Sparking sound in long exposure

faisalee · 1st July 2008

Hi Guys,

Was just clicking my IR modified K100D @ home last night and noticed, in a long exposure like above 1 second I hear a sparking sound from within the camera

I tried an even longer exposure like 10 sec and noticed its still there!

Scared to death... I tried the K20D for an exposure of 10 sec and noticed same very prominent sparking sound as if some thing being fried on a pan in lots of oil

Is that normal! I have been using digital SLRs for 5+ years and have never noticed this before

Thanks,
Faisal.

is your SR on?

there will be a sound, but not a sparking one?

Yeah, SR is suppose to be off when mounted on a tripod as stated in the manual.
Else it will cause your SR system to go into some positive feedback loop and go haywire (just kidding).
But I never had any sparking sound with long exposures.

When I take photos w/ tripod, I always use 2sec mirror up. This would set SR off automatically

And then with a

Its not really a "Sparking" sound but more like a static kind and it just "Dawned" on me that its the SR in action

Of course I would not use the tripod with SR on, I was testing handheld...

ZZ ZZ ZZ sound was caused by the shake-reduction mechanism.
