I like how the responses are totally different on this forum vs. the same post on DPR.

The test is getting flamed ridiculously by sensor nerds.

Yeah, I saw that. Eventually had to click ignore on a couple of characters.

Yeah...that's because on this forum, we actually have people who care about photography than a bunch of numbers in a chart.

The one thing about DPReview...there are a lot of people there (my traffic from that thread is pretty high, though nowhere near the traffic from the reference on 43rumors)

I only had to ignore one person in that thread...and I got a little too heated myself at the beginning of the thread, but a lot of people over there seem to be missing the point.

It's really quite simple.

The OM-D EM-5 should be better. It's a newer camera with newer technology and is currently the Olympus MFT flagship.

Anything less (i.e. GH2 still "better") would be a failure.

I still like this test and I would like to see more extremely taking something from shadows (+3-4 EV) not only recovering from hilights. I'm not sensor geek but I gladly look on tables on DPreview that E-M5 has same DR as my Nikon D90 :)

Did you look at the whole test? The last part of the test is 3 stop underexposure and shadow recovery. E-M5 is better here too, but not by quite as dramatic a margin.

I was thinking more about whole scene with many colorful objects which is underexposed and then pulled hard in Lightroom....

GH2 has a terrible red channel noise, so when you shoot scenes with a lot of blue in it, you will get good photos in low light... that's the fact.

Sure is! But luckily, I finally stumbled across an OMD. So no more jealousy!

And welcome to the forum Hoggdo!!
Good for you I have Silver/Black Kit on order with OlyUSA. Hopefully I'll have it in hand in a couple of weeks, not holding my breath though!

Enjoy the OM-D it is a remarkable achievement by Olympus.

I bought a Oly 45 MM F1.8 today cause the local dealer had a zero sales tax sale and I couldn't resist...... :biggrin:

My goodness, I just skimmed through the DPR thread. What a flog!

There are "good" sensor nerds at DPR. I'd point to physicist Emil Martinec as an example. Then there are "bad" sensor nerds at DPR, overwhelmingly in the majority. In that particular thread, exdeejjjaaaa is just obnoxious, but I find Detail Man (even) (more) maddening for his (inappropriate) use of parentheses (again and again) throughout his writing (which doesn't make a lot of sense to me even if there weren't so many parentheses).

:dash2: :horse:

After holding off as long as I could from getting the E-M5, this dynamic range test and another shadow recovery test done by Steve Huff on the E-M5 (yes, the Leica guy! :eek:) did it for me...

I developed a huge bout of GAS over the past week and finally couldn't hold it anymore and went out and bought myself a silver E-M5 with the kit lens...

Same here! I ordered one on Wednesday and got it yesterday (silver kit also but I will sell the lens). :biggrin:

I plan on keeping the kit lens since it is the only native lens available at the moment that is weather-sealed...

You will enjoy using that lens! I still can't get over how compact/small it is. But the important thing is how good the image quality, inherent contrast, and color rendition it is.

I love my E-M5 and see no reason to get overly interested in another camera for a good while. The desire to change cameras over and over again stems from a lack of faith in the photographer and a state of denial concerning that lack of faith.

Ok, I finally got a chance to test the E-M5 against my GH2 in dynamic range. I chose a high DR area, and then decided to see how they did when overexposed 3 stops and pulled back, and underexposed 3 stops and pushed back.
I'm late to this thread, but thanks a bunch for doing this. Really excellent test.

Next, I took a look at the shadows. There wasn't a lot of extreme shadowing in the frame, but the bridge above, of course was the place to look. This much shadow recovery is equivalent to a 3 stop push. There is a lot of noise for both cameras in the pushed shadows, that's for sure, but the E-M5 again retains more detail, has better noise control, and retains the rust color of the bridge steel. The GH2 loses the color information and a lot of the darkest detail.
That looks like a fair assessment to me. My question is this - how far can you underexpose shadows without losing fine detail on the E-M5? On my D700 for example, I can get away with around 1.5 stops of underexposure and still have some semblance of fine details after processing, whereas on the E-PM1, even 0.5 stops causes significant degradation. Thanks,

DH
