Cable release and SR

At occasion I'm reading that when using a remote to take a picture, the SR is disabled. I assume that this for all Pentax dSLR cameras. Is this correct? It however is not clear if this is the IR remote or the cable release. So to which mechanism does this apply?

I did check today on a K10D and a K100D with cable release/2 sec delay and the EXIF still says that SR is on so I assume that it is for IR only.

Thanks in advance

Actually if you're using 2 second delay, then SR is always disabled by default. At least that's how it is with the K-7, K-x and (I think) K20D.

Also, if the shutter speed gets slow enough, then SR is also disabled. (edit: this one is false, my bad)

Using a cable release does not necessarily disable SR. The cable release essentially acts exactly like your shutter button, and that's how the camera sees it. I am not aware if the same is true for the IR remote.

?????

That is a new one to me, at least for my K10D. How slow is slow?

Edit: I found the statement in my camera manual, but it doesn't really say that it is disabled. It does say that it doesn't work very well and that a tripod should be used instead. Even so, I find the statement strange. I thought that the intent was to allow shooting at lower shutter speeds without having to use a tripod. Maybe it is some sort of corporate CYA?

Photographer: "My pictures at 1/8s came out blurry despite SR."
Pentax: "It says in your manual that SR is not affective at slow shutter speeds..."
Photographer: "What is slow?"
Pentax: "Any speed where SR does not work..."
End Edit

(Regularly shoots at 1/8s with the 85mm J-9 with good results...)

hmm, I don't know. I guess I pulled that one out of my ass. I swear I read that in the manual, but I'm probably confusing it with something else.

So to re-iterate, SR does NOT get disabled automatically when the shutter speed gets slow enough

I should have read the manual better Page 68 of the K10D manual states
QuoteQuote:
The Shake reduction function automatically turns off in the following situations.
When using self-timer, 2 sec. self-timer, remote control shooting, 3 sec. delay shooting, bulb shooting, or wireless mode with an external flash.
Thanks

What the heck is 3 sec. delay shooting? Must be a K10D thing...

oops, there goes my sanity again...

then again, I don't have an IR remote, so it doesn't apply to me

...tralala, living in blissful ignorance...

(my IR remote should be at the mailbox tomorrow, though, so my ignorance will soon vanish)
