    Canon / Sigma 400 zoom

    Canon 100-400 L IS and Sigma EX 80-400 IS, two consecutive years at le Mans.
    Perhaps not fair as the Sigma is on the 20D and Canon on the 1DmkIIN

    The tighter, bottom one is the Sigma? Looks sharper to me. What are the exposure settings?

    Sorry John, can't remember, they're in the EXIF but PR isn't showing the images for me to check. I think the lack of sharpness with the Canon is my fault.

    I checked the EXIF and saw that the settings were very different. How's the auto focus on the Sigma? Is the continuous focus speed and accuracy ok?

    Sigma AF speed was the reason I replaced it the week after Le Mans with the Canon.
    It didn't cope at Goodwood Festival of Speed where I was closer to the cars.
    Fine on people in the top paddock though.
