Originally posted by Bertrand3000 I used to own a K100D Super but it was long ago. Perhaps I misremember. Anyway, on the K-S2 and on the KP, the release is purely mechanical, only the user can free the internal flash on both bodies.
On the K-S2, my safe upper ISO limit was 1600. Even if 3200 was perfectly usable, I thought noise could be easily seen. But yes, it depends a lot of people, and also a lot of what you are actually photographing.
I have confirmed that many models had this feature in the auto/green mode but all of those had electronic latches using a solenoid. The k-s1 and k-s2 use a mechanical only latch. The upper end models seem to not do this also. I’m assuming because there was an assumption that the users know what they are doing.
It’s pretty easy to see which cameras have a mechanical pop up. First the button is on the side of the flash area. Second when the flash is popped up the button will move the release catch repeatedly if pressed several times. In addition, the button works with the camera powered off. The older models with electronic release generally repositioned the button to the back and these only operate with the camera on. Additionally while the flash is up, pushing the button doesn’t move the release level as far as I can tell.
I can’t recall if I mentioned the pz-1, if I did and if I said it popped up I think I was wrong. The release functions without any batteries in the camera which makes me think they wouldn’t have two different mechanisms to release and that one is purely mechanical.
