Pentax X70 Digital Camera - Test Shots - ISO Performance

By Cliff Smith



Our 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?
