I was testing through my lenses and I found that when I mount the 200mm onto the 5D3, the IS makes a weird clinking sound when
1. I let go of the shutter button
2. AI Servo
This does not happen on my 5D Mark 2. Has anybody else experienced this? What is confusing to me is that it only happens with the IS- which shouldn't be different among bodies.
EVERYBODY WITH THIS COMBO- please post on this thread if you DO hear the noise or DO NOT hear the noise. This will help with a firmware update or so to fix this problem!!!
What does it sound like?
More like loud clicks. Buzzing or swirling is the gyroscope (that is normal). But this more like a hard click click click sound.
The strange noise that IS makes on 5DMkIII, is it only on startup/shutdown, in operation or can it be related to IS element parking brake application ?
I think this is only on startup/shutdown of the IS. With AI Servo- the startup/shutdown seems continuous therefore making the noise always there.
Is the sound qualitatively different, or just the volume of it is higher ?
It is different- it is like a CLICK CLICK sound not just the gyroscope spinning.
Does the IS stabilize the image OK ?
Yes- IS stabilize OK. No problems with it. Just the CLICKing worries be- because it doesn't sound too friendly with the noise.
