Rumours that Sony has made a 32MP MFT sensor

If true, that should put a smile on faces here!

That would be consistent with support for 8k in the Sharp m43 video camera.

I had assumed Sharp would make that sensor themselves.

Re: Rumours that Sony has made a 32MP MFT sensor

Interesting; if true of course.

How many here would buy one though?

I do wonder at what point the industry will stop chasing pixels? I could see a real advantage in producing (say) a 20 MP sensor with really good low light performance, (approaching the current Nikon FF sensors for example), but if the new sensor is little better than my present 16 MP sensor in low light I cannot really see the point except to provide better defined noise.

In any case, how many pixels do amateurs, and even most professionals actually need? Is this really about improving photography or simply keeping the production lines rolling?

To put this into perspective, Nikon reckoned that a 35 mm negative could provide little more than 5 MP of usable data [when scanned], whilst 35 mm transparency film could provide about double that figure.

Re: Rumours that Sony has made a 32MP MFT sensor

A couple of points :

1. How many lenses have the resolution needed to deliver the detail the sensor is capable of?

2. The latest mobile phones do have > 40MP sensors that are way smaller than a M43 sensor and they end up doing pixel binning (i.e. combining the output from a 2 x 2 matrix of pixels) to try and reduce noise in low light situations. Maybe that's what Oly could do with this sensor, they can market it as 32MP but in effect, it delivers an 8MP image that has more dynamic range.

Who knows.

I seem to remember reading that Four Thirds and µ43 lenses were capable of resolving up to 22 MP.

Oh, another thought - IBIS is going to have to work twice as hard to cope with this doubling of pixel density or you end up with blurry images.

Who knows.
The 12-40 certainly seems to manage 50MP quite nicely, but possibly struggles at 80MP. Downsampling from 80MP to 60MP yields nice results. That’s... ummm... what I know so far. My suspicion is you can push the pixels as far as you like, albeit with a diminishing return.

Re: Rumours that Sony has made a 32MP MFT sensor

The history of digital photography has shown that increasing pixel count is usually accompanied by lower overall noise, not the inverse. More Mp also gives greater scope for cropping as well as delivering greater capacity for fine detail. It's also the case that any lens will improve as the pixel count increases - it's not as simple as saying that a particular lens "only resolves x Mp so higher density sensors are pointless". That's not true. Personally, I'd value (and would probably buy) a 32Mp m43 camera.

Re: Rumours that Sony has made a 32MP MFT sensor

Lens manufacture is a physical polishing process and subject to many challenges. I doubt the majority of existing M43 lens can resolve to the level required for a 32MP sensor. As far as zooms are concerned I doubt any will be up to it. Hope I am wrong.

If you want to use the Hi-Res features on an Oly camera today you need a tripod and/or a still target. That challenge will get even tougher with more smaller pixels. Hand holding - forget it.

With my astrophotography hat on putting more pixels in a given defined area i.e. the size of a chips sensor means they will be smaller and therefore capture fewer photons per pixel. More dynamic range requires larger pixels to capture more photons in the well. Look at the Sony low light cameras they have big pixels. There is no magic wand however much we wish, its basic physics.

So apart from marketing hype, the benefits are - the potential for higher dynamic range through pixel binning.

Potential for more detail - target and lens permitting.

Noise no change per pixel but a lot lower with binning.

Have you tried HiRes on milky way?

Can't really see it from where I live, unfortunately too much light pollution in that direction. It might work but not sure as the rotation of the earth may be an issue with long exposures. Your milky way shots are great why not give it a go.

Going to Surabaya/Bromo again ..end june. Hopefully I have to chance to give it a try.

I would need to update my computer with files that size though.
