So, not being an optical engineer, I feel that having a faster lens probably has some size compromises that would take away from a compact camera.

I would conjecture that they would probably have multiple engineering prototypes that they investigated. But that’s just a guess.

Going back to IBIS - for a successful system, the lens coverage has to be quite a bit larger than the sensor to be effective. So that’s probably why IBIS was not in the production model. I figured the lens would have to be larger, both the part inside the body as well as outside.

Those are

Like I said forget about IBS, that would make the camera and lens too big. But the difference between a f2.8 and f4 prime with todays tech and CAD would be interesting. I think we might even see it down the road in a GFX100R 🤷‍♂️

Me too. Out of all the videos on this camera I've seen, this is the one that makes me want one.

Too rich for my blood though (here it's 6,6k in USD). Maybe one day.

I feel like I would be in the target market, because the overall feature set, particularly the crop dial appeals to me. But the price is just too much for me, despite having a bit of spare cash. A $A 8500 camera with an f4 lens, which will struggle to get subject isolation, is just too expensive. If they made an APS-C version I'd probably bite.


That would be the X100VI.
But it’s impossible to get because of the back order situation.

While I appreciate that people have taken to it in droves sometimes as a fashion accessory, serious photographers like me have a hard time getting one.

But there’s something good that came out of it. I pre ordered the GFX100RF. I think that works really well as a two camera kit with my GFX100 S II.

And I agree, it’s pricy for a fixed lens compact, but so are some of the trips that I have taken.
So, putting it in that perspective, I decided to bite. As far as the price goes, I compare it to the price of he GFX100 SII body and that offers some comfort.

Still not an easy decision, but I think it might be exactly the smallish carry anywhere highly capable camera.

I still have my Panasonic GM, which is unbeatable in size for an interchangeable lens camera. I wish Panasonic would make a new version. I would have got that instead for the extreme portability and ability to change lenses. I consider m4/3 to be more than enough for an EDC camera.

Fuji is about to release a 23 pancake. It would be interesting to see if they scale that up for GFX, given that the 45/2.8 is way too big for what it gives you compared to smaller systems/lenses.

I think this article in petapixel covers all the thinking Fujifilm had to go through to come up with the GFX100RF.

It is similar to what we have speculated about their thought processes.

We should bookmark this article for rehash when the GFX100RFii comes out in 2029 with IBIS and is 3mm thicker and identical in all other ways

Maybe they will stabilize the entire sensor/shutter/lens as a unit, a merging of in-body and lens stabilization. That way the image circle doesn't change. But I agree, they will likely find a way given more time to work it out.

Interesting.

"There are three major “pain points” that photographers have immediately pointed out about the GFX100RF: no hybrid or optical viewfinder, the speed of the f/4 lens, and the lack of in-body image stabilization."

I don't think that the lack of an optical/hybrid viewfinder is really an issue for many people at this point. That was the case back with early mirrorless cameras that had big EVF issues and because photographers weren't that used to EVFs back then. Today the great majority of cameras come with EVFs now that DSLRs are fading to irrelevance.

I think there's room for disagreement about the f/4 lens. I get their point that in DOF terms it is arguably like a f/2.8 on full frame. (Not clear on their reference to two stops in the article.) Still, for the target market (street photography, travel) there are arguments that a somewhat larger f/2.8 aperture would have been desirable.

(I'm completely sure that almost everyone raving about the f/4 version of the camera would be raving about the f/2.8 version if the f/4 choice had never been in play... ;-) )

I'm not quite buying the IBIS exclusion explanation. I understand their point that it might not be quite as simple as just dropping the existing GFX IBIS system into the camera, though they clearly know how to make one without the ND (that they mention in the article) and how to do it in a miniMF sensor body. The sensor area/coverage issue was a choice — they prioritized making the camera a little bit smaller — and shortening the development cycle — over including IBIS. (And I agree with those who expect that a follow-up revision will have IBIS at some point.)

Dan, I do fine at F4 with the GFX 100 II and the wonderful GF 20-35 inside over 200 churches in the Med hand held at ISO 800 to 1600 at 1/15 second. How? 8 to 9 stops of IBIS. If you guys don't believe it, I have proof. Just glance through any one of my my Flickr albums the past 5 or 6 years.

So yes, the idea was to stay small w the RF so they blew off stabilization. Bad move in my opinion. My opinion is so strongly held that I'm not buying the camera, which will shock Fuji into some R&D.

For your case, shooting stationary subjects…yeh ibis would be great. For my case shooting subjects that move…not so much. Obviously this camera is not for you or others that need ibis…but there is so much more to photograph than motionless objects.

And, most times I shoot stationary subjects I use a tripod and my exposures can go into minutes.

I completely agree with your analysis, though interestingly enough, come out (respectfully) on the other side on the conclusions. Or at least on Fuji's side on two of them. We are all different and have different perspectives.

1. I can imagine the reasons for not doing an OVF, but I'm in the tiny minority that really wanted one. I'm not selling my M10-P and remain hopeful for a X-Pro 5 with 65:24 aspect ratio functionality. If this comes out, with an OVF for 18mm framelines and a rear LCD that lets me zone focus without opening the damn camera or raising it to my eye, my currently pre-ordered GFX100RF will almost assuredly go up for sale.

Of course, this will never come out, thus the pre-order.

2. My father, in his retirement, bought himself a X2D 100c + XCD55mm F2.5 V. The XCD V lenses already have an internal leaf shutter and rear lens elements millimeters away from the sensor. They are designed to balance compactness with optical quality.

But truthfully, I've never seriously considered buying a him XCD 38mm F2.5 V and borrowing his system from time to time. He's offered to -- and he'd love to do it. He wants to swap it for extended periods for my M10-P system. For some unfathomable reason he believes there's some Leica "magic".

We'll do the swap eventually, but truthfully, I have no interest, given the size of the XCD 2.5 V lenses, even the rather compact XCD 38mm F2.5 V. For all the awesomeness of the Hasselblad system, it's still not a casual EDC.

Also, his eyes are bad, and he can't use the rangefinder with his glasses anyway. His X2D LCD is better than my M10-P's live view, so I've been in no rush. Maybe, given his eyes, I should be.

I am sure the Fuji engineers could have improved on size had they made the GFX100RF a F2.8 or F3.0 lens. But it still would not be a casual daily carry for me. Double the light is double the light. You cannot defeat the laws of physics within the bounds of contemporaneous technology. Only make different compromises.

I'm sure they could reduce the total system size relative to the X2D + 38mm F2.5V. Maybe 15% - 20%? But it wouldn't be GFX100RF sized. It wouldn't be "keys, wallet, phone, X100V (or better yet, GRIII)" sized. This is obviously subjective.

3. I'm with you on IBIS, though I take Fuji at their word that they, today, they cannot, with commercially reasonable efforts, create an IBIS system that fits their design, price and release timing goals. Maybe I'm naive, but if I were a product manager, I would have pushed my team hard to put this feature in if they reasonably could.

It is a significant disadvantage from a marketing perspective given the X2D, Q3, X100VI, GRIII.

I'm sure they will work hard to make this change in the next 3 years.

With stabilization, that is certainly possible. I recently shared some handheld photographs on FM that I made inside churches in Nürnberg using a camera with IBIS and some fairly long exposures.

I think I wrote that there could be differences of opinion about the f/4 aperture, though it has certainly been raised as an issue by a lot of people, particularly in conjunction with the lack of IBIS. And while the smaller apertures work pretty will (again, in conjunction with IBIS) for subjects like these, I feel that f/2.8 would have been useful for people doing things like street photography, which seems to be one of the targets of the camera.

All aspects of camera design involve trade-offs and end up having both pluses and minuses. Here the question is how those pluses and minuses line up with the needs of the target market.

Your acknowledgement that you are “in the tiny minority that really wanted one“ is in line with my point that today the interest in the OVF has radically diminished for the reasons I mentioned in my post. It isn’t that no one is interested, just that the number is far smaller, and the willingness to go with an EVF is much greater.

I still believe that the hopes for a next-generation XPro that shares the hybrid viewfinder design with the previous models are unlikely to be satisfied. (I’ve written elsewhere about why I feel pretty strongly about this, so I won’t recount it all again here.) If there is something in the lineage of the XPro (and I’m not so sure there will be) then I think it is more likely something that I think of as a “Super X-E” with the rangefinder-style body, EVF-only, and full manual controls.

The x100v lacks the aspect ratio dial and the 65x24 crop, so its not quite the same. I'm aware of the work arounds. My X-T30ii with 27mm f2.8 or 18mm f2 is adequate for a small EDC. I'm thinking Fuji's business model is to push up the value chain, looking to make small production runs of unique cameras, which will allow them to sell all their production at high prices.

And, that lens will be significantly larger, probably bigger than the Q's Summilux, and not that far from Hassy's 55/2.5. I guess that would be almost on par with the Q3 43/2.


Personally, I don't find the f/4 that out of line for a "compact" MF.

I mean, historically MF glass is slower than FF glass. Historically, small lenses are slower than large lenses. The combination of MF and pancake small ... not sure what folks would otherwise expect from a MF pocket rocket. I mean, it looks smaller than the Hassy 45/4 P ... and certainly the body is smaller than the Hassy.

I'm not so sure that the lens design being so deeply recessed into the body doesn't influence the IBIS engineering decision, in part. I think that if they bring a GFX 100R (ILC vs. Fixed) to market, I think it would be a candidate for IBIS. But, since part of the optics are built "inside" the body ... IDK, could be an issue beyond what folks are thinking on the surface of traditional space requirements for (ILC) IBIS and lens design.
