Nikon Coolpix S9100 - ISO Test Shots

By Gavin Stocker



Our Score:


The Nikon Coolpix S9100 offers a light sensitivity range starting out at a user selectable ISO160 and topping out at ISO3200. We also get both Auto ISO and a user selectable fixed ISO range setting, so users can limit how high the camera automatically 'strays' to preserve picture quality. Let's see how the S9100 gets on with our standard test set up, shot using a tripod, available light at the highest JPEG resolution and utilising auto white balance.

ISO 160

The lowest setting on the S9100 is ISO160, coincidentally also the option the camera itself chose when we tried both its Auto ISO and the Fixed Range ISO settings. As we'd expect there's no noise visible anywhere in the image

ISO 200

Up a notch at ISO200 and all is still well with the S9100's performance; again no image noise to report

ISO 400

We're at ISO400, the setting at which noise begins to creep into shadow areas on lesser compacts. But again we have a clean bill of health from the S9100. If we scrutinise the image very closely it's marginally softer than at ISO200

ISO 800

At ISO800 there's a subtle softening of overall detail which has again kept any instance of image noise at bay - but this really is nit picking as viewing the full frame you'd be hard pressed to notice any difference at all between this and the lower settings

ISO 1600

At ISO1600 shadow detail is beginning to take on a speckled appearance - but only if you're really looking closely

ISO 3200

The top setting of ISO3200 and there's a more obvious smoothing effect as well as a slight colour shift compared with the previous images. Overall though the S9100 has delivered a very respectable ISO performance for a sub £300 camera.

Thanks for the review, I have been trying to decide between the Nikon S9100, Sony DSC-HX9V & Fuji FinePix F550 EXR. I look forward to your reviews of the other higher-end compacts before I make a choice!

Nice comment Nic...lol.
As for the camera- looks great,high iso noise levels look very acceptable indeed. Such a shame there's no aperture/shutter priority modes.... :o(
That alone makes it a non starter for me.... shame.. :o(

I bought this camera...... twice. And had to return it both times - so now I've ended up with the Sony DSC-HX9V.

The camera itself was great for me - but the first one I bought, the lens kept sticking and eventually wouldn't return to it's casing at all. The second one I bought also had a problem with the lens - the automatic cover kept sticking either coming out or going in making the camera completely useless.

Very disappointing - so I didn't want to risk getting a third one.

So is the Sony DSC HX9 V or Nikon S9100 the winner?

If you are after a point and shoot camera with an excellent 18 x zoom this is without doubt the best camera on the market at £131 it's a no brainer.Yes the Sony may well have more features but remeber it is well over £100 in price. Takes very good pictures and very easy to use my only gripe is when the camera is zoomed right out the you do have to hold the camera very still or the pics can be a little blurry. Best little camera I have bought and would recommend To anyone.
