FWIW: When panning, with the K-5 and earlier cameras, the SR Icon stays on all the time if you have turned on the SR. With the K-5 II, K-5 IIs, and the K-3 the SR Icon turns off when panning. Stop panning and the SR Icon comes back on. Very slow panning with the K-5 II, K-5 IIs, and K-3 and the SR Icon will stay on.
Now, I have no way to check it out because there is currently no birds for me to be shooting at. What I would like to check (if someone else can do it for now) is set up the same settings for a sort of fast panning with SR turned on, on a K-5 versus a K-5 II, K-5 IIs, or K3. Then compare the resulting images. I am fairly certain that the K-5 images will be blurry. However, I am not so sure that the ones form the other cameras will be blurry.
I know we should turn SR Off when panning with the K-5. However, I am wondering if it is done automatically for us with the K-5 II, K-5 IIs, and K-3.
If no one cares to do this that is OK. I will do it myself as soon as the birds are in the sky again.
