs to be up to 941 LP / BH in the RAW test not hide. The G3 with RAW still can push the G3 with a weak texture loss (through kurtosis 0.2). The downside: a comparatively strong visual noise (0.7 to 3.5 VN). However, the JPEG mode up to ISO 1600 provides almost the same VN values ​​and takes more effect only with ISO 3200 and 6400. In addition, the dynamics are reduced to as low as 8.0 as of ISO 400.

Conclusion: The Panasonic Lumix G3 is a mirrorless system camera more compact than SLRs and has in contrast to the Olympus PEN E-P3 a high-resolution, electronic viewfinder integrated. In the RAW test, it also achieves a very high resolution with which it can compete with the 24-megapixel SLR Alpha 65. At the same time, it keeps the texture loss low.
