I have a Nikon D3100, even at shutter speed of 1/200, it feels like the shutter is set at 1/8. I takes shots like it was set at 1/200 but the shutter seems slow and very loud.

What could be the issue?

The pictures seem like they have a low shutter speed, or the sound is the problem?

The mirror flapping around probably takes around 1/8 of a second and makes much more noise than the shutter.

The photos will be different, but the shutter sound, sounds the same. It seems like it takes the same amount of time to take each photo.

I suspect that a lot of the sound is due to moving the mirror up and down. The D3100 can only take images at 3fps. It is only when you get into shutter times of more than 3/10 sec that the time to take the image is longer than the 'mechanics' of the camera taking the picture. Or look at it another way if you take picutres at 1/1000 and 1/10 the camera still can only take three per second.

All the best

I'm guessing you are hearing the mirror flip not the shutter. Also be advised the way the shutter works is it doesn't fully open when you get above (I believe 1/200th) but it just opens a slit. This is why when you force the camera to go above a certain shutter speed and use a flash you get these black bars, those are the shutter curtains.

I hope that made sense. I know what I'm trying to say but I've been up for about 36 hours so it may not have come out right.
