GX8 rumours - 20Mp sensor

http://www.43rumors.com/ft5-first-im...nasonic-fz300/

Rumour on the street is that the GX8 will have the new 20Mp Sony sensor. If true, I think it's more than probable that the E-M1 mk II will have it too.

Re: GX8 rumours - 20Mp sensor

It will be interesting to see how well the 20MP sensor will perform since the pixel size will be 3.3um whereas the 16MP sensor is 3.7um.

Re: GX8 rumours - 20Mp sensor

Let's make an assumption that the rumour is correct...

I find it interesting that Panasonic is championing the reduction in sensor resolution in its latest TZ70 travel zoom compact, reducing resolution from 18MP to 12MP in order to improve low light shooting capability.

Re: GX8 rumours - 20Mp sensor

Ian - I guess it's entirely possible that the rumour is incorrect. Personally I don't want higher resolution - lower noise is much more important to me. If a higher res sensor means higher noise I for one will definitely NOT be buying it!

Re: GX8 rumours - 20Mp sensor

I've also read the rumours. Implications are it's a Sony sensor - but Panasonic 'make' their own normally. Commercially it doesn't make sense. Also increased number of photosite for the same surface area will inevitably reduce dynamic range; well size must reduce as a consequence. What's required is an increase in photosite area, not the other way around. M4/3 set a limit, any break through has to come with technology innovation, which will come in due course.

They didn't make their own for the GH3 though as I think they used the same Sony sensor of that in the E-M5 in the GH3, but then Olympus used (basically) the same Panasonic sensor in the E-M1 as the GH4.

Re: GX8 rumours - 20Mp sensor

The GH4 also uses a Sony sensor, I am reliably informed. By the way, you can increase the sensitivity of the sensor at the same time as increasing the pixel count (and therefore the resolution) - it's all about reducing the wasted area surrounding the photosites on the surface of the sensor.

Re: GX8 rumours - 20Mp sensor

Hmmmm, interesting.

Any wild guesswork about the likely effects on improved CA capabilities of this sensor? Doesn't sound entirely promising to me, but I'm no expert on this sort of thing.

Yes indeed, I'd made the assumption (with emphasis on the last word) that the die was optimised, after all you want the light sensors close enough to be consistent with the shortest wavelength.

Re: GX8 rumours - 20Mp sensor

The Image Quality of the end product is all that matters. My biggest prints are 20"x16" and with a 4k TV possibly in the future, pixel count has become of little interest.

Still frames from 4k video could be of interest...

Re: GX8 rumours - 20Mp sensor

Now the big news is the lens.
Tommorrow Panasonic will announce an 100-400mm lens:

Will be a very nice lens for photographers.

Re: GX8 rumours - 20Mp sensor

Thanks for posting that Ian. It looks a very interesting camera. I'm particularly interested to see the noise and DR results. If they are a step up and the new EM1 MK ii has a similar improved sensor then I'll probably spring for one (EM1 that is). The side flipping screen isn't to my taste though - I often shoot from the waist with the screen flipped horizontal and doing that with a side-flip screen means making the body effectively twice as wide; cumbersome and less discreet. I really hope they don't do the same with the EM1 mk ii. Dual IBIS looks intriguing, but I'm finding it hard to believe it could beat the EM5 mk ii!

Whoa - that's expensive! If it's like other Panasonic cameras though, it'll be 500 within a year.
