How Sony Is Rewriting Dynamic Range Sensor Performance (DGO vs DCG) — And the Hidden Drawbacks You Need to Know

Dual Conversion Gain (DCG) – The “Old” Tech

First things first: what exactly is Dual Conversion Gain?
Modern camera sensors — Fujifilm included — operate in two modes:

  • Low conversion gain: used at lower ISO values
  • High conversion gain: activated automatically at higher ISO values (for example, ISO 500 on the GFX100 II)

Let’s look at the Fujifilm GFX100 II dynamic range data using Photons to Photos data:

  • ISO 400 → 10.49 stops DR
  • ISO 500 → 10.91 stops DR
  • ISO 640 → 10.62 stops DR

Why does dynamic range increase at ISO 500 and ISO 640 compared to ISO 400?

Because that’s the point where the camera switches into high-gain mode, which reduces read noise and produces a DR “bump.”

For years, this dual conversion gain jump was the key method to maximize sensor performance.

But that changed—recently, and dramatically—with the launch of the Panasonic S1II first, and now also with the Sony A7V.

Dual Gain Output (DGO) – The New Tech

With the Panasonic S1 II (Sony-made, partially stacked sensor) and now the Sony A7 V, something unusual appeared in the data:

Fujifilm Holiday Savings: What Deals Expire December 28 vs. What Lasts Until January 18

Most of the Fujifilm deals are running well into the new year and will officially end on January 18.

However, there is one exception you should be aware of: the $200 price drop on the Fujifilm X half is only available until December 28.

10 Fujifilm Cameras Meet for Thanksgiving Dinner and This is What Happened Next

Thanksgiving is here, and while most families argue over who burned the stuffing, we in the Fujifilm community know the real drama happens when our cameras show up to dinner. If each Fujifilm camera were a guest, here’s what they’d bring to the table — literally.

X-T5
Arrives with a fully homemade meal, proudly reminding everyone that every single step was done manually — even the gravy. Keeps adjusting the dinner table “for composition”.

GFX100S II
Brings a turkey so gigantic the table collapses. Says it’s “just a casual medium-format bird”. Everyone pretends they’re not intimidated.

X-Pro3
Brings a gourmet dish but serves it face-down, so nobody can actually see it. “Stop chimping through the dishes. Focus on the Thanksgiving experience first, not the results” it insists, refusing to flip the plate over. Spends the whole evening fully present and savoring every moment.

X-S20
Shows up quietly with store-bought mashed potatoes, super humble, not bragging about anything. Yet all the other cameras side-eye it because it secretly carries features no one else has — like that fully automatic subject-detection mode that does all the work while pretending it’s “nothing special.

X-E5
Arrives with a small, perfectly curated dish — nothing fancy, but stylish enough that everyone compliments it. Quietly slips into a seat, looking effortlessly cool without even trying.

X-M5
Shows up with a perfectly plated appetizer, but keeps looking around the table like it’s lost. No EVF to guide it, so it improvises — and somehow, every shot still turns out amazing anyway.

X70
Shows up quietly without being invited… mostly because everyone forgot it even existed. Brings a tiny but absolutely delicious dish that makes everyone wonder, “Wait, why did Fujifilm never make another one of you?” Then it slips away before anyone can ask for the recipe.

X-H2S
Arrives with a towering trifle that’s already collapsing, fruit spilling everywhere, and layers sliding off the plate. Immediately realizes it’s still running last year’s flawed firmware, apologizes to the group, and rushes off to the kitchen to install the update — promising to return once everything is perfectly stabilized — it’s still there, struggling to connect to the smartphone app to finally install the update.

X100VI
Was supposed to bring artisanal cranberry sauce, but got kidnapped by scalpers as soon as it left home. Never made it to the dinner, leaving everyone scrolling online, refreshing for a glimpse of it. It was later spotted on eBay, held hostage with a wildly overpriced ransom for release.

X-T6
And then, totally surprising to anyone, a guest from the future shows up of nowhere: the Fujifilm X-T6! It brings a futuristic dish nobody’s ever seen before, full of features and flavors that blow everyone’s mind. The other fellow cameras on the table are curious, asks questions. The Fujifilm X-T6 just whispers something about having a new heart and brain, about firmware improvements, about features no other camera has ever heard of before. It ends up saying “everything will change” and then vanishes before anyone can ask more questions. Only left a note behind: read FujiRumors.com, and you’ll know soon enough ;).

The End

That’s my way to wish you all a wonderful Thanksgiving.

And feel free to let more cameras join the dinner in the comments down below. Other brands are welcome too :).

Fujifilm X-T6 Coming Second Half 2026 – And What About X-Pro4, X-H3/S, X-T60, X-S30 and Rest of 6th-Gen Wave?

I shared the rumor that the Fujifilm X-T6 will come in the second half of 2026.

Now, many have been skeptical and said this can’t be possible.

Why?

Because, if we look at the refresh rate of…

… we can see that even taking the historic slowest refresh rate for X-T* cameras, we should have gotten an X-T6 in August 2025 already.

Hence, a Fujifilm X-T6 release in the second half of 2026 would be extraodrinarily, almost impossibly, slow.

But… and this is what I forgot to tell you in my previous article… this information comes from trusted sources. So I can only confirm what I wrote already.

And now I need to answer the question that inevitably popped-up: what about the Fujifilm X-Pro4, Fujifilm X-H3, Fujifilm X-H3S, Fujifilm X-S30, Fujifilm X-T60, Fujifilm X-E6, Fujifilm GFX100 III and the rest of the 6th generation cameras?

So here is where I have to be very clear – and you should read carefully:

I do not know if the Fujifilm X-T6 will be the first camera to feature the 6th generation platform or if there will be other 6th gen. cameras coming maybe in the first half of 2026.

I will try my best to find the answer for you… but it certainly would help if somebody could drop me hint, 100% anonymously via rumor box or Signal chat, or via email at fujirumor@gmail.com or personal message on social media.

I’ve Traveled the World with Fujifilm’s ‘Worst’ Lens and I Loved it – The Only Flaw, and the One (Fujifilm-Teased) Lens That Could Replace It

I have recently asked you what you consider the best and worst Fujifilm related gear announced in 2025 (third party AF lenses included).

Well, a fellow Fujifilm X-H group member declared here the XF18-135mm as the worst announcement.

Now, besides the fact that the Fujinon XF18-135mm was announced in mid 2014, hence it was not really part of our big survey, I thought it was an interesting comment and that maybe it was time to talk a bit about this lens.

A lens I own by the way, and that made me sell these two lenses for it.

Now, as we said, the Fujinon XF18-135mm was announced in 2014, hence at a time when the Fujifilm X system was relatively new on the market.

So while it is reasonably to expect that the most modern Fujinon lenses perform better than those launched 11 or 12 years ago, I’d dare to say that anyway the Fujinon XF18-135mm is actually a pretty decent performer. I’d say an even very good performer for what it is.

The true problem of the lens is another one: I think it is the one Fujinon lens that suffers most from sample variation, meaning you might get an excellent copy — or a noticeably weaker one — simply due to manufacturing tolerances.

While Fujifilm has drastically improved this aspect of manufacturing over the years, at the time the XF18-135mm was released — and particularly with that lens — sample variation was a real concern for early buyers.

This explains why some are very happy with this lens (for example me), while others are not.

In my case, here are some pictures I took with it:

As you can see, the Fujinon XF18-135mm has been a loyal companion to me for over a decade. It has traveled with me all over the world, and I’ve always appreciated both its flexibility and its image quality.

That said, I probably ended up with a particularly good copy.

So if you’re thinking of buying one — especially second-hand — I’d definitely recommend trying it first and taking a few test shots.

But with that said, for every person who had a less-than-ideal experience with this lens, there are many more who genuinely appreciate it.

In fact, the Fujinon XF18-135mm was even used to shoot the official stills for the blockbuster Dunkirk.

And we have had some interviews with fellow X shooters, who declared it their favorite lens:

So I call myself a very happy Fujinon XF18-135mm owner.

But if I had to pick — or better, nitpick — one aspect that occasionally bothered me just a little, it would be the range. If only it were a touch wider on the short end, and offered just a bit more reach on the long end, it would come very close to perfection.

In short: make it a true, awesome superzoom!

And you know what?

Fujifilm has already revealed the estimated main specs and size of exactly such a lens in their “10 lenses under consideration” survey.

And here on FujiRumors we already made a specs and side-by-side size comparison between the XF16-200mm and XF18-135mm.

If Fujifilm manages to keep the XF16-200mm on the smaller and lighter side of their current estimates, then that might be the one lens capable of replacing my XF18-135mm.

But until that day comes — if it ever does — I’ll proudly call myself a very happy XF18-135mm owner.

If this lens is good enough to shoot professional stills on the set of a multi-million-dollar blockbuster, then it’s certainly good enough for my far more humble needs and modest skills.

There’s just one important note: especially if you’re buying an older, second-hand copy, make sure to test it first. No other Fujinon lens is known to exhibit sample variation quite as strongly as the XF18-135mm.
