If you provide some kind of evidence as to why it should be left off, this would seem more reasonable. SR is for a specific condition, that being, when your hand is touching the camera. The rest of the time you can turn it off.
Even putting your finger on the shutter release button to trigger the shutter on a camera mounted on a tripod can cause enough camera movement to degrade an image. Unless you are shooting hands free and vibration free (mirror shock).. SR should be on.
One of my big complaints with SR, is I can't turn it on for the 2 second delay. Even a remote isn't workable if there is going to be mirror shock. I've had my camera out on nights with a light wind and seen my camera shaking because of tripod movement while on the timer. Unfortunately my only option is to take hand held shots, because I can't force the camera to use SR while on the 2 second delay.
I often shoot a burst with SR on, doing macro or telephoto hand held, Much of the time my hand movements exceed the capability of SR and I get nothing. But because I shoot a burst, if I shoot a four shot burst, on one of them the camera might be still enough to get me an image with the help of SR. Without SR I'd have nothing to show for my efforts. But then, as with anything, I always use the limits of technology. Always lookingg for the easy path. If others want to live in the past and ignore the benefits of SR, which I often find to be just astounding (my picture above is a fairly classic example, an image that in the days of film would have had to have been taken with a tripod but today was hand shot standing up in a public space using SR and a .3 second exposure)) I actually have no issue with that. What I do have an issue is with if people giving advice to others based on antiquated film era ideas and thought processes, while offering no evidence to suggest that what they advocate has any basis in the empirical world, beyond the musings of a few dreamers discussing things they haven't researched. There is always what might be and what is.
If real world examples don't exist, whatever it is you are discussing, it doesn't exist in the real world. I kind of feel like this whole discussion of SR ignores that maxim. You can only waste so much time speculating about how things work. And I have to say, some of what has been posted is science fiction and should be labelled as such. For example SR slows down your burst rate. I get 8 FPS with SR on. What slows down, your burst rate is too slow an exposure or using continuous AF. Honestly, why do people waste so much time inventing reason why not to use SR?
What is it about SR that stops people from thinking they need to test it, to understand it?
Believe on one who can't provide solid test data, test everything.
