Sonys' new Camera announcement
Jul 16, 2019 13:54:17 #
Sony has just announced the new release of the Mirrorless camera Alpha 7RMIV. 61MP 15 Frames per Second and with the new sensors has the capability of capturing over 256 million mega pixels. The camera is going to be released in September of 2019 and have a retail price of $3500 and $4500 in CA. Sony also announced that they are Number 1 in Full Frame Mirrorless Camera Sales (Lenses and Camera Combined) and Number 1 in DSLR Sales for the year of 2019.

Question about your post:
61MP = 256MP how?
This some new type of technology for sensors?

$39K or $45K... Same thing; no difference to them that's got it.

Yikes, and how do I get by with using one focus point and spot metering for my Flower Close-Ups? Unless this is completely new technology at 61MP the pixels will be so small and close together you'll get diffraction at f/8! Now you can easily print 16 x 24 foot murals and still pixel peek. Useful tool.

In case you have not seen it already here is what you want to know about the new Sony camera.

Wow, after watching this 30 minute presentation I have to reconsider or retract most of my initial comments. For me anyway the 15 stops of dynamic range is most impressive. The focus shift giving the effect of 260MP of high resolution sounds interesting as well. Yikes, imagine combining Focus Shift with Focus Stacking for Macro/Micro photography. I still think one focus / exposure point so those stats never do much for me or burst speed. I mostly shoot flowers and landscapes and sea shell. Usually nothing is moving. But IQ, WB, and fidelity would be important to me. I still wonder about the Quantum distortion effects at that small a pixel pitch per f-stop and diffraction. I did look it up earlier and such a beast might be diffraction limited to f/8 in FF mode. All in all, good work Sony. Note, I am a Pentax and Fujifilm user.

Its called "pixel shift". This technique is used in Pentax, Olympus and Panasonic. And more recently in the Sony A7Riii.
Pemtax and the Sony A7Riii take 4 images, shifting the sensor in 1 pixel steps so that each tiny portion of a scene is exposed to a red, a blue and two green pixels. And then then images are combined. Pentax does it in camera or with post proscessing. Sony with only post processing. The results is greater color fidelity in the image. But not more resolution.
Olympus and Panasonic then proceeded to do one better. They stepped the sensor 8 times in 0.5 pixel steps. And this, in addition to color fidelity, increased the resolution in one axis.
And now, with the new Sony A7Riv, it is going to take 16 images stepping in 0.5 pixel steps resulting in the doubling of resolution in both axis. I assume that this will work in both full frame mode and in crop mode, but I haven't seen it mentioned for crop mode.
This is where the extra resolution comes from. Of course, not every kind of shot can be used this way.

I wonder, at what point, it becomes impractical to keep increasing the pixel count. Canon has produced a 120 megapixel and a 250 megapixel APS-H sensor. APS-H is between APS-C and full frame. Those sensors or similar sensors have never been in a camera on the market. Maybe because the pixels are tiny, diffraction, digital noise, and dynamic range take a hit. Blur from camera shake could be amplified as well.

It would seem there is a pretty simple fix. Since you can probably select how many focus points to use just select a few more than one, i.e. 4. This will allow you to focus and spot meter on about the same area as you would with an 18 Mp sensor. Diffraction is the same for any camera as it is a function of aperature. It may become more apparent with the higher resolution sensor when you pixel peep but will not effect the quality of your prints any more than it does now.

Wow, sure glad you cleared that up for me. I thought he was talking about the California (CA) surcharge for sanctuary cities!! I knew the taxes were high there, but not THAT high!!
Thanks again...

I don't understand how blur or diffraction would be increased. The blur would be recorded over more sensors but the appearance on the image would remain the same. I guess the blur would be "sharper" if that isn't an oxymoron, i.e. more accurate recording of the blur? Diffraction is caused by aperture regardless of the sensor. I am sure that Sony knows exactly what this limit is. By shifting the focus point by 0.5 pixels they may be averaging out the diffraction among other things.

It uses pixel shift technology to take multiple images which are then combined in camera to produce incredibly large files.

Question: How would this much High Megapixels affect the download time on the computer and the ability to work with the pictures and E-mail them?
