Originally posted by Professor Batty I am well aware of the rolling shutter effect. It's a feature, not a bug. Graflex cameras from the twenties and thirties could produce it. I have taken thousands of pictures with the Q's electronic shutter and have had little or no problems with it, although I don't take pictures of fans or helicopters very often. Your phrase "meaningful" is what struck me odd, is that like philosophy?
I never said it is a "bug" - it is a fact of life.
I take many pictures of objects in motion, so my Q-7 is set so that it always uses the leaf-shutter if it can.
The first picture I posted here demonstrated that effect as the bird-feeder bounced in the wind and I was using an adapter without a leaf-shutter to help the "electronic shutter".
The original exchange was as follows:
Originally posted by Professor Batty The electronic shutter on the Q goes to 1/8000
Originally posted by reh321 I'm not sure these shutter speeds are meaningful.
For example, the Q's electronic shutter reads the sensor one line at a time. It may spend 1/8000-th second on each line, but it takes 1/30-th second to read the entire sensor. Often you go with those high speeds because you're trying to "stop" some kind of motion, and this herky-jerky reading method can lead to a totally chaotic image, with the various pieces tossed all over the place.
I felt that my reply to you was completely clear.
I see little purpose to that kind of speed other than to stop motion (as I said then)
High-speed "electronic shutter" doesn't stop motion in a useful fashion (as I said then)
Therefore, I don't see any benefit to the high-speed "electronic shutter" apart from what the leaf-shutter can provide;
in other words, my personal opinion is that the high-speed "electronic shutter" does not make a difference (in the way I take pictures)
I am a software engineer by trade and I have worked with other engineers, scientists, and mathematicians.
In that setting "meaningful" implies "makes a difference".
I'm sorry if that wasn't clear to you.
