OM-D "rendering images like film"?
I've seen this statement on the Phoblographer review of the EM5 and it had me thinking.
Here is the link:
Review: Olympus OMD EM5
First of all, design wise, the extra latitude in the highlights (some people say they cannot even blow the highlights, even if they try), supports such a claim.
Then, there is this "crazy comparison" on Steve Huff's page:
Crazy Comparison! The Olympus OM-D E-M5 vs Nikon D800 vs Leica X2 for High ISO | STEVE HUFF PHOTOS
From what I can see on 100% crops there, the EM5 seems to even have a noise signature similar to film grain characteristics.
What do you owners of the EM5 think? For me at least, such "image character" is very desirable.

The images, even at ISO 200, have a fine grain look to them. As a film shooter (still), I like it.

I think that saying that it is impossible to blow the highlights on the E-M5 may be a little excessive, but I definitely feel that it is better to overexpose rather than underexpose and the sensor lets you do just that. The E-M5 does indeed have a reasonably fine grain profile but it can start to get a bit chunky in darker shadows when you push them (hence my choice to overexpose rather than underexpose). If we're talking purely about the quality of grain/noise I think I'd have to give a slight nod to the Canon G1X over the E-M5, but taking other aspects of sensor performance into account the E-M5 would come out in front.

Yeah, it looks remarkably good. When there is noise, there is rarely any chroma noise. This makes the noise less objectionable.

Thanks for the answers!
What intrigued me (along with seeing several samples) is that the way they designed sensor performance is quite the opposite of several other cases in DSLR cameras (and not only). Where there is more dynamic range in the shadow areas. Since ANY sensor will have highlight priority in capturing detail (this is how Bayer sensors work), perhaps this is a safeguard measure of sorts. Olympus' approach thus goes against the maxim "don't blow the highlights". I don't say it's impossible to blow them, but don't having to worry to much about them is precious. And, photoSmart42, I shoot film too. With an Olympus OM.
This is another nice characteristic. Chroma (as well as "long shutter") noise is the most bitching thing to clear in PP. There's always a tradeoff.
