How can I control the shutter speed on my d200?

You want the fastest shutter speed you can get and the largest aperture possible.
If you're close enough and it's allowed, use the flash. The flash will freeze the action. However, it's likely to give you a dark background instead of a blurry background.
If not, use the Aperture Priority mode. Open the lens to its maximum aperture (smallest f/number). This will give you the fastest shutter speed for the existing lighting conditions. The fast shutter speed will freeze the action and the large aperture will blur the background, though the amount of freezing may be limited if the lighting is relatively dark, as in a high school gym.
Be aware that if you're shooting indoors you're going up against the laws of physics. The human eye can adapt much better than any camera. A high school gym will appear light enough once you've been inside for a few minutes, but it is much, much darker than a bright day outdoors.

The ML-L3 does not work with the D200.
If you have a specific question about the D200's shutter release modes, please state it in a comment to this post.

If sent directly to Nikon, you should expect somewhere around $300 for a replacement shutter and will likely take 1-3 weeks.

are you using mirror lock-up or live-view feature?

Maje sure you lens it not set to manual focus and that the lens is mounted correctly. Also - FWIW - shoot with a fast shutter speed (1/250 or better) to avoid blur.

The flash is probably what's limiting your shutter speed. All cameras have a maximum shutter speed that syncronizes with the flash.

I have just the opposite problem I can't get more then 2 shots per shutter click in any mode in my D 200?

i could tell you how to fix it but it would probably cost more than a new camera. just buy a new one.

There's absolutely nothing wrong with your camera. You simply need to learn about the basics. Read on the web about exposure, shutter speed, aperture, and how they affect each other. If your shots are blurry, the reason is that the shutter speed was too low.

How can you know when the shutter speed is too low?

- Use a tripod (the VR of the lens must be off in this case)
- Or, for hand-held shots, use shutter priority mode and set a speed as fast as the focal length of the lens. - i.e. for focal length of 100mm, a handheld shot must be taken at 1/100 sec or faster. Of course, the light might not be available for such a faster speed. The VR also gives you some latitude, but it's not panacea.

Additionally, DSLR cameras (esp. if you shoot RAW) produce images that are less saturated and contrasty compared to the blown out photos produced by point and shoot cameras.

You have a remarkable camera, just take your time and learn the basics of photography.

what is the actual proablem?
