As someone who shoots on Fujifilm (XT-3), this was an intensely fascinating read. Thanks, now I have half a mind to sit down and re-implement this code, just to get a feel of how it works.




I've been thinking of buying that camera for a while, do you recommend it? Do you have anything to say that will finally push me over the edge to actually but it?

You can get the X-T4 relatively cheaply. Unlike the T3, it has a fully articulated screen and in-body image stabilization.

I have the X-T4 and X-E3, both of which purchased used for much below the price of the newest models (about $800 each). No regrets, and I love both equally.

The E3 is my stripped-down pocketable camera; with the Fuji 27mm pancake lens, I can fit it in a jacket pocket or shoulder strap bag, and it weighs almost nothing, less than my iPhone. This combo is pretty much equivalent to the immensely popular X100IV, but much better value for money.

The T4 is the bigger camera I use for nature and macro shooting. Tons of settings, more advanced features (focus bracketing and "picture in picture" focus closeup are important to me), more advanced dials. It's heavier and bulkier, but also more solid (IBIS, weather sealing).

For some reason Fuji appears to consider yellow focus peaking (which IMHO is the best colourbfor it) to be a high-end feature reserved for the T4, which is annoying.


Why yellow and not red? I find red much easier to see. Also I tend to agree about the X-E line but it’s been refreshing to use the X100IV with the inbuilt ND filter and not worry about changing lenses.

I don't know, but I recommend trying it, you might be surprised.

The X100IV is awesome, of course, and if I could afford it, I'd probably own one. But it's more than 2x what I paid for my X-E3.

A fixed-lens camera is built around the limitation of having just that lens. To me, if I only bring the 27mm with me when shooting, then that is exactly like a fixed-lens camera. But it also means I have the option to take it on a bird-watching trip using my Fujifilm 70-300mm lens — something you just wouldn't be able to do with an X100. That flexibility is worth something, which in my opinion makes the lower price of the X-E range even more of a bargain compared to the X100.


Will give it a shot!

Definitely agree with you, I think if Fuji made the X-E range contain an ND filter, then it would be the ultimate every day camera. Whilst the 27mm F2 on the X100IV is nice, being able to go to an even lower aperture can be priceless in some situations.


I recently upgraded from an XT-3 to an XT-5, but loved my XT-3 and would still recommend it as a good purchase if you can find a decent deal on one in good condition. Fuji’s AF is not the best in the business, so I wouldn’t recommend one if you’re planning on using it for e.g. sports photography, but apart from that the XT series has no real downsides. The physical dials for ISO+exposure+shutter speed are fantastic and Fuji’s color processing makes images that I just enjoy looking at, even if they’re not as strictly neutral and accurate as what you’d get from someone else.

Fujifilm's whole X-mount series is wonderful and while I shoot "full-frame" M mount to remain interoperable between digital and film, there is no doubt in my mind that I would have a Fujifilm X-mount series if I only shot digital based on how much fun they have been when I have borrowed/tested them. Great "enthusiast level" cameras, great glass, solid build, everything has a button/dial, does not break the bank, and I actually know more than one professional photographer that shoots them and one of them even shooting sports!

I have an XT-1 from 2015 (still working!) and recently started considering upgrading to an XT-5 but I'm a little hesitant to buy a "new" camera first released in 2023 that still retails for almost the same price as two years ago. I'm so torn between just going for it and waiting (who knows how long) for the X-T6 to come out. Perhaps I should just try to find a good deal on an X-T4.

Innovation is very slow in photography world these days, X-T5 made a big jump in MP count compared to X-T4, but resolution aside image quality is pretty much the same, and other improvements were marginal.

I still use X-T2, and it has not really aged, even when compared to my X100V. Infamous Fuji AF is where they progress slowly but steadily, so that's the primary feature that I'd look into when choosing between generations.


If it helps, I pay reasonably close attention to Fuji rumors because I'm deep in the ecosystem, and at present there appears to be no indication that an XT-6 is coming any time soon. They just released the GFX100RF and XE-5, plus there are rumors of an X-T30 III soon, and with all that in the pipeline I doubt they are also finishing up an XT-6. The -4 and -5 are still great cameras, I would just go for whichever of those you think is a better deal.

> an XT-6 is coming any time soon

Besides, it's still near impossible to get an X100 VI. B&H's backlog must be over a year at this point.


See the trick is not to buy it new!

The X-T4 is fantastic. See my other comment in this thread.

The "new release premium" is just too high, in my opinion. Cameras aren't getting better so fast that you aren't better off with the previous model.


I have the same one and I can definitely recommend it. It depends what your camera experience is, but if you have had one that collected dust on a shelf in the past, I can guarantee you that this one is more fun to use and has a much lower risk of dust collection

Apologies, didn't check HN for a while. I recommend it if you can get it around ~500-ish USD. I paid $750 (for the body) + $150 (for a 23mmF2 lens) in Jul 2024 used with a bunch of accessories including 4 batteries.

The biggest annoyance I've found is the horrendous battery life on the X-T3. For a long day outside on a trip, I end up going through at least 3 batteries.

The XT-4 is identical to the X-T3 (well, more so than any other x-tn -> x-t(n+1) camera) but fixes a few of the flaws in the X-T3 with massively improved battery life + IBIS which I'd recommend just because a lot of acclaimed lenses these days forgo OIS (ref: many Sigmas for instance), which could be worth it over the long term.

If you are very price sensitive then the X-T3 is still a really good purchase, with nifty features like dual SD slots which make it great to have backups/RAW+JPEG on two cards. Compared to an average photo from a phone, there just isn't much computationally going on in mirrorless cameras so even an x-t1 would be a good purchase.

If you want to shoot photos for the experience rather than getting clinically perfect images, and do not want absolute performance wrt focusing etc., it's definitely at the top IMO; analog with every control having a dedicated physical control (ISO, Shutter Speed and Exposure Compensation and aperture on Fuji lenses). I love it because it's the equivalent of driving an air-cooled Porsche, warts and all.


I have an X-T3 and I love it. I went from an X-E2, to a Sony set up, and then quickly went back to Fuji. There's just something about Fuji that made it more enjoyable to shoot, for me (mostly travel photos).

I will say the only thing that gives me FOMO is the lack of the Classic Negative film sim, as a lot of recipes that I see online that I really like uses that film sim as the base.

If what appeals to you about Fuji's are the recipes and film sims, I'd make sure to research which ones you like, and then work out which model has the film sim you need to recreate it.


Another happy X-T3 owner here (I had in my hand a Nikon D40X, D300s, D810 before getting a X-T1 and then upgrading to X-T3 ; thanks dad).

Yes, this is a very good camera. I love UI of Fujifilm cameras; and by that I do not mean the menu system (which is... serviceable) but the physical dial for each of the main setting. Putting them in "A" for automatic just make sense compared to the usual PSAM modes.


I own 4 Fujifilm cameras and personally, I'd recommend being VERY careful and thinking hard about this purchase. This isn't the same Fujifilm as it used to be. The company was once known for its "Kaizen" approach, which has long since disappeared. Prices are now inflated because they're riding on popularity. Autofocus in Fuji is simply weak.

The question is whether you actually need such a camera for anything. With a new smartphone that has multiple lenses, out-of-the-box photos will turn out MUCH NICER than from a camera, because initial processing is built into the software. Digital cameras don't have this. You need to take RAW and work pretty hard on it to make the photo look as good as what a smartphone delivers right away.

In tourist destinations, you can often find middle-aged guys running around with huge cameras when in reality most of their photos are quite poor. Because they don't realize that with a regular phone, their pictures would be much nicer.

You’re completely neglecting to highlight Fuji’s film simulations. I use Fuji’s specifically because they produce excellent jpgs out of camera. Not really sure where your take is coming from, an xt3 on auto will blow any smartphone picture FAR out of the water.


For those who love the Fuji film simulation looks but can't or don't want to buy an overpriced-because-influencers camera, there are now apps that do great Fuji’s film simulation: https://apps.apple.com/us/app/rni-films-photo-raw-editor/id1...

This is not true. Yes, these are characteristic color grading profiles, but if you want your photo to actually look proper, you still need to process the RAW file and you can add the Fujifilm profile as an extra on top of that.

There's NOTHING special about these profiles. It's a matter of taste. If you're buying a mirrorless camera, it means you have ambitions to take photos at a reasonably high level. Nobody who wants to be at a high level will shoot JPGs.


It’s true that phones cameras are miracles of technology, especially considering their size. But I take a modern Fuji traveling because the modern phone camera look is so over-processed and distinct. There’s no faking the real optics a large aperture and sensor gives, the portrait mode on phones is still a poor imitation of the real thing.

Fuji then has the whole film simulation system with all their colour science from the last century. It’s a ton of fun, and the jpgs it produces are distinct and beautiful, and I believe better than 99% of people could achieve from post processing the raws, myself included.

The middle-age guy part is accurate though, I got it as a thirtieth present.


I don’t find this at all, even compared to my (now rather old) X-T1.

For quick shots to remember an event or night out, modern phone cameras are fine.

For anything that I’d call photography and actually want to print, display, etc. I rarely if ever get results I’m really happy with from a phone camera.

If you’re in any way interested in photography beyond taking a few snaps at parties and on holidays, I highly recommend getting a real camera. I’ve found the Fuji system to be great, from the lenses to the out of camera JPEGs and film simulations that mean you can pretty much avoid doing any significant editing or post-processing if, like me, you find that all quite tedious.


Yes, if someone's goal is to learn photography and they're also interested in it from a technical point of view, then these are definitely cameras worth considering. My main point is that if someone just wants to "take nice photos" they should seriously think about whether to buy a good phone instead.

This aligns with my experience as well. The bigger sensor does generate pictures that look more crisp in big prints or zoomed in. In theory it should gather more light, but in reality, phones stitch together multiple exposures, and frequently produce nicer low light images without much noise. For sharing on social media, it's hard to notice a difference. For me its event worse with the x100 since the wide lens doesn't have that signature compression and depth of field, so the photos don't really stand out that much, no wonder most x100 photographers rely on color filters (film sims) and high contrast to draw attention.

I know of no phone camera that can produce the portraits of an X100s 23mm lens at f/2.

Here you're talking about shallow depth of field which is desirable for portraits. But show me a camera that will have in JPG the dynamic range that you have in a smartphone by default? Show me a camera that will have as LARGE depth of field as smartphones have thanks to their small sensor.

These are all pros and cons depending on the scenario, but a phone has one advantage - it's small and you have it always with you.


Not sure what you mean by produce, it depends on lighting and photographer skill. Not like the 23mm is really a portrait lens either and f/2 isn't spectacular.

Gonna be honest: if you have to frequently use RAW to make Fuji photos look good, it may be a skill issue.

Wrong. If you have to frequently use film simulations to make camera photos look good, it may be a skill issue.

This comment exhibits the normal sort of hideous gatekeeping attitude that is common in photography.

Even if phone cameras were twice as good, for me its simply more fun to take pictures with my camera.
