Converters: What's the difference between the two Lamy converters?
It's not enough that Lamy has their own proprietary ink cartridge converter....they have two different ones:
So what's the difference? Well, the Z24 (red one) only fits the Al-Star, Joy, Nexx, Safari, and Vista. The Z26 (black one) fits all these as well, though it is the only one that can be used in the Accent, CP1, Dialog 3, Logo, Pur, Scala, and Studio.
None of this really matters too much, after all. The pens that require the Z26 all come with one already, so it's only relevant if you need a replacement. And the pens that don't come with converters (Safari/Vista/Al-Star) can accept either version. The Z26 costs a few cents more, not enough to really matter too much. What does matter is if you wanted to have a slicker-looking Vista (the clear pen), the Z26 just looks a little snazzier than the Z24, in my opinion.
