From my experience with my older canon 6D setup was that lens Is did cause very noticeable issues.
However it was on zoom lens’s so not really ideal for the setup.
With the a7rii the IS is better when combined with a good compatible lens.
It does and can cause issues, anything that manipulates the images can make hard work for the software and cause issues.
That said the advantage you get from IS means you can get sharper pictures, or as castle states a lower iso (less noise) from the same exposure time, or allows you to reduce the exposure time, which really helps when hand held.
So it’s a trade off between the two.
The software works best with sharp low iso images, but doesn’t like IS.
If you turn off IS your more likely to have to turn up iso (more noise) and/or have a longer exposure time (more blur).
Which is best ?
- It’s situational, lense, available light, handheld/tripod all make a difference and something that I do aim to do tests with and provide datasets for (benchmarking V2) that won’t be today
The A7rii Is a awesome camera, it’s expensive and so is good glass. It’s not as nice to use as a cannon, but miles nicer to use than my sigma dp0 (foveron) which does incredibly accurate shots - perhaps better than bayer cameras… for this application, but is not user friendly at all.
