I have a pair of X-T30-II's as they are light and dependable. I mainly use fixed focal length lenses, the more compact Fujifilm ones. However, for longer reach I have been using the 100-400 Fujifilm zoom. Yes, it is not the lightest but it is quite well made and works well for me, even though I don't like zooms very much. I picked mine up from a reputable e-bay seller,, and it works fine. The lens stabilization works well even though the body doesn't have IBIS. I'm not entirely sure what the "Pro" designation on some of the lenses Fujifilm makes as plenty of my compact fixed focal lengths don't have it on them and they are superb pieces of glass. Frankly, if it works for you I'd just ignore the "marketing" labels.
Now 400 mm doesn't seem like it has that much reach, but remember this will be the equivalent of 600 mm for a full frame digital or 35 mm film camera. 10 years ago, unless you were a professional photographer hiring obscenely expensive lenses, 600 mm was a very long lens for anyone to own. That is a lot of reach. Anything more than that is going to be substantially larger, probably heavier and with less light transmission, oh and very much more expensive.
I like the 100-400 mm a lot, especially for the money, and it gives me very reasonable results. I'd take mine with me on a safari any day. I think you will be able to keep far enough away from the big kitties to stay safe. I use mine with a mono-pod quite often, and with the lens stabilization is turned off.

I took all my Nikon AI-S FF and AF DX lenses and mounted them via adapters on my 26MP Fuji sensors. They seemed fine to me. I did the same with my Olympus Zuiko lenses and they also seemed fine. The ones I was worried about were the Nikon DX lenses as I was using them for D200 10MP cameras. But, with the exception of the Zuiko 70-140 F4 zoom, they all seemed fine to me. Some of the older lenses had inferior coatings so you had to be more cautious about flair but I couldn't see any real inferiority to be honest.
Now for the Nikon 28mm F/2.8 AF-D, to be fair, released around 1994/1995, it was not of very good optical quality on either Nikon FX or DX cameras at the time. It appeared inferior when I tried it, against my 35mm AI-S F/2.8 on a D200, and that 35mm f/2.8 was not that brilliant a lens either, so I didn't buy it. At the time the lens was considered worse than either the earlier 28 AI-S or even the then contemporary 28-70mm zoom. If I recall it was based on a 6 element design derived from the E series lens, of which the 28mm E series was not Nikon's finest. So to me this would have been a case of a not terribly good lens in the first place, not being very good on a 40MP sensor. I'm sure it would have been passable on the 6MP sensor, but it wasn't very good on the 10MP D200 DX one. I'm sure it was getting noticeably bad on the 16MP sensor, even worse on the 26MP one, so by the time it comes to 40MP it's probably truly awful.
However, if you look at the quality of most of the current and recent Fujifilm lenses, they are generally starting at a much higher quality baseline, so I still think jumping from 26MP to 40MP is not going to make them look significantly inferior. OK, some might look better wide open than others if pixel peeping, but I personally wouldn't bother rushing out to replace anything Fujifilm that I think looks good on the 26MP sensors on a 40MP one. Other brands, especially third party ones, might be a bit iffy, but the Fujifilm glass in general is pretty good at 26MP and therefore I think will handle 40MP without too much trouble.
I'll guess I'll see if and when I get a Fujifilm 40MP body whether this holds up, but I'm not going to not buy a Fujifilm lens that's not on "the list" in the meantime ,for fear it is going to look bad on the 40MP sensor in the future.

In the end I bought a second X-T30-II body. I like the way they operate, I'm not so keen on the PASM dial style operation. I tried the X-T3 and X-T4 but I still preferred the size of the X-T30-II. I don't miss the IBIS with the primes up to 50mm. I don't shoot video anyways.
I also bought a few Olympus OM Zuiko to X-Mount manual adapters and I've been playing with a variety of Zuiko lenses in manual mode from my old OM-2 cameras. The Zuiko lenses are all later multi-coated versions and produce decent results, especially the 50mm f/1.8.
So, I'm happy with my choice and the Fujifilm gear as a whole so far.

No, not advertising, just thinking aloud. It helps sometimes to get your head around things.
I just like the feel of the X-T30-II to be honest. It';s nice and compact and feels metallic with the compact primes on it. I put a thumb rest mounted from the hot shoe on it and that helps me carry it around, and from not activating the Q button all the time. I wish the flash cover was not plastic, but other than that it seems to have a quality feel to my mind. I also figure I can buy quite a bit of glass with the difference in price over the very awesome, I must admit, X-H2.
Thanks for the input, I appreciate it.

Well, I'm Martin, having emigrated from the UK 33 years ago. I live in the great state of Utah. I am just switching from Nikon gear to Fujifilm.
