I would welcome any wide angle or teleconverter adapters for the gfx100rf (like for the x100vi). Sure, there might be image degradation, but in clutch moments, it can help capture a scene even if not at its best.

If I remember correctly X100 series was designed from the beginning to use the converters. Only real change was made in F (I think) when Fuji implemented an electronic connection between converter and camera. Optically nothing has changed. The old converters work also with the V and VI lens.

Since we have not heard anything from GFX100RF converters, I doubt there will be any. We have to do with a wider lens and cropping To my knowledge the camera also lacks the electronic connection and associated menu items.

, yes. The noise to signal ratio is high. I just try to tune out the most outspoken characters here who are very fond of self-identifying as experts.

Back to the GFX100RF, I have no doubt it will be a wonderful camera that will inspire photographers to actually make photographs, despite its (like every camera on the planet) limitations.

Lots of opinions, but who's to say anyone's wrong. Everyones use case is different.

I'd consider buying a TCL, depending on size and cost. Sure you can always crop. But as someone who dabbles in 1x1 TLR style street portraiture time to time, a 40mm equivalent TCL is attractive. I think the appeal of this should be clear to anyone who knows their medium format film history.

For those who make serious art of this and demand corner to corner premium quality, sure, this won't replace their X2D + XCD55 F2.5. But it's not supposed to. Or, if on a budget, this won't replace their GFX50R that I see some still using today (including with adapted classic manual focus lenses).

Or maybe it will, as who's to say they won't prefer a GFX100RF + TCL? Lots of factors go into the feeling of an image. I just know for a street portrait, I'm not all that fussed about the periphery of the frame if the subject and environment is conveyed with great effect.

Anyway, I'd be interested in a WCL for sure, as I sometimes do shoot 24mm for interior situations. Would also be nice for GFX-Pan. Besides the X-Pan 45mm, wasn't the G617 something like a 25mm equivalent?

If Fuji doesn't provide one, I hope a third-party Chinese manufacturer does. I just hope they're not overly ambitious and instead give us reasonably sized ones with good mid frame optical quality and modest conversion factors.

@robsonj@: there are teleconverters for the GR III/IIIx and to me they completly defy the purpose and point of the camera - being compact. I kind of feel the same way towards the 100RF in regards to those teleconverters. You have 20MP at 80mm eq. If you need a longer lens for your GFX the 100-200 exists. I hope they invest their ressources into a 100RF 50 f/3.2 instead of teleconverters. But that's just wishful thinking on my part.


20mp at 80mm isn’t enough if you like to use the xpan crop as I do

I've been able to get a landscape raw at f/8 into LR finally. It looks like the corners sharpen up nicely. It's probably fine wide open for street as well but I haven't really looked at wide open shots. Clearly getting the size down was a major priority for them and that's what makes it so different for a MF(or miniMF as it is really putting the mini into miniMF and people seem to like that ). I don't think there will be a problem with the glass.

Well I’m glad I was able to shift the convo on from ibis to teleconverters 😀. It is interesting to me that the hood connects via an adapter. Makes me think there are tcl, wcl plans. Either way I preordered anyway. I had the tcl for the x100, was only used very occasionally. For me, the compact rf and a wcl would be awesome for backpacking and the rf + tcl + wcl would be awesome for travel in general. But with neither, it would still be my go to for backpacking and travel.

Portability of the rf can’t be under estimated, when I travel home to England, the gfx generally stays at home, I take a m11 m11m and 4 primes all in a tiny think tank retrospective 5.

I find as I’ve grown older my focal length preferences have got wider and use of bokeh has reduced, maybe that’s just me being used to shooting on a real rangefinder where 28+35 and f5.6-8ish is a nice sweet spot for zone focusing 😀. And as for low light, I’m getting older, my bedtime is getting earlier anyway 🤣

I am not great fan of cropping to narrow field of view. Cropping to different aspect ratio is understandable. So is straightening a picture, even though one might loose plenty of resolution in the process.

Sure one can crop 100mp to 60mp, to make GFX100RF look like 35mm eqv, but after that degrading image quality starts to become obvious. That is me, your milage may vary. Ultimately it depends how one uses the picture. For social media or small print even extreme crop might be ok, although it kind of defeats the idea of having a hagh resolution camera.

I take GFX100RF as a quite limited machine - and that is why I consider it tempting. It is perfect for anybody looking for wide angle images with deep or hyperfocal DOF. Other than that better go with ILC GFX or Hasselblad. Or a high resolution full frame camera such as Sony A7rv. I must say I really like my A7rv. Sony lenses are the best in business (especially considering size) and the camera is real allrounder.

Counterpoint - the idea about having a high MP, fixed lens, compact camera is to be able to crop to your hearts desire. It makes the camera that much more usable for different scenarios and I feel like that's kind of the whole point of cameras like the 100RF or the Leica Q3 / 43. The larger the sensor and the more pixel, the better the resulting image quality of the crops. Leica Q3 and Q343 go even further than the 100RF offering even 5MP files at the longest "focal length". Remember that instagram is 1MP and most smartphones have a resolution lower than 3MP, where most of the images online ultimately get viewed on.

@robsonj If you need 50+MP at 80mm in 65x24 mode the 100RF is the wrong camera for you - look at the GFX then.

TINSTAAFL.
While I may crop in post, I never shoot while intending to crop. Cropping reduces DR; it is similar to shooting with a smaller sensor. If I shoot with Q or RF, I'd like to use the sensor to its full and frame accordingly.

Most scenes out there do not require the full dynamic range of the RF.

Especially if the main use is "story telling" ... a good story doesn't give a rat's backside about trivial technical differences and a great story can even survive totally trashed / junk technical matters.

Understanding the use case of "cropping" as an intentional part of the strategic EDC / compactness / simplicity ... means understanding that a decision was made to forego maximum technical capability, in exchange for a higher degree of deployment to immerse yourself into the story telling realm.

I was thinking about my Kodak DCS SLR/C ... it had no AA filter and back then folks were telling me all the problems with the moire issues and the lack of DR compared to some other rigs. Yet, those two issues never stopped me from getting my shots and really liking that camera (only real downside was one trick pony at base iso).


In the realm of quality / technical matters, folks have to take a step back and ask themselves if the level that the "issues" present keep them from achieving their goals to get the shot / tell the story. On a different realm, it also reminds me of the OM film system ... dang small lenses, but they vignette quite a bit. Backpackers, adventurers dug on it, vignetting be danged.

When we pit size vs. technical and maximum quality, it is ALWAYS, ALWAYS, ALWAYS going to have some form of quid pro quo issues for consideration. Should we consider to understand what / when / where / why / how those tradeoffs exist ... certainly. Does that fact that they exist mitigate its utility ... only to the degree that we allow it to thwart us.


I understand that I'm critically looking at it's native technical lens capabilities ... wrt distortion in particular. But, in the realm of understanding what it is / isn't, that gives me understanding for recognizing (and the accepting vs. rejecting) the attributes and determining how it fits my use case ... 100%, 99%, 50%, 2% ... and my tolerances for the gaps it might include.


Bottom line, if you truly want to tell the story, you aren't gonna give a rat's a$$ about how much DR reduction exists from a crop ... and let such trivial considerations interfere with your mindset for seeing the story. That's kinda the point of the camera is to relinquish your mind from a variety of trivial considerations (accepting their limitations and discarding your concerns of them), so you can get to the matter of the importance of the story, not the trivial bench jockey minutia.

I'm a techno junkie ... but, I'd like to still recognize the difference between when techno is important vs. when it is critical vs. when it is trivial ... and should be considered as an impediment / limitation vs. when it should be ignored as trivial minutia. Not saying I always get it right, nor figure it out as quickly as others ... but, yeah, there's a point when folks ( self included at times) can absolutely get lost in the forest of minutia, and can't find their way to a good photograph for stumbling over MTF and DR charts.

And, yes ... I'm talking to myself, too.

YMMV

I just downloaded some GFX100RF raw to check them (cropping included) in C1 that I normally use.

I must say vertically GFX files are huge. Horizontally not so. Horizontally there is a difference to Sony A7rv that I normally use, but in the end GFX image is only incrementally wider.

I must emphasize that Sony has recently put out some excellent lenses such as GM primes. Nothing wrong with GFX100RF lens, but I see nothing spectacular in it. Lens plays huge role in a high resolution camera, especially if cropping heavily. Additionally it seems that GFX100RF sunstars are a little meh. Obviously Fuji prioritized size (and cost) when designing the lens.

The fact that GFX100RF relies quite heavily on correcting barrel distortion in software is another implication of what were the priorities when designing the lens. Barrels distortion is about the same as in X100V with wide angle converter without software corrections.

How much would I crop GFX100RF? 35mm eqv sure, 50mm eqv in a pinch. To me 80mm eqv is a waste of a good medium format camera. m43 with a cheap 5mm/1.8 would be better at short telephoto field of view.

It is also important to note that when cropping one does not loose only pixels, also the overall rendering of the image is lost. When cropped the end result might be technically ok but it looks kind of flat and artificial.

Based on raw files I downloaded I think GFX100RF excels in colors and tonality, the usual Fujifilm hallmarks. Images take in hard sunlight look really good. Also the different aspect ratios seem to work well. I imagine that it is targeted to a photographer shooting "scapes" and casual photography in moderately wide lens. I belong to that group, although I am slightly annoyed by no IBIS and only f/4 max aperture.

As someone who always promotes the value of content and photographic vision over the pursuit of test-based technical record chasing, I’m somewhat sympathetic to your point of view.

However, in this case, a (the?) major point of using the larger 102MP sensor is ostensibly to achieve various kinds of technical image quality superiority over smaller formats.

You can “tell the story” effectively with a wide range of photographic equipment, including pretty much any Fujifilm camera, along with virtually any camera from the other manufacturers. If it is just a smaller, fixed lens camera that you want and the technical pluses aren’t so important after all…

The transition to teleconverters demonstrates that one camera can’t do everything. My last use of teleconverters was with my Yashica Mat 124G back in the seventies. It was a great option for film. Burdening a medium format sensor with lesser optics makes me question why someone would want this camera. The A7CR has some stellar small lenses available. The new Sigma 90mm is very small and provides resolution that isn’t far off medium format and it has great IBIS.

It also looks like Sony will, before the end of the year, be out with the A7Rvi and 80 MPix with 8+ stops of IBIS. This camera, will rival current Fujifilm and Hasselblad medium format. I suspect that this same sensor fab will be used on the next generation of medium format sensors to come..probably in 2026.

Had not heard that, but very interesting. I’ve been in “go slow mode” on plans for my next Big Camera system and have been since it became clear that Canon’s rumored plans for a high MP FF system in the lineage of the 5DsR seem to have evaporated.

A camera like the one you mention would likely trigger a switch for me.

Noise becomes more noticeable compared to the uncropped image when printed to the same size. Same reason DR increases with increasing sensor size given the same sensor design and pixel density, the noise/grain becomes smaller at the same print size.

Nothing changes at the pixel level obviously.
