I've seen several requests around the web for info on using a grip strap the the CoolPix 990. The CoolPix has a strap tunnel that presents a challenge for mounting a strap, but I've worked out an easy way to do the trick.
I hope the illustration above is clear enough. I apologize for not showing the strap attached to the camera, but I'll have to shoot that using 35mm later on. The nylon cable tie loop is inserted to run through the strap tunnel and the "head" of the tie keeps it from pulling through. If you don't have a cable tie, use some nylon cord tied in a loop and use the knot to prevent prevent the loop from pulling through.
I use the Zing Action Strap. Op/Tech also makes a neoprene grip strap and both can be found for about $20 US. Nikon also makes a grip strap, but it's significantly more expensive.
Please let me know if you have questions. I know some folks have started using cat/dog collars for CP990 straps, but I think this will be much more comfortable and secure.
There are dealer links at these sites, but I'd look for these at B&W, Adorama and Focus Camera.
As long as your home made attachment point is secure, the strap will stay attached to the camera. The OpTech strap fits more like a glove and would be more secure, if that's a concern. I just use the strap to provide a little more support when shooting, especially since a neck strap gets in the way for waist level shots.
BJ It looks like the zing strap is only meant for using the view finder. I have gotten into the habit of taking most shots with the LCD (excpt for sunny/bright days). Which strap is better for that use? thanks bob
I leave my grip strap on all the time. However, I don't stroll around with my Coolpix when shooting (my film SLRs serve that roll). I primarily use the LCD too, and the grip strap provides some extra security for both LCD and viewfinder viewing.
I put this together because I was reading about folks using puppy collars and the like to rig their own grip straps. Nikon's is very expensive. The Zing is priced reasonable, it's comfortable, and you can hang the camera from your wrist using the elastic strap as well as the neoprene part.
