Reason:
- I'm an event photographer looking for a second body and thinking of buying 7D (Don't want to swap lenses during an event)
- 35L on 7D isn't wide enough for me, but 24 will do the job.
- If need arises I can put 24LII on 5DIII and have more width to work with.
Do you guys think its a good idea?.. I haven't had any experience with 24LII, is it a good overall lens in terms of sharpness and other issues?

.. maybe it's a kind of religion ... but, in my case, for 30 years, since I got a A1+85L, every attempt I made to use zoom, I felt too much frustration as soon as light is a little bit weak (which means indoor, early morning, evening ans nights) impossible to freeze any moving subject !.
