Lens Recommendation to mimic P900/1000 Functionality?

[Luna_Tick]

I'm getting a Fujifilm for its overall quality, but I want the zoom functionality of a p950 / p1000. What lens(es) do you recommend with the xt4 to achieve p1000 abilities (at the very minimum).

On the long end, the p1000 is a 3000 mm FF equivalent.

Longest native lens is the 100-400 mm. Couple it with the TC 2x you get 800mm, so 1200 mm FF equivalent. 

You'd get much higher quality than the pxx00 with that combination but far from the focal length.

You will never get such a versatile zoom range in one (or even 2) lense(s) on the Fuji system.

@flamidey Thanks! What are your thoughts on using the Canon EF 800mm with a Fuji camera? Strange that there are no competitors to the Nikon ultra zooms (which are so Amazing for astronomy, actually). I was hoping there would be a Fuji-compatible DIY solution that beats the p1000/p900 in all areas (of performance/quality).

Missed your reply, sorry.

You will probably have a hell of a time focusing at 800mm unless it's a completely static subject or using very high aperture numbers.

The 800 will only give you 1200mm equivalent anyway, so off by a wide margin.

If you're going for astro at 3000mm, you are going to need a 2000$ mount and you won't be able to see anything because you'd be at f11+ equivalent (except for moon).

For the moon, you will get the same or better results with the 400 + 1.4x than with the p1000. The p1000 has a 1/2.3" sensor. That's 13 times smaller surface, which means you can crop a lot from the APS-C of the Fuji and get equivalent results.

You will probably need some kind of stabilization, either a very good tripod or a stabilized lens (like the Fuji 100-400)...
