:rudolph: ... j'avais pas vu que ça avait zappé du EF au ZE ... que je ne connais pas du tout ...

mais chez kenrockwell .. il n'a pas l'air très convaincu par le zeiss (au moins en monture Nikon)..

"These Zeiss-branded lenses, at least the ones I've used in Nikon mount, are competent optically, but not better than Canon lenses, and real Canon lenses autofocus, weigh less, and have much better manual focus feel than the ZF Nikon-mount versions of these lenses. I doubt the Canon-mount variants will be any different, and I'll let you know when I get to try these in person."
