Is the 11-16mm lens on a Canon 7D equal to an 11mm lens or a cropped 17mm?

    I am looking at buying two camera bodies and want to get a nice wide lens.

    Currently I am considering a 5D MKII and a 7D, but I wonder if I should just buy 2x 7D's instead?

    I would like to use it for films but the stills are more useful to me to begin with, but the last thing I want is to have to buy two wide-angle lenses one for full-frame the other for cropped.

    I will need a wide lens for most of my work, but don't know if the Tokina 11mm-16mm is that on a cropped frame camera or if the lens is 11mm-16mm but equal to 17mm-24mm on an cropped frame.

    It's not easy to find this detail so any help and advice welcome.

    I realise I can't use it on the 5D without getting a crop, but advice is welcomed.

    Cheers, MP

    Also this lens will only work on a crop sensor,not on a full frame sensor :)

    Yes
    But if the 11-17 is EF-S only( even as Tokina) it wont work on a 5D

    Its not EF-S. Its still an EF mount. And as such will mount and fire on a 1Ds or 5D. Although it will vignette a lot!

    Its used a fair bit as a UWA on 1.3 crop 1DmkIII's etc.

    I've used my 10-20 on 5D too. Canon are the only company making ef-s lenses.


    But to answer the question yes the 11mm is a true 11mm like every SLR lens you have to apply the crop factor yourself, this is because the focal length is the focal length regardless of sensor size.

    Thanks
    I have the Tokina 12-24 and it is a non Canon therefore an EF but with warning to only use it on a Crop Sensor I assume this is because of the heavy Vignetting rather that a physical reason such as is the case with EF-S

    Correct. The vignette at 10mm is more like a holding a toilet role over the lens than a vignette :D
