    You can use both the 1.4x and 2.0x TCs on the 100-400 lens but obviously there is a hit to aperture. The 100-400 with the 2.0TC at 400 becomes an 800mm lens but at that spec its f11.
    There are no third party native X mount telephotos your only non Fuji option is a lens with an adapter which means manual focus manual aperture and of course no stabilisation if the lens had it otherwise.

    Most 2x TCs do have some softening effect. You need to work out whether the result is acceptable to you.

    There's very little impact on the image quality with most 1.4x Converters in my experience. Obviously you do lose a stop of light but that's pretty much it and so it's a decent compromise. With a 2x you lose two stops and have a definite impact on IQ. So personally I'd stick with the 1.4x. But that does get you to the angle of view of an 840mm on Full Frame. It's pretty rare to get anything with a narrower aov than that. Even with this angle of view the types of images you can take in the real world are probably limited. The angle is so limited it's very tricky to find your subject unless it isn't moving.

    When I need a super telephoto lens for my Fuji X body, I add an X-mount adapter to a 500mm or 1000mm Nikon lens.

    How much of a super tele do you need?

    Are you sure?

    At 30 metres away a 1200mm Full Frame would fill the frame with something only 90cm wide. On (say) a Nikon full frame camera I can't think of many modern lenses that go more than 800mm and then you're talking VERY expensive (eg £5000 for a Sigma and £15,000 for the Nikkor itself)

    Nikon and Canon make a 600mm f/4 that is used successfully by many wildlife photographers.

    If you really can afford a $10000 lens then don't put it on a Fuji but pay a little more for a D500 or similar. It doesn't make much sense to use such a lens a manual lens with Fuji.

    I agree!

    However, it meets the criteria of the original poster.

    That's certainly true. I wonder, though, how often most people would actually be able to use the super telephotos? Leaving cost entirely to one side (!!!) - the 600mm f4 weighs 3.8kg and is 43cm long. The 800mm f5.6 weighs 4.6kg and is 46cm long. I'm sure both are fantastic lenses - and I certainly wouldn't object if somebody gifted me either - but many people consider the Fuji 100-400 to be pretty hefty and that's 1.4kg and 21cm long.

    For a professional Wildlife Photographer (especially of birds) I can certainly see how the Nikkors make sense. But I'm much less sure how often most of us would actually be able to use either except in our imaginations!

    And on top of that 4.6kg (and another kilo for the camera) what about the tripod you'll need most of the time.
    Oh, and better hope for a clear day and no heat convection currents.
    I admire those who can get good results with 600 on full frame never mind 1200 on aps-c

    Should 2xTC be 2 stops? 1.4xTC is 1 stop so f5.6 would be f8.

    If thinking manual there is canon 400mm f5.6 prime. One of the best for the price with image and AF comparable to canon superteles. Not sure how well it works in manual AF on Fuji. But used it is $800 or so now a days.
