One Of These Lenses Is Not Like The Others
Okay, see if you can figure it out. You'll need to be in a darkened theatre to discover the difference - come and buy all these three lenses from us and explore the mystery. I'll give you some clues.
1. It ain't the aperture. They are all about f:1.4 or f:1.5 so they work good in the dark.
2. It ain't the lens mount - these cameras can all be put to work on a Fujifilm X-E2 camera - the Fuji mounts straight off and the Leica or Zeiss lenses can go on the the Fujifilm adapter.
3. It ain't the autofocus. The lenses can all be manually focussed with the Fujifilm X-E2 and the focus peaking and enlarged central image you get by pressing the control wheel make the things go into focus very precisely.
4. It ain't the lens performance. They ALL perform brilliantly. I can't see as good as they can.
5. It ain't the chrome on the Zeiss - you can get this same lens in black.
6. It ain't the focal length. They are all normal lenses as far as the APS-C sensor goes.
Okay? Give up?
It's the little raised blue plastic dot on the Zeiss and the little red plastic dot on the Leica. There is no raised dot on the Fujifilm - just a painted red stripe. It helps you orientate the lens for mounting...but not in a darkened theatre when you can't see it.
You fumble, turn to whatever light you can find, and finally pull out a pocket torch to see what you are doing.
Okay - time to rethink, Fujifilm. Put a raised dot or some other tactile aid for lens changing in the dark. When my lenses pass through their warranty period and can be legitimately attacked with a fire axe, I shall ask Ernest to attach some form of dot for me - so I am not fumbling in the dark.
I do that enough when it comes to politics and finances...
