GM1 vs. Sony RX100 II, almost equal
Dec 7, 2013

DXOMark is slightly disappointed in the GM1's sensor.

The RX100 ll holds up surprisingly well.

The GX7's sensor is the better one.

I upgraded from the GF3 to the GM1 yesterday (yay!) and this graph shows one reason. The sensor performance of the GM1 and RX100 II is pretty much the same, but the former can take other lenses.

Good luck finding a RX100 with a good lens...

That would be the RX10

Can you be more specific? Do you mean the soft corners of the Sony or something else?

I keep on doubting between the two...

I had the original RX100. May have nice. IQ but was blah to shoot. For me ultimate sensor IQ is not the highest priority but does the camera and the experience of working with it inspire me to go out and shoot. In that regard the RX100 was a fail and the GM1 is a home run . So, will you in 99% of your photography see a difference  in IQ between shooting the GX7, GM1 or RX100 (Except DOF with RX100). No. At the end of the day composition and subject matter in an image will trump the DxO score every time.

That's mean you can use prime lens where the sony can't even come close. Did I mention you can change the lens on the gm1?

I think something is off about their measurements with this one.  4 points for identical sensors is a bit much even for dxo.

I am afraid that I don't understand about "4 points".

I like my RX100, the sensor and lens are great and I can carry it when I don't want to carry anything I'd notice I was carrying. YMMV of course.

The GM1 scored 66 points and the GX7 70 points in DXO's sensor rating system, but with the same sensor and image processor you would have expected them to be quite close. Then again the GM1 may get hotter (lowering performance) or just have some less good other Electronics (power supplies, etc.). Who knows?

The Imaging Resource findings differ somewhat from DxO's. Comparing the GM1 with the RX100II at ISO1600, they say "this is where the 1-inch-type sensor of the RX100 II starts to lose ground. It beats most other non-ILC compacts currently on the market, but can't keep pace with the GM1's much larger sensor as ISO rises."

About the GX7 vs. GM1 differences: given that according to Panasonic these cameras have the same--not just similar--sensor and associated circuitry, I wonder if we're just looking at sample variation, in that two samples of either camera might show differences of this magnitude.  In all of the Imaging Resources comparisons, at all ISOs tested, they describe the performance of these cameras as "virtually identical."

I think most of us have learnt by now to take DXO's scores with a big grain of salt.  Their results are at odds with other reviewers sometimes and their methods not fully open and understood.   When in doubt, I just ignore them.

Plus you have the DoF benefit of the RX100 sensor.

Makes sense the gx7 is better, and it seems to be by a margin! can't see this being sample variation, its too much.

It's true that many small cameras can compete with the GM1, and people should be given awareness of that. But more importantly, people should know that the key reason to get the GM1 would be to have the smallest m4/3 camera with interchangeable lenses. It's good to keep these comparisons current, though - thanks.

Based on my GM1's performance I think it does lack some muscle compared to the bigger Pana's, but I'm hoping that will improve with a firmware update.

This point is right on. I own the GM1, but I would be just as comfortable with a fixed lens, since I'm not swapping lenses at this point anyway.

The 45mm f1.8 is a great companion to the GM1. Small, fast and a good focal length not covered by the kit
