Pixel binning vs bigger pixel camera? Models that use it?


Recommended Posts

Hello. I wanted to know if pixel binning works in mirrorless camera‘s to boost sensitivity as do larger pixels or it has no significant impact on signal gain? Which models support pixel binning? Maybe there are other techniques that help boost low light performance without resorting to longer exposure times?

Didn't know, thanks for the correction

The A7 IV was added via firmware, A1 had it when I bought it, although it'd already had at least one update, so I don't know if it was there on initial release.

I'm interested in high ISO settings even above 102400 for cases where light is extremelly scarce.

Photo or video?

Where I can find database specifying pixel binning supported models?

I guess all models released after the A7Rv have it, and was apparently also added to A1 and A7iv via firmware. But I daren't make any claims on this anymore 😉 Google is your friend.

With my A7RIV I rarely have noise issues.  But if I am shooting high ISO in a dark environment I will run the RAW through the denoise on my computer before downsizing it with the same software.  I know it isn't in camera and it isn't automatic but it is VERY effective!  The cameras that have this built in is doing the same thing as far as downsizing the JPEG from the original RAW. 

Maybe I am wrong but I doubt the A7RV, A7IV and A1 will output a downsized RAW file?

The problem with the reduced resolution files is that they are not RAW. They have been de-mosaiced. So you don't get regular RAW processing on these files.

To get optimal results I'd prefer to shoot the native resolution, process it as a regular RAW, and then down-res the result.

They are Small, Medium, and Large RAW. And if needed, turning off de-mosaic in your software isn't that difficult.

No, they are not RAW. RAW files contain single colour samples taken at each of the sensels in the sensor.

These files are some half-way stage between RAW and fully processed. They are not accepted by a variety of de-noise processing software which requires RAW files.

Even the software which does process them has certain limitations, precisely because they are not RAW files. 

Use them if the idea of having smaller files appeals to you, but don't pretend that they are true RAW files.

Cite please. Not going to argue about it, Sony says they're RAW.

That kind of goes against my definition of RAW but if it works for you... cool!

Not sure exactly what that means? Do you know what it means? Sony says it's RAW, not lossy RAW, not compressed, not jpeg, not HEIF, but RAW. So, unless and until someone can show me a cite stating that it's not, then it's RAW. It doesn't matter if anyone defines it as RAW or not. Show me a cite. 

For the record, I don't use them. I didn't buy a 50MP camera so I could shoot 20MP.

I guess if you're a purist who defines RAW as the actual raw data produced by the sensor then people have a point: M and S RAW formats are post-processed in camera, where the initial 60 MP of data (in case of A7Rv) is downsampled. The downsampled pixels contain RGB data instead of just R, G or B as it was in the full-size RAW. Does it matter? No, you can just process M or S sized RAW images as if they were shot natively, with the same post-processing headroom. Shouldn't matter much whether you post-process a 60 MP RAW image and store it as 26 MP, or take a 26 MP M-sized RAW and post-process it to your liking.

    • How are you liking your ZV-E10?  Do you use it for still photography, video or both?  I would enjoy hearing your feedback! The A33 was my first digital ILC (interchangeable lens camera) and I still use it a good bit for when I am taking photos specifically for posting online.
    • Hello guys, here I share my impressions of the Brightin Star 11mm 2.8 fisheyelens for night photography, and share some photos taken with it at the end of the post.   Introduction The Brightin Star 11mm 2.8 is a fisheye lens, with manual focus, which is available for different mounts, including Sony's E mount. It is a very interesting lens because of its focal length, large aperture and price - it currently costs just 213 euros (https://brightinstar.com/products/brightin-star-11mm-f2-8-full-frame-wide-angle-starry-sky-fisheye-lens-suitable). After some time using it with the Sony A7IV, here are my impressions of using it. Construction The construction of the lens is excellent; it is a tremendously robust lens, made primarily of metal. It weighs about 600 grams but, even so, it has a contained size compared to its competitors (such as the Samyang or the Astrhori 12mm 2.8). Its diaphragm ring, which is located on the front of the lens, has no clicks. Behind it is the focus ring, and it is followed by a (focusing) scale that is a great help when shooting at large apertures, especially at f2.8. The construction of the lens is generally very good.     Image Quality The image quality of the Brightin Star 11mm 2.8 surprised me. It is a lens that, despite its price, is super sharp, especially in the center of the image. That sharpness drops off, as expected, in the corners. And although its sweet spot is at f5.6 to f8, it performs very well at f2.8, which makes it an ideal lens for night photography. As for vignetting, it is present at full aperture, and fades (without disappearing completely) as the aperture closes. As for chromatic aberrations, they are significantly present, but are easily correctable in processing. Regarding other distortions, it has the fisheye distortion, and some coma in the corners at full aperture. Finally, as for flares, I did not notice any special flare in the presence of lateral light sources. All in all, image quality is a plus for this lens.   Sunstar Another of the lens' strong points, in addition to its sharpness, is the sunstar it creates. This sunstar appears easily from f4. It is 8-bladed and very beautiful. This is a feature to take into account as it can be used as another element to compose with when photographing the sun, the moon or some other point of light in our night photography.   Use Due to its 2.8 aperture and the good performance at it, the Brightin Star 11mm 2.8 is a very interesting lens for night photography. Personally I have used it mostly for floors, combined with a longer focal length (previous pictures) to get the milky way in more detail. But even so, because of its wide angle of view, I have also found it useful for panoramas, since with just 6 vertical shots you can cover 240 degrees.   Conclusion The Brightin 11mm 2.8 is a very economical fisheye lens that performs very well in both landscape and night photography, both for simple shots (correcting its distortion) and for panoramas. It stands out, above all, for its build quality, performance at full aperture and for its beautiful sunstar that comes out easily from f4.   I got it at the official website: https://brightinstar.com/products/brightin-star-11mm-f2-8-full-frame-wide-angle-starry-sky-fisheye-lens-suitable-for-l-sony-e-nikon-z-canon-rf-mount?srsltid=AfmBOor8dl4EwqFJ5z6IUvL5VPiwkVKfjhW0r90r8MDCQR6AscZER9j0   Here I share some photos taken with it (the first two, only the foreground was tanken with it; the thrid one, all the photos of the panorama were taken with it).
