Quote:Hmm, I'm not sure about the cost and weight. The Nikkor AF-P 18-55 is available both with and without VR, the price difference is marginal (in absolute terms), as is the weight: 195 vs 205 grams.
Reliability might be a different topic, though. However, at least the gyros should have become a mass product by now (thanks to smartphones).
I still think that it's primarily a question of what type of viewfinder one primarily uses. For anything with an optical viewfinder, ILIS still has clear advantages in my eyes, while combined with an EVF, IBIS offers universal coverage... except for long lenses? Is that still an issue?

From a pure theoretical point of view, adding things can only make a product more complex, bigger, heavier and costlier. However, it doesn't mean you'll necessarily see it in practice.
Manufacturers will obviously keep the consumer price and specs similar to non ILIS versions. From an IQ and weight perspective, they will design it from the ground up with ILIS in mind.
However, it's likely that if they were to going to design it from the ground up without ILIS, it could be made smaller, lighter and cheaper.
Now, about gyros. What is more likely to break : nothing or a gyro ? ;-)
As far as OVF go, IBIS won't obviously stabilize what you see in the VF... and in this specific case ILIS has a clear advantage.
