Oui Fredo. Et pour finir j'ajouterai que pour qui ceux souhaiteraient utiliser un Zeiss ZE sur un Canon 1D, Zeiss préconise ceci :

For the camera models Canon EOS 1Ds MkIII, EOS 1D MkIII, EOS 1D, EOS 1DS, EOS 1DS MKII, EOS 1 MK II, EOS 1V, EOS 1, EOS 1N HS, EOS RS and EOS 3 we do recommend type EC-A (with micro prism ring) or EC-B (incl. split-image indicator) which are offered by the manufacturer and can also be purchased at specialty retailer stores.
