Sony Cyber-shot DSC-T700 - 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.


This is the full frame at the minimum sensitivity setting of 80 ISO.


At the minimum ISO setting of 80 the image is mostly noise-free, but does look a bit over-processed.


Still no major noise problems at 100 ISO.


Colour saturation in the green channel is starting to fade at 200 ISO.


A sudden drop in image quality at 400 ISO, with very heavy noise reduction.


Even more noise at 800 ISO, with little fine detail remaining.


At 1600 ISO you can barely tell where the green of the car body ends and the black tyre begins.


3200 ISO, but the image quality sucks.


This is the full frame at the maximum sensitivity setting of 3200 ISO.

Hi there. Does the T700 suffer from the same 'harsh JPEG compression' that was written about the T77? If so, would a person that just uses a camera for holiday snaps and family shots (me!) really notice this? My latest camera was (until I broke it!) the Sony T9 and I was pretty happy with the image quality from that.

Thanks very much. Regards, Jim

Amazon currently have the T700 (in certain colours) for 𧶏: how does that affect the value score for this review and does it make it worth buying?

In general, the prices drop for everything we review, given enough time. This is why we clearly state Price As Reviewed (so you know what it was reviewed & scored against) but also the Latest Price for comparison.

Since Build Quality, Feature and Image Quality haven't changed with a lower price, they all stay as they are. 𧶏 is 㿗 less, or 17%. That would clearly improve the Value score from 4/10 but bear in mind the competition will also have dropped in price too probably.

Whether or not this would bump it from 7 Overall to an 8 is slightly moot - there are many models that scored 9 Overall at the time of review that might also have dropped in price over time :)
