I own the GX1 and like it very much. It cannot compete IQ wise with even entry level DSLRs like the D5100, D3200, and the K-30.
If that is true, then you may be needing a skills upgrade. The GX1 does in fact compete easily with last-generation (and probably current generation) APS-C in many circumstances. Try shooting RAW, for one thing.
First of all , I only ever shoot RAW.
But what do skills of the photographer have to do with measured performance? In no measurement on any of the testing sites, does a GX1, with it's extremely weak DR and color depth reach the levels of any of the above cameras. At high ISO, the GX1 is still behind a old DSLR like the D5000. You can parse DxOMark testing numbers anyway you like, you won't find the GX1 leading in any IQ category vs the above APS-C DSLRs.
And without the add-on EVF, the GX1's LCD for composing images, and for good handholding technique, simply cannot compete with a DSLR.
In almost all circumstances, the difference is irrelevant. I can even hand hold longish lenses, it comes down to technique and there are many ways to improve your stance or brace the camera. Still, I prefer to use my G5 or GH2 when I want to shoot long lenses so I can plant against my eye, but that different has everything to do with the EVF and nothing to do with any inherent dSLR advantage.
I'm not going to get into the specifics of high ISO, color depth, and DR, but even the top-of-the-line EM-5 and GH3 do not equal the current or last generation of entry level DSLRs like some of the ones I mentioned above.
You need to learn how to read those DXOMark graphs ...
What you should note in that graph is that the comparable ISOs are one bar apart, with the OM-D at the left in every case. And since that point is higher than the same point for the D5100 (same camera ISO), you will come to realize that the current m4/3 generation has equalled or eclipsed the last APS-C generation. In that particular graph, the OM-D is about 1/3 to 2/3 stops ahead at each set ISO.
Talk is cheap. Show us where the EM-5 exceeds the D5100, the K-30, or the D3200.
Really, you need an informational adjustment as you are spouting some inaccuracies and misleading people here ...
Again, you can parse the graphs anyway you like. You can choose Print or Screen. At no point do the EM-5 match or exceed the performance of a camera like the D5100. And for ISO, the only reason the EM-5 is anywhere near the D5100 at all, is because Olympus dramatically overrates their ISO ratings vs the measured value. That is a fact.
I never said the EM-5 isn't a good camera, but Sony wasn't able to defy the laws of physics with their m43 sensor in the EM-5 by getting it to perform better than their APS-C 16mp Exmor. Parse the test numbers anyway you like, if the EM-5 sensor performed as well or better than the above cameras as you claim it does, then it would be ahead of them in the sensor ratings. It's not.
Choose Print or Screen, the D5100 is consistently outperforming the EM-5 in the lab. Look at a current APS-C DSLR like the D5200, and the performance advantage for the DSLR will be even more dramatic as now you have a resolution advantage, and the same or better high ISO, color depth and DR advantage that the D5100 had.
The only one who is misleading people here is you.
