There are workarounds, if you choose to go that route.

    Have you ever added the minimum length extensiopn tube to a 17-55mm lens and placed it on a FF?


    I have, and, on my 5D MK II, I can focus out to about 12 inches. Thats really useful advice for someone who is trying to learn.

    No, but that's because I choose to use the equipment as Canon intends it to be used. People who are 'trying to learn' should probably not be trying to mount EF-S lenses on incompatible bodies without the requisite knowledge.


    In any case, the point of this thread was about compatibility and 'crop factors', not to complain about design decisions made by Canon.
