Where did I discount EIS? EIS+OIS is a golden solution. It's what the Pixel 3 does. It's what the iPhone 8 does. It's what the Huawei P20 does.

This all gets very reductionist, but EIS over a series of bursts is a bad alternative to OIS. It will be garbage in->garbage out. EIS with OIS, however, gives you the benefits of OIS, with the safety valve and "time travelling" effect of EIS (in that it can correct where OIS made the wrong presumption, like the beginning of a pan).

>and even using something like Olympus' top range 5-axis IBIS

The ability of OIS to counter movement is a function of the focal length. Your Olympus probably has a 75mm equivalent or higher lens, where a small degree of movement is a large subject skew. That smartphone probably has a 26-28mm equivalent lens. Small degrees of movement are much more correctable.

EIS is brilliant. OIS is better for small movements, but add EIS and it's great. Computational photography is brilliant. However Google has really, really been pouring out the snake oil for their Pixel line.

50mm equivalent in 135 terms, but yes, larger than 28. (I've since moved on to an X100F, but that's neither here nor there. :)

This is what I was missing. It seemed you were arguing that computational photography is not capable of much, but you're more just pointing out that this computational photography is not doing much, despite Google's claims to the contrary.

I'd agree with you that this is not exactly revolutionary stuff.
