Fujifilm GFX100 Development Story with GF Lenses Autofocus Speed Ranking

Fujifilm GFX100

Fujifilm has published a first Fujifilm GFX100 development story article.

They start with discussing the definition of the sensor, medium format or large format.

There is not much point in having a discussion as to how to call the format of 44 x 33mm. We tend to seek for the historical ground from the days of silver halide film; 6 x 4.5 is medium format, and 4 x 5 inch or larger is large format, but the explanation does not have any suggestion other than historical legitimacy.

in terms of resolution, the current 44 x 33mm format surpasses that of the 6 x 4.5 and even the 8 x 10. There still is the unique color reproduction of the silver halide films, but if the medium and the large format is designed for large prints, then there is no point in seeking historical ground to call what format GFX is. Because with the GFX100, we can have the prints even larger.

The core part of the article is the comparison between Fujifilm GFX100 and GFX50 in terms of AF speed.

The major change from X-Pro1 to X-Pro2 was the installation of phase detection AF. The same goes for the GFX100 when compared to the change from GFX 50S / 50R. Furthermore, the AF algorithm of the GFX100 is same as that of the X-T3, meaning not only is it fast, but is now also tougher against in low light conditions, high frequency subjects and low contrast subjects.

To put simply, the GFX100 has the agility like the X-T3 and achieves the descriptive power like the 8×10. There have never been a system like this before. This is a whole new experience.

The lenses, that have the biggest benefit in terms of AF speed thanks to the phase detection AF pixels on the GFX100 are the GF63mm and GF45mm.

GF lenses autofocus speed on GFX100 (with latest GF lens firmware udpate):

  • GF 23mmF4 R LM WR – 0,140 sec
  • GF 45mmF2.8 R WR – 0,183 sec
  • GF 63mmF2.8 R WR – 0,186 sec
  • GF 110mmF2 R LM WR – 0,208 sec
  • GF 120mmF4 R LM OIS WR Macro – 0,181 sec
  • GF 250mmF4 R LM OIS WR – 0,212 sec
  • GF 32-64mmF4 R LM WR – 0,168 sec

Fujifilm Manager About Fujifilm GFX100 Pixel Shift Multishot, Full Frame Crop Mode with Faster Sensor Readout and More

A new edition of the Medium Format Magazine has just been released.

It’s packed with content of great contributors, like Jonas Rask, Ming Thein, Take Kayo and more.

This edition includes also an interview with Makoto Oishi, product planner for Fujifilm GFX100.

In this article I will highlight a few things the manager said about the Fujifilm GFX100. But there is definitely a lot more to read at the Medium Format Magazine.

If pixel shift multishot will come to the Fujifilm GFX100 will depend on customer demand

The manager bluffs. They know customers want it, and they are already working on it, as FujiRumors reported exclusively here.

They asked Makoto Oishi if there will be a “full-frame crop mode” with faster sensor readout for even faster AF, higher EVF refresh rates, higher burst rates and shorter blackout times. The manager diplomatically says:

We can’t answer. It’s confidential information.

No comment by the manager also when asked about the Fujifilm GFX50R and 50S successors.

This and more can be read at the Medium Format Magazine, that goes well beyond the interview with the manager.

Fujifilm GFX100: One Last Roundup Before Shipping Starts

Fujifilm GFX100

The Fujifilm GFX100 is about to ship, and what we have for you is one last glorious Fujifilm GFX100 roundup, before it starts falling into hands of mere mortals (with pockets a bit bigger than mere mortals ;) ).

The Slanted Lens tested the Fujifilm GFX100. Problem? They didn’t use the latest firmware that adds support for phase detection AF on GF lenses, and Lightroom still officially marks the GFX100 as preliminary supported. Sadly this makes every review so far incomplete.

With that said, here is what they think about the GFX100 (video below).

  • details are amazing
  • in medium format at f/2 you have so just very little DOF
  • dynamic range test
  • at -5 EV he is still able to recover the hightlights with no problem
  • he thinks it could have been underexposed for at least two more stops, and he’d be able to recover that
  • at +1EV he is able to hold the highlights, with just a little bit pink color shift
  • at +2EV the highlights are gone, with yellow color shift
  • at +3EV the details are gone, skin tones are yellow
  • at +4EV it’s basically blown out. No way to recover that image
  • if you work in very contrasty situations, this camera will work extremely well, because of amazing shadow recovery
  • pretty amazing dynamic range
  • ISO test
  • ISO 100 very clean
  • ISO 200 there is a little bit of grain
  • ISO 400 also a little bit of grain
  • ISO 800 grain builds up more
  • ISO 3200 grain starts to become very pronounced
  • ISO 6400 major grain. He thinks it’s unusable for stills
  • ISO 12,800 becomes pixelized
  • ISO 256,000 grain is extremely strong
  • He’d not go over ISO 400 for clean images in stills and in general up to 1600. For video up to 3200
  • even at higher ISO, the colors remain consistent, no shift
  • Autofocus
  • in stills he is not as impressed as he hoped for [I noticed when the subject was far away, the tracking was not so reliable, but more close, super sharp. I personally wonder about his AF settings. Also, pre-production, you know :)]
  • in video holds the focus well on the subject, and AF is as good as anything else on the market
  • IBIS
  • Impressive. Might be a great camera to put on a drone

Let’s Get Serious: Hasselblad X1D II 50C not a Fujifilm GFX 50 Killer, and GFX100 vs X1DII with 3 Lenses Cost the Same

So, Hasselblad did it, and they announced the brand new Hasselblad X1D II 50C.

It comes with a good price tag of $5,750.

That’s still more expensive than the Fujifilm GFX50R and Fujifilm GFX50S, but not that much. And it is certainly much cheaper than the Fujifilm GFX100, but the latter features a 100 MP BSI sensor and IBIS.

I am very happy that Hasselblad is going aggressive when it comes to pricing on the Hasselblad X1D II 50C.

But from here to say that the Hasselblad X1D II 50C is a Fujifilm GFX killer (as some said over at facebook and elsewhere) is a bit an exaggeration.

Usually, when you buy a camera, you also buy some lenses to go with it. And you always have to factor lenses into your investment, too.

So let’s do it now:

Let’s buy the Hasselblad X1D II 50C as well as the GFX 50R with 3 comparable GF and X1D lenses (not counting the current GFX discount).

with

with

with

The Fujifilm GFX kit will cost you $10,896, whereas the Hasselblad X1D kit $ 17,425.

You basically save about 40% by investing into the GFX system, and if you would buy today, with the current GFX deals, you actually save almost 50% over the X1D system.

And what about the Fujifilm GFX100?

Let’s try the same combo:

  • GFX 100 + 3 lenses above = $ 16,396
  • X1D II 50C + 3 lenses above = $ 17,425

So even by buying the Fujifilm GFX100 and 3 lenses at full price, you still save $1,000 with the Fuji GFX system and you also get:

  • IBIS
  • much faster autofocus
  • 100 megapixel
  • 4K/30p video
  • twice as fast continuous shooting frame rate
  • BSI sensor with full phase detection pixel coverage
  • & more

There is one fundamental design choice Hasselblad made, that makes the X1D system always substantially more expensive over the GFX system: the lack of focal plane shutter.

This has 2 downsides:

  • you can’t use cheap old legacy glass on the Hasselblad X1D
  • you have to pay for the leaf shutter every single time with every lens purchase

Guys, I am the first one to be happy about another player in the medium format market, that competes with Fujifilm. That’s what we customers need: competition!

The Hasselblad X1D II 50C is a much needed and welcome upgrade to the orginial X1D. The faster processor will sort out quite some issues the first generation cameras had.

But the GFX system remains the by far most affordable option to go into medium format, and the new Hasselblad X1D II 50C hasn’t changed that.

DPReview Admits Flawed Fujifilm GFX100 Studio Test Shots and Says They Will Re-Shoot it

Earlier this month, we shared the news about the GFX100 studio test scene at DPReview.

While the images turned out sharper than the competition, some were hoping for an even better performance.

Well, turns out DPReview studio test shots were flawed. In fact they just said:

While we make every effort to provide the most consistent, representative performance in our studio-based testing, it is sometimes very difficult. After further analysis we’ve discovered our GFX100 shots are fractionally misfocused, an issue exacerbated by the exacting resolutions of the 100 MP system. While these images show that the GFX 100 can capture significantly more detail than its 50MP predecessors, they do not show the full extent of this difference. We are planning to re-shoot the scene as soon as a production camera arrives and would like to apologize for any misconception these images may have furthered.

I guess this happens, when you hurry too much. Take your time, DPR, we can wait a bit longer for our pixel peeping. The important is we have a fair test.

The good news: even misfocused, the GFX100 is the sharpness king :)
