Howdy everyone. Considering a wider angle lens for my 500cm, I have a project coming up and believe a wider angle FOV would be appropriate. Can anyone give me any feedback on their experience with eh Zeiss System 40mm? Actually probably any of the 40mm lenses would do but almost all mine so far are CF *T so I thought I'd stick with that- any commentary on any version of this lens is welcome tho. Thanks, as always, for indulging me!
