Interesting, I always assumed the "on" switch means, well, on (I tend to ignore all those little warning lights
). So I dusted off the manual...it warns it won't work within 2 seconds of starting up the camera, then buried a bit below it states to wait for the icon when you half press (less obviously - it doesn't actually warn you it won't work
). Which led me onto a google search...
"Performance capabilities such as auto-focus speed, shutter lag time and continuous shooting rate are unaffected by the SR system because its operation is instantaneous, occurring within the normal exposure interval." - from the Pentax SR pdf.
Thanks for pointing this out
Thankfully most shots where I needed to keep the camera still involved me half pressing anyway for that short moment (to reduce
physical shake) anyway.
I am going to test this though, the way it is worded isn't entirely convincing (for me )
, it reminds me where they say not to use NIMHs in your AA Pentax dSLR when they work fine.
I also didn't know 2 second timer disables SR automatically - useful.
Oh the benefits of reading the manual
