GX7 sensor vs. EM5 or EM1 sensor

Feb 5, 2014

What is supposed to be the difference between these two sensors regarding rendering or IQ?

Really, they are so close to each other than you can consider they deliver the same IQ.

Worrying about the sensor performance is no longer relevant. It's apparently all about Shutter Shock now

Seriously, IMO the glass in front of the sensor or the eyeball behind the sensors are more important.

My take from personal experience: GM1 (same sensor as GX7) has similar amounts of noise in low light as E-M5, but the noise is "nicer" looking. And there are as far as I've seen no signs of banding when using the Panasonic 20/1.7 on the GM1.

Both sensors are very good and I wouldn't choose one over the other based on IQ.

The E-M1 uses a different sensor.

How they're wielded. Output is comparable in practice, for still anyway. Feature sets, styling and controls is where they significantly differ.

I prefer the Gx7 of these three, others will have a different choice.

Does the real world GX7 vs OMD sensor perform more favorable in low light vs DxO

What about DR on high contrast shots? According to DPR and DXO, the dynamic range is considerably higher on the EM5 vs the GM1 (closer with t he GX7). Plus the curves are much more gentle that reduces clipping. You have both cameras...any thoughts?

Probably not (but I have a FF Sony A7 for low light).

It is still pretty good in low light though and the AF works at -4 EV! (metering is less).....I just like the GX7 over the Oly's.

Thanks. I've been debating em10 vs gx7 back and forth. i'm more than likely going gx7. seems like i'd get better video, no hump vs oly's better jpeg colors, ibis for video. the price difference would allow me to add a prime sooner...low light i can't swing the sony a7 lol. not with the cost of diapers piling up ha

DxO reports a much larger difference between the GM1 and GX7 than is reasonable for two cameras with the same sensor. With no independent verification, I think it is wise to ignore dubious results.

Live blinkies, the single most important feature in nailing exposure, are unfortunately only available on Olympus cameras. I think that's much more important than any sensor difference between these cameras.

I am not sure about that..

In reply to Ulric • Feb 8, 2014

The sensor read out, the circuiry of the GM1 might be different. Also: it is only the dynamic range of course. The other paramters are identical. But the DR is significantly lower.

What is more important is that the DxO consistently (now) reports that the same lens perfoms worse on the GX7 and it is a significant difference....I would try to look into that more but it seems difficult to assess....and then we can argue: if it is so difficult, it may be significant in numbers but not so meaningfull in reallife...

May sound strange but another forum posted that omd em1 uses a panasonic sensor ?

So if true you can bet that the gh4 will be the next latest and greatest cam for stills and video m43 division

Yes, or the measurements may simply be off.

I've read on several forums that all the OM-D series sensors are Sony. I also think that Olympus is adding focus peaking to all the OM-D series because Sony has gone into partnership with Olympus and Olympus will be adding a focus peaking feature to the E-M5 via a new firmware update soon.

Well Zenzu11, I was looking back......where did you get/got the information of firmware update and focuspeaking?

Now it's 2020 and version 2.3 latest with still no focuspeaking.

Do you have the EM5 as I have? We are both waiting among others for the 'peaking' of Olympus technicians if they will hack our systems...

DxO PureRAW 3 review: Give Adobe's apps a much-needed boost with modern AI algorithms

Adobe Photoshop and Lightroom impress in a lot of ways, but their noise reduction lags the competition and their lens corrections lack a real-world basis. DxO PureRAW 3 aims to come to their rescue without totally reinventing your workflow!

The Sony ZV-E1 is the company's latest vlogging-focused camera: a full-frame mirrorless camera based the FX3/a7S III sensor, aimed at YouTubers and 'creators' looking to go pro.

The Sony ZV-E1 is a full frame camera targeting YouTubers. Chris and Jordan are Youtubers, what do they think?
