I don't share this opinion. Differences are quiet obvious here. Not in all situations but it's there when you need it. Buying an G6 now unless your into video is a mistake. The EM-10 is an better option

Not if you like the dSLR format and the Panasonic ergonomics. The video is just a bonus ...

And if you are shooting very high ISO the GM1 is better than both ...

Gh2 g5 g6 use the larger 18mp multi aspect. But the multi aspect function is unfortunately disabled in the g models.

Yes, but their video is so good that one presumes that it may still be used for that. For stills, though, you live with the crop. And yet the newer versions of the sensor have much better dynamic range than the GH2 so Panny have probably improve read circuitry etc in these derivatives.

They also changed the image processor with great results in Jpeg. I still prefer an hacked GH2 for it's video capability's especially since FOV will be much wider in video.

Me too ... I like the extremely reliable mid level patch Cake 2.3 since it can span on any card and still gives a nice clean 65Mbps ...

By the way, when I post, it is never with respect to JPEG performance and on with respect to raw.

These sensors have significant less dynamic range at base iso as the new models. Also about an stop lower sensitivity. So ISO 1600 on the gx7 will look about as good as ISO 800 on the g6.

And the GM1 is even better at high ISO ... Panny is pulling rabbits out of hats with their new sensors in this area. Dynamic range is also very competitive.

Indeed that is the point i made somewhere else. Who care who makes the sensor. The latest Sony and Panasonic sensors are to close to tell apart

Except up at the highest ISOs, agreed. For the vast majority of people, there is no difference on that score.

That is a significant difference that closes the gap to most Apsc based camera's. Apsc does still have an resolution advantage since you get similar dynamic range and ISO performance at 24mp.

If you crop for portraits, the difference is about 1/3 stops ... there is no relevant difference.

Or you will get better ISO performance if you choose fujifilm.

Yeah ... sort of. Fuji do a great deal of smearing of their RAW files, so the XTrans units look amazing at 6400 ISO. But look closer and you will see that m4/3 -- despite the much higher levels of grain -- also have higher levels of retained detail.

That is only in lightroom. Which really messes up the Raw rendering of the X-trans. Photo ninja seems to do a better job. The noise is more apparent but very fine of structure. Which makes it easier to get rid off. Details are very well maintained when using other programs. So it's more or less Lightrooms fault here.

Fair enough ... I guess I'll have to believe that ... I have been testing the XQ1 (baby s trans) and found the raw images excellent. But maybe the bigger ones are worse?

The Fuji output in RAW (check the comparator at DPReview) does look seductively clean ... and for JPEG shooters, who are already compromised in this way, that might be a great thing. But I think there is enough extra detail in m4/3 to compete in RAW against the X-Trans.

No there is not. Again lightroom F*cks the x-trans files up.

Not in my experience, albeit that is limited to the smaller X Trans.

YMMV of course ...

It indeed does. I have an 16MP sony sensor of an K30 and an GX7.

I used the olympus 12mp in the past as well as the pana G3.

I can not tell the GX7 quality apart from my K30. Not in details nor in noise. And not in dynamic range

I would agree with that. I don't see how that differs from anything I wrote.

Considering the panasonic sensor is much smaller i am quiet impressed by that. I also had an XE-1 for a 2 day trial. Man i was impressed by that. It really was better without any doubt. However i hated the handling of the XE-1. The screen was terrible and menu's confusing. Guess no camera is perfect. But the GX7 is really really close.

Well, you talk a lot about JPEGs so maybe that's why you liked the Fuji. But either way, I would take m4/3 any day because the bodies offer far more choice and Panny has stunning video ... Fuji just cannot get their act together around stuff like that, although they do have a to die for JPEG engine for sure ...
