BenQ DC C850 - Test shots - ISO performance

Review Price free/subscription

A range of test shots are shown over the next few pages. Here, the full size images at the minimum and maximum ISO settings have been reduced for bandwidth purposes to let you see the full image, and a series of crops taken from original full resolution images at a range of ISO settings have been included in order for you to gain an appreciation of the overall quality.


This is the full frame at the minimum ISO setting.


Even at 50 ISO there is some colour mottling visible in the darker areas, but the level of fine detail is pretty good.


Noise effects are slightly worse at 100 ISO.


At 200 ISO the noise reduction is blurring out the fine detail.


Worse still at 400 ISO.


Both noise effects and detail blurring at 800 ISO.


1600 ISO is unusable.


This is the full frame at the maximum ISO setting.

Many thanks Cliff for such a wonderful review. I must say everything you wrote is true. It's an excellent camera to make pictures for ebay. Also it makes nice video. I fell in love with Benq for it's monitor, mobile and c850. I wait on my toes to see your review of Benq e1260 or t1260.
