Samsung ST70 Review

Image Quality


All of the sample images in this Review were taken using the 14 megapixel JPEG setting, which gives an average image size of around 3Mb.

Looking through a variety of our test images we noticed that the ST70 delivers good front to back of frame sharpness, though we did witness some occasional loss of definition when shooting at maximum wide angle, and disappointingly, some instances of lens flare when shooting in brighter conditions.

Other than that the camera delivered healthily warm yet still naturalistic skin tones, and colours in general are well rendered. In fact the ST70 delivers a better overall performance than we expected from a camera of its comparatively small size and low price, from which you'd usually expect (and steal yourself for) a slightly compromised performance.

Similarly, whilst by far from the worst low light performance we've seen, and a broader than expected light sensitivity range selectable from ISO 80 up to maximum ISO 3200, images do start to noticeably deteriorate and lose detail after ISO 800, noise and softness present in equal measure. That said, when selecting the 'night' option from among its pre-optimised selection of scene modes, we were pretty pleased with the end result - which is, as our test shots show, as good, if not better than the results from long-standing photographic brands in its class.

Overall another good showing from the plucky little Samsung.

Noise

There are 7 ISO settings available on the Samsung ST70. Here are some 100% crops which show the noise levels for each ISO setting:

ISO 80 (100% Crop)

ISO 100 (100% Crop)

   

ISO 200 (100% Crop)

ISO 400 (100% Crop)

   

ISO 800 (100% Crop)

ISO 1600 (100% Crop)

   

ISO 3200 (100% Crop)

 
 

Sharpening

Here are two 100% crops which have been Saved as Web - Quality 50 in Photoshop. The right-hand image has had some sharpening applied in Photoshop. The out-of-the camera images are a little soft at the default sharpening setting. You can change the in-camera sharpening level if you don't like the default look.

Chromatic Aberrations

The Samsung ST70 handled chromatic aberrations very well during the review, with limited purple fringing mainly present around the edges of objects in high-contrast situations, as shown in the examples below.

Example 1 (100% Crop)

Example 2 (100% Crop)

Macro

The Samsung ST70 offers a Macro setting that allows you to focus on a subject that is 10cms away from the camera when the lens is set to wide-angle. The first image shows how close you can get to the subject (in this case a compact flash card). The second image is a 100% crop.

Flash

The flash settings on the Samsung ST70 are Auto, Auto & Red-eye reduction, Fill-in flash, Slow sync, Flash off, and Red eye fix. These shots of a white coloured wall were taken at a distance of 1.5m.

Flash Off - Wide Angle (27mm)

Flash On - Wide Angle (27mm)

ISO 64 ISO 64
   

Flash Off - Telephoto (135mm)

Flash On - Telephoto (135mm)

ISO 64 ISO 64

And here are a couple of portrait shots. As you can see, neither the Auto setting or the Red Eye Fix option caused any amount of red-eye.

Night

The Samsung ST70's maximum shutter speed is 8 seconds in the Night Scene mode, which is good news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 4 seconds at ISO 80.
