Pt. 1 - Appearance and Zoom Range
Pt. 2 - JPEG Noise
Pt. 3 - ISO 80 JPEG Crops at 35mm & Full Aperture
Pt. 4 - Flare Performance
Pt. 5 - Noise Performance Revisited
Pt. 6 - G7 Default JPEG vs GX100 Silkypix Conversions
Pt. 7 - Key Timings
Pt. 8 - Build Quality, Quality Control, and Battery Life
Pt. 9 - Conclusion

I received feedback from a number of individuals who wanted to see the prior high ISO noise testing repeated with some RAW conversions included. I am posting here some prelimanry results of such tests. Of course, RAW conversion is a highly personal process. I have used here Adobe Camera RAW with slight noise removal at ISO 400 and up only, since my main goal here is to show how much extra detail can be retained if one is willing to tolerate noise. Of course if one were to find the noise levels of my RAW conversions to be excessive, additional noise removal could be applied during or after RAW conversion.

As before, I used standard in-camera processing settings when possible. Cameras were set to 35mm equivalent focal length and tested on a tripod with self-timer. Aperture was fixed at f5.6 (f5.8 was the closest possible on the GX100).

Here was the overall test scene:



As always, click on the photo for full size (In some browsers, a second click is necessary to get actual size). Here are the right edge crops:

Edit/Correction - In my haste, I mislabelled the bottom GX100 crop in each set, which should instead be labelled as GX100 ACR conversion.

ISO 80:



ISO 100:


ISO 200:



ISO 400:



ISO 800:



ISO 1600:



I will add the results from the center, left edge, bottom left corner, and bottom right corner later today. I will also add results from Silkypix RAW conversions as soon as possible.

What is didderence between 2 GX100 crops?

Miracle? I see PF in the bottom GX100 pics and don't see it in any others.

Sorry, the bottom GX100 crops are mislabeled. The bottom ones should be labelled as RAW conversions from ACR.

It seems GX100 has in-camera PF correction for JPEG.
