You are still confused. There are two relevant comparisons. One is testing for shutter shock, by comparing mechanical shutter with e-shutter. The other is testing the effectiveness of IS. You said in your previous post that the 18-150 lens doesn't really have 4 stops of IS. You claimed to back this up with a test you did a while ago on a different lens using a tripod. So, doubly confused. You used a tripod to test the IS, and the test you did was on a different lens from the one in question. If you think you can come to any reliable conclusions about how effective IS is by doing a tripod-mounted test, then no, you don't fully understand what claimed 4 stops of IS means. Now, as to your other claim, that we need to do tripod-mounted tests to determine shutter shock, that is a different matter. Your objection to R2's demonstration centered on your claim that a handheld shot at that shutter speed (1/60) and focal length would suffer from camera shake, rendering the comparison of e-shutter and mechanical meaningless, because, presumably, both images would be softened by camera shake, so we wouldn't be able to detect any further softening from shutter shock. As I pointed out, though, 1/60 at that focal length with IS enabled is enough to eliminate camera shake, contrary to what you said about the IS not being enough. And it is. It is equivalent to 1/1000 without IS. Furthermore, as others have pointed out, R2's images were very sharp. So, even if, somehow there was still a bit of camera shake covering up whatever softening there might be from shutter shock (on the mechanical shutter shot), that he can get results this good handheld with mechanical shutter demonstrates that whatever theoretical softening there might have been from shutter shock is entirely trivial.

the op just needs to use e-shutter more often and give it a rest
