I'm not much of a lens person myself Jordy, so all those acronyms I can't help you with. The only difference I myself can make out is that the first is a faster lens because the aperture stops down all the way to 2.8...while the Carl Zeiss is 3.5. , but I'm sure you knew that already! I'm sure Rork would no a thing or two about these...he seems to really be a lens junkie!

I am, therefore I create.......
