Yes, it will. My camera is 4.2x2.4x1.3 inches (so just 0.1 in smaller on one dimension) and it fits in, so I'm sure yours will fit perfectly. Just use the exterior pocket for extra batteries instead of the interior sleeve.

Will NOT fit that camera. Listed dimensions for bag are in error. My Panasonic Lumix XS50 will not fit. It is a fairly small camera. Try to Lowepro Portland 20 (some extra space) or 30 (very generous too big?)

Do you know the measurements of your camera? (I checked...Nikon says 4.3 x 2.5 x 1.3) This case's main pocket is about 4.5 x 2.5 x 1.3...a tight fit, might be a pinch too small.

I checked the dimensions of your Powershot and yes it will indeed fit in the case. With room to spare. My camera also fits loosely in the case which I consider good because taking it out and putting it back in is very easy and quick. The case is very well-made and has plenty of protection for your camera.
