Fujifilm GFX100

For years, mirrorless cameras lagged behing DSLRs in terms of autofocus speed.

In order to catch up, companies started to incorporate phase detection pixels on their sensors, and modern cameras have phase detection pixels spread all over the sensors, very much to the delight of photographers, who enjoy fast autofoucs, eye autofocus all over the frame and reliable subject tracking.

But no technology is perfect, and so also phase detection has its downside.

When pushed to the extreme (meaning extreme shadow recovery for example), sensors with phase detection pixels can show some banding.

This has been documented with Nikon, Sony and so forth, and of course Fujifilm is no exception. They all use the same Sony sensor at the end of the day :).

It looks like also the Fujifilm GFX100 is (unsurprisingly) showing the same banding issue, when its RAW files are pushed to the extreme.

In fact, the Fujifilm GFX100 sensor has

  • a total of 3.78 million phase detection pixels
  • 7,776 PDAF pixels every 18 lines

The more phase detection pixels a sensor has, the more you can use phase detection also in lower light.

Bill Claff from Photons to Photos has published a Fujifilm GFX100 sensor heatmap (via dpreview), showing a short black line every 18 rows (see image above).

Should we panic?

I guess not. Or we could just throw any modern mirrorless camera into the garbage that uses phase detection pixels (unless it’s X-Trans ;) ).

It’s, as always, a tradeoff.

Do you want faster autofocus? Or do you want RAW files that even when pushed to its limits and beyond don’t show banding?

The Solution

First off: Fujifilm is fine tuning the firmware for the Fujifilm GFX100, and of course they are aware of banding. They are working to optimize sensor readout and the final firmware will show, how much banding the camera will really have.

But in any case, there is partially a solution to that, even without optimized and final firmware.

As I told you already months ago, Fujifilm is working to bring pixel shift multishot into the Fujifilm GFX100.

The original goal was to have it ready for GFX100 launch, but it needs a bit more time of development.

But pixel shift mulitshot will come, and as we have seen from other phase detection mirrorless cameras offering this feature, pixel shift reduces or even eliminates banding completely.

So, as long as you are shooting static subjects on a tripod and use pixel shift multishot, you won’t have any issues with banding.

Cambo Actus Fit for Fujifilm GFX100

In case you were wondering about Fujifilm GFX100 and Actus GFX, Cambo said on their facebook page:

“During the last couple of weeks we received a lot of emails regarding the Fuji GFX-100. Will it fit on the Actus-GFX? The answer is yes.

The new GFX is substantially higher than the current 50mp models. We’ve just machined the parts required to fit the 100mp body to the Actus. And as demo cameras are still sparse in Europe, we took the opportunity to try the combination during the grand opening of Calumet’s new store in Frankfurt.

Q: Does camera rotation clear for portrait orientation?
A: In portrait orientation you could actually use the Actus-GFX as it is. Only when used in landscape orientation the new GFX-100 requires more space.”

Hasselblad Teases New Camera Launch on June 19: 100 Megapixel Hasselblad X2D Coming to Compete with Fujifilm GFX100?

The timing could not have been better!

Fujifilm has just announced the Fujifilm GFX100 and is about to ship it on June 27, and now Hasselblad has published a teaser of what looks like the successor of the Hasselblad X1D.

Hasselblad says the launch will take place on June 19.

There are no further details. All we can see is an image showing a shutter button that looks just like the one of the Hasselblad X1D.

This indicates that the Hasselblad X2D (or Hasselblad X1D Mark II) could be on its way, maybe with the same 100 megapixel sensor of the Fujifilm GFX100.

And it would be high time, since the Hasselblad X1D is discontinued since a while now.

This is a fantastic news especially for Fujifilm GFX lovers, since the more competition there is in the medium format segment, the more companies will fight for customers and offer more features for less price.

So, dear Hasselblad, we all look forward to June 19!

Fujifilm GFX100 First Look: “Medium Format is Boss. All GF Lenses Need Firmware Update for Phase Detection AF Support”

Fujifilm GFX100

BHphoto went hands on with the Fujifilm GFX100. You can see their full video here.

  • no dials, feels like a camera of 2019
  • extreme cropping capability
  • autofocus feels like X-T3. Not that super fast, since it the AF motor has to move more glass inside GF lenses, but very very fast
  • all GF lenses need a firmware update to support phase detection AF
  • bigger glass is just a completely different look compared to full frame
  • vertical grip too sleek. Should be more rubberized and ergonomic
  • aimed at professionals and enthusiasts
  • for sports and wildlife there are higher frame rates options. But the GFX100 goes at 5fps
  • they tested the 5fps, and it hit every frame
  • video is a huge leap over what Fujifilm GFX50S and GFX50R can do
  • Medium Format is Boss! It’s ridiculous to compare it to full frame

Check out the full BHphoto GFX100 video here.

Fujifilm GFX100 Hands On Reviews

Matt Granger went hands on with the Fujifilm GFX100.

He starts by saying that he does not get any attention by Fujifilm, and was not invited to Japan for the launch. So he needed to wait for the Fujifilm GFX100 to be displayed at a photography fair, and all he could do is to talk to Fuji reps there and go only shortly hands on with the camera. So what he can share for now is only a quick first look.

Other major youtube channels also complaint about Fujifilm not flying them to exclusive events around the world (which is what Sony does all the time). If this is good or bad, I leave the judgement to you.

The Birth of the Fujifilm GFX100: Documenting 8 Months of Development Process (Part 1)

Fujifilm GFX100

For the last 8 months Fujifilm let Cinema5D closely monitor the birth of their new flagship large format sensor creation, the Fujifilm GFX 100.

Now they published their first video covering the birth of the Fujifilm GFX100. Part 2 will follow later and bring us inside the Fujifilm factory.

Here is what we learn, and at the bottom some screenshots from the video:

Photons to Photos: Fujifilm GFX100 Preliminary Dynamic Range and Other Sensor Measurements Results

Fujifilm GFX100 Sensor Data

Photons to Photos has released prelimiary Fujifilm GFX100 (non production) sensor measurement data.

In terms of dynamic range, the 100 megapixel GFX100 beats all full frame cameras. If you need even more dynamic range, you have to pay $40,000 for a Phase One.

The bump you see at ISO800 is due to dual conversion gain.

Earlier today we shared the DPReview lab shots, which in my eyes showed impressive results in favor of the Fujifilm GFX100.

DPReview: Fujifilm GFX100 Added to Studio Scene Test vs GFX50S, Sony a7rIII, Nikon Z7, Panasonic S1R

DPReview added the Fujifilm GFX100 to their studio scene comparison tool.

Compared to the Fujifilm GFX50S, the Fujifilm GFX100 shows noticably less moire, and it is also sharper than pretty much any other camera on the DPReview database. Regarding color noise at high ISO, the Fujifilm GFX100 is also superior to the GFX50S and any other full frame camera for that matter.

If you are into medium format GFX, then the GFX100 looks like a sensible step up in image quality.

You can download the RAW studio lab shots of DPR, and open them Adobe Lightroom and since today also at Capture One Pro 12.

And now, happy pixel peeping to all of you :)
