Canon 1D MKIV New ISO performance images by Jeff Ascough


Jeff Ascough is UK based photographer that is known for not using flash for any of his shoots. Looks like he’s been using 1-series bodies for quite awhile and really familiar with them. Looks like Jeff has the camera 24hrs before his shoots and didn’t have alot of time setting up the camera, but its not much different from his 1DsMKIII. Shots from the Canon 1DMKIV they are stunning in low light!
Autofocus performance is stunning. There is no other word for it. Canon have spent a lot of time and energy on this aspect of the camera and it shows. I was shooting in horrific lighting for AF systems, and it just performed faultlessly. I used the center point and the back button for focusing as this is what I have become use to over the past 12 months with the 5DMKII, and like I said it was faultless. I didn’t try AI servo mode (as I always use One shot) or any of the other AF options (some of which have been borrowed from the 7D). Source:[Jeff Ascough/Canonrumors]
