Canon 1D Mark IV ISO Tests. Un-boxing video.
Photographer John Deeb posted an un-boxing video of the new 1D Mark IV on engadget. The video, as always is pretty boring. However he was able to demonstrate the low light capabilities, with an ISO test from ISO 1600 to ISO 65,535.Â The camera did surprisingly well at ISO 25K. Yeah, thatâ€™s right I said ISO 25,000. I almost can’t believe it myself.
