A 41MP Olympus Mirrorless Camera will be Announced Soon

Recommended Posts

Olympus registered an IM019 camera in Asia during October and the same IM019 was registered in Russia in December for 2 camera kits. That would suggest a new Olympus body would be announced in February timeframe and could coincide with a new sensor.

because they have small pixels and 12 bit is enough for the dynamic range of those pixels

Actually there is a theoretical limit of bit depth with dynamic range. Meaning that a camera with 12 bit will have 12 stops (which isn't true for the GH5 with its 13 approx stops). Maybe if Panasonic pushes it to 14-bit, highlight and shadow recovery could improve.

GH5 has pixel level DR of 12.3EV according to DXOmark, it’s 12bit ADC plus a bit of NR, similar to how S1H achieves 12.7EV DR in video mode.

GH5S is the only MFT sensor with 14bit ADC for stills.

higher ADC bitdepth improves SNR below 18% grey, it does not affect highlight latitude.

There is no theoretical limit on bit depth relative to dynamic range, as they are two independent properties.  On the other hand, there certainly are practical limits (and ideals) as to how much bit depth is mapped to the amplitude range (bit depth is mapped to the range in amplitude -- not to the dynamic range).

Applying bit depth numbers that approximate the dynamic range has become standard practice for feasibility reasons.  However, there is no connection between bit depth and dynamic range -- they are two independent properties.

 

Bit depth is simply the number of digital intervals mapped to a amplitude range.  Dynamic range is essentially the portion of the amplitude range without noise.  Amplitude range is the total range of signal level (including the noise).

 

One can have a camera with a bit depth of 3, but with a capture dynamic range of 16 stops.  Likewise, one can have a camera with a bit depth of 16, but with a capture dynamic range of 3 stops.

 

Indeed, there are many cameras with multiple, selectable bit depths, yet the capture dynamic range remains unchanged in each of those bit depths.
 

By the way, the lack of beer functions was very disappointing.

Thank you gun jumpers ?

I am still sceptical that the e-m1ii would come out so soon after the e-m5iii that has the older sensor.  We will find out soon.

Well, is we are to believe this Simon person from the 43rumors comments, then it looks like the sensor is not changing.  He has had a checkered past in posting correct info on future products, although he is usually close with his leaks.

new MK III will NOT include the sensor (IMX492LQJ) speculated here. This sensor is currently not used in cameras, as all other components to process double MP (20 vs. 40 MP) are not technically (thermally) and economically feasible to integrate. Furthermore, the ISO noise would be too high at the moment.

It will be a 20 MP sensor (sony), with a new and significantly improved coating. The MK III will be a significant improvement over the MK II, but not a revolution.

We will see almost all the features of the EM 1 X plus two new innovations. The good news will be that all accessories of the MK II can be used again. This means that the HLD-9 can still be used. The image stabilization will be improved again. In addition, the MK III will be almost two Iso stages better than the MK II. MK II will have same VF as leica. As expacted screen will be OLED and still using SDXC Cards (no nonsens as Nikon). In direct comp. between MK II / MK III you can see a significant advantage in picture depth. Keep in mind still 20 MP !!

The sales start of the new camera will be Q2 /2020.
All in all the MK III will be the better EM 1 X.

Sounds like Simon is full of shit to me.

”This sensor is currently not used in cameras, as all other components to process double MP (20 vs. 40 MP) are not technically (thermally) and economically feasible to integrate.”

This is word soup.

Almost all MFT sensors as of late have been tweaked variations of industrial sensors, no? Improved coatings on sensors? What are those? Never heard anyone talks about coatings on sensors.

We'll see. They should try and scoop some of the Panasonic users off the market. They've always been a little too stills focused, like Fuji always was too. They're both coming around it seems, but Olympus is still a bit behind. Their advantage is phase detect AF, rather than betting on depth from de-focus and that could sway a whole bunch of people always hating Panasonic for that. Just need more video centric features incl. 10-bit, various overlays and all. Would've been nice to see some new sensortech, but I suppose not.
