IBIS is one of the everyday miracles of industrial engineering

The back story behind the six second exposure shot of my wife’s garden at midnight
Funnily enough here at my home it is also my "wife's garden" .Though when it comes to the unpleasant side of gardening double digging for potatoes etc it suddenly becomes our garden
was that not only was it hand held, it was done in scene mode using “night scene” with the camera handling all settings, including autofocus. It selected six seconds, 200 ISO, 3.5 aperture (max) and -.03 EV.
i cannot imagine how much better the admittedly soft photo would have been if shot in reasonable light with exposure under a second, at ISOs more appropriate for low light photography.
I calculated the stops and came up with about six stops.
The new M1 3 has better IBIS. Shooting with good glass in daylight, the problem ought to be having the subject stand still long enough to not blur the photo.
I am honestly not intending to be glib Olympus IBIS and the latest Panasonic versions really are superb . For video it is incredible , but as with all tech it has its limitations.
In 1983 I worked at an office that had an IBM Selectric printer, that was replaced in 1984 with a daisy wheel printer. The Selectric was a ball with characters on it that would whirl to the right character, strike the page, and retract. The new daisy wheel printer was much more logical to me, as it was a wheel with all the characters on it that spun only on one axis and then struck the page and came back. When I got my own office I used a daisy wheel printer, although I had one Selectric typewriter to address envelopes (it still works today).
Then about 1987 or so I got a letter that had different size fonts on it, and called my friend who sent it to me and asked how he did that, and he replied he had something new called a laser printer. It cost something like two thousand dollars, and it's somewhere in storage today, and might still work. It lasted until laser printers became so cheap my office assistants would buy one about the way you buy another pair of good shoes.
Bubble jet printers came out later, and they are great but not yet letter grade, but plenty good enough for everyday use. The one at home in our home office cost something like $40 and the pair of cartridges tt uses cost more than the printer if I buy the name brand. At the office the new laser jet color printers cost $400 and the cartridges for them cost $400 for four regular sized ones, and twice that for the extra large. Eventually the recyclers will crack the code on the chips and the cartridges will cost a fraction of new.
Black and white laser jets cost a hundred dollars and the recycled cartridges for them are so cheap I don't remember what they cost. The ones we have are over ten years old at least.
Industrial engineers, are some of the smartest people on the planet. The product has to be able to be produced by the millions, work like a crowbar, not require any service, and last so long the customer wants a better one, and be set aside still working the way it did when new.
The first IBIS on a digital camera was on the 2003 Minolta DiMage A1

It was good for three stops.
How in the heck, does the mechanism stand up to shaking the sensor as fast as it does, and never break, never mess up, and last the life of the camera?
It's a modern miracle, but not any more miraculous than watching the wheel on an IBM Selectric spin around and strike the paper, perfect every time, and never wearing out or needing any service.
The IBM Selectric, came out in 1961.
