Canon 1D Mark IV - A hands on Review

[Sabyasachi Patra]

High ISO ability:
One of the features often talked about is the high ISO ability of the Mark IV. This camera has ISO 100 to ISO 12800 as standard ISOs. And then there are three further expandable high ISOs namely ISO 25600, ISO 51200 and ISO 102400. I had decided that I would be happy if I am able to shoot with ISO 3200 for critical moments, ISO 1600 very often and ISO 800 regularly. Let’s examine these three ISOs first. All the images have been processed in Lightroom 2.6 with default noise reduction. There are reports that DPP does a better job in processing the noise. However, Lightroom is my default software and I have evaluated it as I would use it. This image was created with a Canon EF 400mm f2.8 L IS USM lens plus EF 2xII converter, ISO 800, full frame image.
