Sony & Samsung 48MP sensors arrived...

Recommended Posts

EOSHD Pro Color for Sony cameras EOSHD Pro LOG for Sony CamerasEOSHD C-LOG and Film Profiles for All Canon DSLRs

To my book, this is the most crucial hassle I see to this device to pair or even beyond Trump's persecution, at least and IMHO:

On the other hand, this is the most interesting deal to me so far, Sony's sensor beats Samsung's:

To those in Europe, as for instance, to have the need to use the 800Mhz band mainly outside downtown (once Redmi Note 7 Pro was not introduced other than China and India to not cannibalize the Xiaomi high-end) here's a much interesting alternative based on the superior Sony's IMX586 sensor -- seems Camera2 API compatible:

 

 

Support directly from YT with firmware updates introducing new features looks like very customer friendly too -- you definitely won't have that going along a major player:

According to this latter reviewer to conclude the acquisition and image processing performance is not much enthusiastic either without mention: "It is possible to install GCAM on the S3 Pro but you have to unlock the boot loader", so...

...let's wait for some reviews on other models such as Meizu 16s to use this Sony's IMX586 sensor.

IMHO I am not sure one would actually be able to compare the quality of the 48MP sensors of Sony and Samsung. Processors, processing algorithms, and many other things dictate the quality of the final image. Unless 2 smartphones have absolutely identical everything in hardware and software, and the sensors are different, there may be a way to determine image quality based on image sensors alone.

The Gsmarena.com comparison also didn't seem perfectly fine, for the S10, where they compared processing capabilities of the Exynos and Snapdragon. In one of the pics I found the Exynos version to better (I think there were like 4-5 pic comparisons). I felt  there may be angle of view that triggers the level of HDR and exact colours.

I obviously agree with you : ) The point is when you see the Redmi Note 7 Pro (IMX586) and the 7S (in India, without the letter S for the rest of the world) with the Samsung version, then you see Sony's beats the competitor.

Smartphones with the Camera2 API provides up to 200Mbps bit rate + log higher DR + manual settings. With a competent sensor, you're able to match a decent outcome. Amazing combos IMHO : -)

Maybe I should try and check whether Camera2API had been installed (/activated), from the factory gate  or it needs some manner of a hack (root your device).

If i have the time, and find a Xiaomi store close not too far away, I will try and figure this out. Ig I get my hands on both devices (having different imaging sensors), I will share pics here. 

No promises though. Have to make too much effort for it. And I am not a big fan of Xiaomi either.

That comparison video up there hints the findings I guess you'll reach. God bless India because either Bollywood, digital projection (I worked with Qube in their European expansion), now these revolutionary devices, the contribution of your market is priceless and unique to the world, this industry and the digital age in particular (E : -)

He attempts to praise the Sony sensor, but I found the Samsung one to be doing better. 

Which means the sensors are most likely almost perfectly equal, and other hardware and software makes all the difference. Plus the Samsung one handle shake better, so maybe it has OIS (?) or its shake algorithms are better.

I am guesses all these are Samsung designed sensors and they are being manufactured at the Sony facility due to some stupid laws and taxes in certain parts of the world. Or something even more ludicrous.

Samsung is a little guarded about their sensors and that includes the GM1. Therefore one can never get complete specs and features details about their sensor. 

IMHO the Sony and Samsung sensors have exactly the same specifications and if someone says otherwise, it may not be true. Most likely Samsung has designed the 48MP sensor, (correctly) expecting an overwhelming response for it, plus using the way more effective advertising network of Sony, and also having Sony manufacture its sensor at their facilities along with Samsung, since it's own manufacturing bandwidth may not suffice.

From a bare reading, both have 30fps at Full Res and also have Quad Bayer/ Tetracell technology for having 4 adjacent pixels into a single one  with different exposure timing(?) helping the equivalent of HDR, but using different pixels, instead of the same one at different exposures. I could obviously be wrong, but I am guessing no SoC and Computational Photography algorithm has been able to push the sensor capacity to it's full extent. The sensor could actually have more dynamic range then the 1.4 micron dual pixel ones that the majority of flagships presently have. Plus with 30fps Full Res it could also combine both dual (or quad?) exposure pixel HDR (in the GM2 and , as well as exposing the same pixels at different exposure values at extremely short intervals. If any SoC could do this (which would require ENORMOUS processing power), it could have some seriously high dynamic range.

Considering that Samsung is the largest consumer/buyer of smartphone sensors, and that they do innovate on sensor designs (collaborating with Fuji among others?), there is a likelihood that this Quad bayer/Tetra Pixel sensor is an joint venture between Samsung and Sony. Dual Pixel also seems like a Samsung invention, as the much faster PDAF in the latest 64MP and the new 48MP sensor (2nd generation).

I just wish Samsung would share complete specs of their sensors.
