Summary

Our Score:

7

User Score:

Over the next few pages we show a range of test shots. On this page the full size image at the minimum and maximum ISO settings have been reduced to let you see the full image, and a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality. These pictures were taken indoors using reflected natural light

----

This is the full frame at 100 ISO.

----

At 100 ISO the level of detail is good, but there is some unevenness of mid-tone colour.

----

Slightly more noise at 200 ISO, but overall quality is still fairly good.

----

At 400 ISO there is a speckling of noise across the whole image, and some detail is lost.

----

800 ISO and noise is now seriously hitting image quality.

----

1600 ISO is best avoided.

----

3200 ISO is available at 5MP. It would be OK for small web images.

----

At 6400 ISO the image quality is fairly terrible.

----

This is the full frame at 6400 ISO.

Please help me decide, I need before/after indoor room pictures for home staging, and all purpose for pleasure landscape, zoom, panorama and/or wide angle, burst are my features wanted. Decide between Pentax Optio P70, Pentax X70, Nikon NL100 or Canon IXUS110IS....havent used a camera in a long time. stabilization and indoor are concerns and for $100-$150 difference, I'd rather pay more for what I need rather than wishing Ii had bought something else later. Need soon. do I need anitreflective or glare coating? Which would be best/easiest but something to learn/grow with.

I don't understand this review.


Either the camera produces good photos or the "noise" spoils them.


Which is it?
