NEW Fuji GFX100S II vs Fuji GFX100 II - All you need to know

[@matthewbushey9455]

Love your detailed comparison! Great work, and thank you. Having used both of these cameras professionally, I can tell you that yes - you don’t get “$2.5k more image quality” out of the 100Sii . . . But the ergonomics of that camera, for longer professional shoots (especially shooting vertically), are awful. The deeper grip of the 100ii is immediately more comfortable; combined with the optional vertical grip and extra batteries, means a longer shoot is more comfortable on the hands - even with the added weight. Also, when shooting on media, faster CF-B cards in the 100ii rarely limit the buffer, offer faster downloads, are more rugged. I’ve never been so happy to leave fragile SD cards behind. While testing it, I bricked the 100Sii twice in professional use, where the camera literally overheated and prevented me from shooting any further until it cooled down . . . Shooting STILLS. 🤷🏻‍♂️ This would have been a disaster had I not had the 100ii on hand! I’ve certainly hit the buffer limit on the 100ii, but it’s never bricked me. The worst of both of these bodies is the abysmal shutter sync of 1/125s; I shouldn’t have to use HSS just to get 1/250s for professional flash photography. If Fuji would produce a few leaf shutter lenses, this would be tenable . . . But there’s already electronic shutter built in, so a faster sync speed is already doable. I really wish Fuji would make a specific edition of the GFX just for stills: strip out all the video functions, give us all the pro stills features, a super-fast sensor readout and chip set, refined ergo’s, and all the accessories Pro shooters need (and prosumers might enjoy). . . Please Fuji, pretty please?! 😉

Sounds like you need the X2D!

[@matthewbushey9455]

@@rayanayash as a pro Capture1 user, the X2D is meaningless piece of kit. The UI/UX is incredible, IQ and color is great, but the production workflow is a pain. It's also overpriced for what it is. IF the pricing were comparable to the GFX 100ii, I'd be far more tempted!

[@GH-gn6vu]

I agree with most of what you said and I'm very grateful for direct feedback on these models from a working professional. I think you're right that the ergonomic advantage of the non-S model is significant - especially if you shoot in portrait orientation a lot, and want to use a battery grip and the tilting EVF. Shooting from a position low to the ground, as I do sometimes for portraits with a different FF camera brand, a pivotable EVF would be a tremendous help (glare from the sky sometimes makes even a tilting rear screen of limited usefulness in outdoor shoots). I agree that there should be a better flash shutter sync speed. 1/125th is unambitious, even given the challenge presented by the large sensor size. It's been 1/125th since the first GFX came out in 2016 or 17. At that time, some full frame cameras (e.g. Sony A7Rii) had a real-world practical max shutter sync speed of 1/160th (Sony's specs for that model claimed 1/250th, but it was only 1/160th really in use - any higher and you'd get shadowing at the top of the frame)... so... okay... given the proportional size increase of the shutter, from full frame to GFX medium format... the step from 1/160th on FF to 1/125th on MF made sense and was arguably understandable at the time. But since then, most/all full frame cameras have a sync speed of 1/250th, and GFX has never improved since. Furthermore, one innovative full-frame model, trying hard to do everything possible with available technology, achieved 1/400th sync speed: the Sony A1. It achieved that by having a truly premium, super-quality mechanical shutter, first, which Fuji could do too given their expensive place in the market... and by combining it in a clever way with the high readout speed of a stacked sensor, to add more sync speed than the mechanical shutter could achieve on its own. Both techs, taken together, get you to 1/400th at full frame size. And such innovations at GFX size would enable a sync speed of 1/250th, as you requested, or maybe even 1/320th. And sure, okay, there is no stacked sensor available in GFX medium format size yet to help with this. But there will be, in time. And in the meantime, Fuji can at least seek to raise that mechanical-only shutter sync speed to be a more favourable fraction of the typical 1/250th best you see in the full-frame market if they really want to. These cameras are expensive enough to justify a premium, high-quality shutter. However I'm not sure I understand the wish, which I've seen expressed elsewhere too, for a dedicated stills camera instead of a camera that can also do video. I don't think there's any benefit or assistance for stills shooters from such a thing, whether from a functionality perspective or a purchasing price perspective. The things that make a modern mirrorless camera good for video aren't things that you can save money by stripping out. Where it's software functions (graphs, recording modes, etc)... the work programming that stuff is already done, and no money is saved by excluding them. Where it's hardware capabilities - sensor readout speeds, camera buffer size / internal processing power... the ability to constantly read the whole sensor all the time, whether to record the footage nonstop, or to interpret the image for stills and make focussing decisions... all of that is necessary, anyway, for a modern stills camera. Good autofocus requires a modern mirrorless camera to essentially be a video camera, behind the scenes - something that is always looking at the image, quickly, and doing number-crunching analysis and processing on it. Fuji's biggest failing is autofocus, and exactly this area is one which (among other things) needs more readout speed and processing speed - all of which is inseparable, dual-use technology for video recording as well. You need it anyway, so the video costs nothing and you save nothing from the purchasing price by excluding it on a product for sale.

[@matthewbushey9455]

@@GH-gn6vu Thanks much for your kudos of my observations. And I can't agree more - premium components, such as high-end shutter mechanisms, should be standard on a premium medium format body like GFX - and at least on the flagship models. You're completely right about higher sync speeds be easily achievable, and even necessary, given that these cameras in the Pro/Prosumer world are being used almost exclusively by landscape or portrait/fashion pro's. The added price is negligible, given the already costly (though reasonable) pricing of the system, and the lack of wider competition in the marketplace for cameras of this nature. But to your response about my waxing on regarding a stills-only camera: I have 2 distinctive personal reasons for a stills-only system . . . 1.) Internal and External Tech: yes, many of the systems that are already required to facilitate fast readout of the sensor carry over to video capabilities . . . BUT, not requiring 8K or 6K video readouts at the sensor level allows the electronics to be more properly tuned for stills - namely more highly specified and tuned chipsets, fast readout in the EVF (little-no blackout), and higher resolution EVF's and rear screens that don't have to be tuned to a video spec. Also, eliminating I/O (mic port, headphone port, full HDMI, etc) means more photo-based high-end I/O (TB3 or TB4 for tethering and power delivery), dual CFast-B slots, easier weatherproofing to a higher spec, fewer and simplified menus's, and focused controls/buttons/layout of the physical interactions with the body itself. Not only could these cameras then be faster at VERY specific photo-based tasks, including metering and faster AF (larger/better AF mechanisms), they would "excel" at one task (photo) - vs doing both (photo & video) "reasonably well." 2.) More Creative Focus: Fuji could leave the video in the mid-lower priced GFX models, and instead make the flagship body photo-only -- and when you strip away the video features, you're left with a purpose-built system that you KNOW only does one thing exceptionally well. The Psychology at first may seem trivial, but I notice that when I take out my LF 5x7 film camera, it feels refreshing to know that I'm just there to work thru a system of steps to insure one specific outcome . . . and not feel plagued (at times) by feeling like I might want some video, or spend too much time overthinking. If you must, you could squeeze a modern FF camera with decent video specs into any camera bag along with the GFX - even a recent iPhone with a good video app makes amazing files - so I relish knowing that my purpose-built camera is there to support one creative pursuit VERY well, and that Fuji didn't compromise by trying to make a camera mean everything to everyone. My use case in defending this scenario might be pretty individual, but last I checked, the new photo-only Hasselblad is doing quite well in sales - despite the price. Just my 2 cents. ;-)

[@mikearnspiger9715]

One of the best if not best explanations between the two bodies that I have seen...thank you for you thoroughness...

[@jonathanbush1936]

Excellent review, thank you for all the details you provided. As the current owner of the original GFX 50s and new GFX 100 II (and former owner of a 100s) I wanted to mention a couple of minor points. 1) In the differences between the terminals or ports on each camera in your comparison, you did not point out that the 100s II has a 2.5mm remote terminal on the grip side near the door for the SD cards. The 100 II, by comparison, and for a reason I still don’t understand, has a 3.5mm Mic/Remote port on the opposite side just above the HDMI port. I’ve had 3 GFX cameras and needed a different remote for each one. Fujifilm, please be more consistent (I, for one, prefer the remote location on the grip side). 2) In your description of the workings of the EVF tilt adapter the locking lever does not lock the adapter to the camera body. This lever, when unlocked, allows the adapter and mounted EVF to pivot left and right. When locked, the viewfinder will stay in whatever position you locked it in. So the tilt adapter allows left and right as well as up and down movement of the EVF. Only the two buttons on the side of the tilt adapter lock it to the body.

[@moskvin_net]

Thank you for the side-by-side comparison, that is very helpful. The two sensors are different. This is directly said by Fuji official people, no need to guess or reverse engineer )) I have to admit I had a strong prejudgment against the "HS" (100 II) version because of this recent trend across the brands to make higher-speed sensors sacrificing dynamic range. This trend is totally unacceptable for me, and I was seriously worry if I switch from my 6 y.old GFX 50S (the original version) to 100 II, will it be a de facto downgrade??? I noticed some opinions on the web that the HS sensor gives better results and could not believe it because of my a priori negative perception of that "high speed" trend. Bu! I do believe my eyes! In your comparison, actually there IS a difference, I can see it quite consistently as finer color nuances and "continuity" of the tone in the 100 II (yes, "HS"!) sensor. WOW! So, the 100 II seems to be the best of the two worlds, being both faster and with an edge in IQ. I think I am convinced )

[@drzman6901]

Great video. Thank you for your attention to detail. My quandary is that all of my photography is in the field. I photograph birds and often take hikes up to 5 miles with a camera on a neck strap plus a pair of binocs. Weight is important to me. Of course, I have to hold the camera as steady as possible for the shoot - no tripods. If I purchase either camera, I will buy the GF 500mm 5.6 lens. Currently, I have a 100-400mm Fuji zoom on an X-T5 body. If I go with the GFX 100S II the weight of camera and lens will be 2258g (883g+1375g). My current set up (X-T5+zoom) weighs in at 1932g. So, stepping up to the 100S means another 326g on my neck and if I go with the 100 II the weight increase over the X-T5 combination is 473g. From your video, I gather that the lower weight of the 100S will be more important to me than function gain I might obtain from the heavier 100 II. Does this sound reasonable?

[@EricGibaud]

I think both sensor are basically the same, but yes there is an extra layer for High Speed, my test show same colors, dynamic range. So if we speak about image quality, same results, if we speak about "action", less rolling shutter in video, more video shutter, autofocus yes, this one brings improvement. I reviewed both on my channel and actually bought the 100SII for myself. Great video, thank you.

I prefer the S100 ll because it is lighter and weather resistant, which is important to me. The 100ll weighs almost 2 kilograms with the 55 1.7. thanks for the detailed report.👍

This is something I was interested in going up to from 35mm in the past but the expense was difference was huge but now it looks like Fuji has bridged that gap now. Thank you for such a detailed video on these 2 cameras mate you definitely have given a decent review on the difference between these 2 models… id really love to see a panorama digital medium format camera but I’d be wishful thinking I’d say on looking for one 😂👍🏾😎

Great comparison! I’d love to see you do a video on your experiences using the GFX 100 II and the GF 35-70 while you were in Hong Kong.

[@dawster1949]

A super interesting video as always! I went for the 100 ii over the s ii despite the price difference (though here in the UK it’s £6,999 vs £4,999 and there was recently a £400 trade in bonus for the 100 ii which all makes the pricing closer). For me, the choice was really about all the extra functionality…those extra buttons on the 100 ii do make a difference. Also the design and amazing viewfinder. Although the 100 ii is larger, it fits in a bag better without the viewfinder, and can actually be more compact/discrete shooting this way on a tripod at night. My only complaint…at this price, it’s firmly in Leica/Hasselblad territory and the packaging experience is disappointing. Just a nice pouch to protect the viewfinder in my bag would have been nice! I’d be interested to hear your thoughts about that…

[@mathphotographer]

Thanks for sharing. And your comment is spot-on, Fuji could be a bit more generous with, e.g., some protection box for the removable EVF, etc. :)

the video specs bring it well above the Hasselblad, and a much more flexible and capable tool than the Leica in opinion.

Thank you for your usual excellent review, if I could add one point, the GFX 100II is a more rugged and weather sealed camera. The autofocus is also faster and more certain in my opinion. I have used it in very challenging weather conditions in a number of countries with no problems. If you are a professional who works like this, then the GFX100II is worth the extra money.

Thanks for your comment. I will consider to do some more camera comparisons going forward, seriously. If I could have only one camera it would be the Leica SL3 although this camera currently seems to have a firmware bug which will be fixed very soon by Leica. If I could carry in addition a backup camera it would be the Fuji GFX100II since then I have diversity in camera sensors. The Nikon Z8 and Z9 have the same sensor size as the Leica SL3 so would not be a complementary choice although excellent cameras :)

@@mathphotographer Very interesting choices. Imagine a scenario, where - 1. you are given a choice of having ONLY - all total of 3 cameras in as much portable form factor as possible for photography and cinematography. (can not be any fixed lens camera) 2. Any professional or personal or hobby work you do can only be limited to those 3 cameras and only you as one person shooter (which is why portable factor added). 3. No budget constraints One grand or hundred grand, don't matter. Also no limitations on lens just the body. 4. And one of the 3 cameras must be portable enough so it can be carried in backpack or as and EDC. What would you choose? You don't have to answer if you don't want. But I hope atleast you will make some videos based on these kind of concepts.

[@nevvanclarke9225]

I really don't think the read out speed is such an issue because it's not gonna be a sports camera even we're shooting portraits. You should maybe 15 or 20 frames in a quick burst but that's gonna be fine. I don't think having the HS is such a big deal to be quite honest? Generally GFX cameras are not used for sports you can shoot sports and wildlife with them but it's not they go. I don't see that as being a really big issue. I actually think the S model is the far better value camera? It's also smaller and significantly lighter and no one really does video on a GFX camera maybe a few people but that seems the better choice

[@colintraveller]

Budget wise it's half the price at Wex Camera unsure with other dealers ..

I agree with you. I do test rolling shutter effects with my camera and the GFX100II has significant rolling shutter so even if the readout time is faster than on the S-model it will not help in daily life :) For sports, I fully agree, I take Sony, Nikon or Canon cameras with full frame sensor.

I don’t think it’s fair to surmise the two sensors are different without knowing more information. The 100S II could have been software limited because of the choice to not include a CF express card slot. What is the max write speed of an SD card for 16bit uncompressed raw 102 megapixel images? How much heat would be generated transferring that much data? What is the pixel clock rate for both sensors? You need to dig more before making such a bold assumption.

[@mathphotographer]

@@jlehm Thanks for your comment. My assumption is based on the difference in the official Fuji specifications as shown on page 1 at specifications comparison in the video. The "HS" for the 100II versus no "HS" for the 100SII is a clear indication coming from the manufacturer. Image quality wise as said in the video I believe these sensors are at par :)

[@jlehm]

@@mathphotographer Fuji specifying one is high speed and the other is not does not directly mean that the hardware in the sensor is different though. It could be firmware.

[@mathphotographer]

@@jlehm Good point but I think (might be mistaken) that the readout time of a sensor is a hardware property. Its the physical limitation how fast the sensor readout line by line can be done. Its different of course if you have a global shutter which by now is only in a recent Sony Alpha camera implemented. I personally think Fuji should be more specific on readout times of their sensors since for the use of electronic shutter it makes a big difference what readout time is possible with a certain sensor. For my Hasselblad X2D for instance the electronic shutter is hardly usable because the readout time of the Hassy sensor is so slow that you get signfificant rolling shutter effects as soon as you have moving subjects in the scene. If that could be fixed by simple software/firmware, I am 100% sure Hasselblad would do it :)

[@VitVids]

Both cameras look so massive and kinda ugly especially if you compare them to Hasselblad.
