Twenty-eight lenses were nominated for inclusion in the poll, which in itself speaks for the strength of the Canon lens line-up, I believe.
This poll is purely subjective - the aim is to see if the community has a consensus view on which are the true gems among current Canon lenses, the ones where most people would nod their head if someone said "That's a great lens!", even if it is not perfect.
The criteria are for you, the voter to decide. They could include speed, precision and accuracy of focus, focal length range, build quality, IS, field flatness, value for money, weight, invariant maximum aperture, chromatic aberration, ... well - anything you like, really. Weight these as you see fit, and try to narrow it down to the single lens that is "best overall".
If you can't do that because you think several lenses really warrant the distinction, that's OK too. If I do it right, you should be able to vote for multiple lenses from the list, but bear in mind that voting for all of them would have the same effect on the outcome as not voting at all, so please be a little selective.
This is a secret ballot; your choices will not be displayed, although of course, you are free to discuss them in the thread.
Thanks for the nominations: let the voting commence.
