Camerasize has added the Fujifilm GFX100RF to their database. Now you can compare its size to any other camera.

In our case we are going to compare the Fujifilm GFX10RF vs GFX50R vs X100VI vs Leica Q3 vs Sony RX1rII vs Hasselblad X2D.

Overall the Fujifilm GFX100RF is indeed very compact for sporting a sensor that is about 70% fuller than full frame.

I know some wish it would have a hybrid viewfinder, IBIS and a faster f/2 lens. But then, besides the much higher price, they’d probably hate the Fujifilm GFX100RF because it is too big to carry around for everyday shooting, which would be the biggest tradeoff of all.

A hybrid viewfinder would have been nice, but I am also fine with a huge and crisp top notch EVF (the GFX100RF has it) instead of a hybrid viewfinder.

And as Fujifilm explained here, the wide lens (plus almost vibration-free leaf shutter) actually allow to shoot at about 1/40th with sharp results. Not to talk of the terrific ISO performance of the GFX system, which also helps to keep shutter speeds higher. But for final judgment here I’ll wait some technical reviews about it. All I have seen demonstrating low shutter speed tests, is a launch video of Vistek (shared in our live blog), in which he showed samples at 1/30th and he was happy with the sharpness. I guess below that it will become harder to get very sharp results handheld.

But if that holds true, then it is indeed a tricky dilemma for Fujifilm: if images are still sharp at 1/30-1/40th of a second, is it still worth to trade off compactness and price for IBIS?

Out of curiosity I checked the shutter speed in my images of my last summer holiday (travels, landscape and city trips with family). When I shot handheld, I have found one image at 1/80th of a second (a picture of my son at sunset in Pienza, Tuscany). Then there are images I shot on tripod anyway because shutter speeds are so low that IBIS can’t help.

So I guess for my use case, IBIS would be nice to have, but the lack of it won’t have a terrible impact on my photography. In most of my images there are people in the frame (my kids, etc), so I can’t go too low with shutter speeds anyway.

One of the biggest critiques to the Fujifilm GFX100RF is the lack of IBIS, especially considering that it has a 100 megapixel medium format sensor.

So why has the Fujifilm GFX100RF no IBIS?

Well, that’s exactly what Thomas and Andreas asked the Japanese product managers of Fujifilm when they met them in Prague, who passed them the chart you can see above (video below).

Let’s take a look:

The important lines in the chart are the black diagonal lines. In that chart you can see that in order to get sharp images with for example a 250mm lens, you need to shoot at about 250th of a second.

On the very top (over the red line) we have the telephoto lenses that need OIS.

The purple on the left is the range where you need a tripod.

The yellow part shows where IBIS works best.

On the right we see the range that does not need IBIS and can be shot handheld without IBIS and yet get sharp images, and they marked the 35mmF4 in that range.

So, looking at the chart, I’d say that if you shoot at 1/40th of a second or higher, then IBIS would be of little use anyway.

And maybe in real world, you might be able to squeeze a bit more out of it. Test samples shared at the German fuji-x-forum.de look still sharp at 1/20th. So probably I personally would feel confident to go down to 1/30th, unless I am on my 7th coffee and my hands shake like crazy ;).

Also the leaf shutter helps to get sharper images, because it does not introduce as many vibrations as the mechanical shutter does.

One more tidbit about IBIS discussed in the video:

implementing IBIS would have made the camera bigger, but not that much.

Apparently the increase in body size would still be acceptable for Fujifilm. The problem would have been the lens, as in order to cover the entire sensor plus the area in which the sensor can move due to IBIS, the lens would have become significantly bigger. And since compactness was paramount for Fujifilm when developing the GFX100RF, they decided not to go with IBIS. The body size increase would have still been acceptable, but not the lens size.

And always keep in mind: whatever moves in your frame at very slow shutter speeds will get blurry anyway, as IBIS only compensate for camera shakes.
