Milky Way using Sony pixel shift tech

This is 2 sets of 4 pixel shift images using a tracker and a Sony A7r3.

Pixel shift is a function of the image stabilisation system where the sensor is shifted 1 pixel each image then they are stacked so there are 4 images each of red green and blue pixels. Its quite clever. It results in a 4 x 42.4megapixel image = nearly 160 megapixels and deeper colour.

hehe, who knows.

It seems the photographic industry is moving towards computational photography like the new Applie iPhone 10X s.

Yes I think it is a useful feature and I intend to use it more often. When Sony first came out with it I thought it may be just a gimmick but it has its uses.

Great result, and an obvious tick of approval for sensor shift. Nicely done, again.
It appears to be pinpoint across the centre top to bottom, and trailing on either side. But a pretty pleasing result, and at that resolution you can cut the centre out and still have a huge photo.
What was the lens you used used Greg?

I have wondered with these type of cameras just how much of a bump would be needed to set the whole system out of alignment. If that's possible.

Thanks Trevor. The Zeiss Loxia 21 F2.8 lens is the one I used here. I think I forgot to use the lens correction in Lightroom. It corrects for any residual distortion as I don't recall getting corner aberrations in previous use of that lens.

I'll make sure I do the lens corrections next time. I don't think its a misalignment. Its a very high quality, well built but compact lens.

Greg.

Its only on the A7r3.

I would not be surprised though if Sony adds it to later models as they tend to include everything they have in each model rather than cripple models to protect more expensive models like Canon does.
