Panasonic GM1 compared to NEX-5R. Should I consider switch?

Here's how the sensors of the GM1, Olympus E-M1, and Sony NEX-5R compare:

DxOMark Comparisons

As you can see, your Sony's sensor is better at low light than that of the GM1.

Please don't rely on the overall score which is not accurate in most situations. Instead look at the graphs/actual measurements. You will quickly see that all are very close and almost over lapping, so in real life there will be no noticeable difference. Since the question was comparing an M43 lens with a slightly larger aperture to an APS lens, any difference should be erased.

What is amazing is how much better then E-M1 DR is than the 5R proving sensor size does not dictate which is best.

The OP was concerned about low light performance; that is the particular measurement I referenced and NOT the total overall score. The low light rating for the GM1 is 660, whereas the NEX-5R is rated at 910.

LOL! do you even know that those numbers mean? Which ISO are they for?

Try doing as I said and look at the actual measurements and you will see that at most of the higher ISOs the difference is very minor (the charts/measurements are almost identical) and mostly made up with the slightly wider aperture M43 lens. Also, you will see if you actually look that from ISO 4000 to about ISO 10000 the GM1 has more DR.  Yes, at those ISO with the F/1.7 lens the GM1 would be slightly better at noise and DR.

Again, there is no real life difference except the GM1 has better lenses.
