Several months ago, I first read about adapters that would allow me to mount my Canon lenses to my new Fujifilm GFX 50S. Interested, I reached out to the various companies mentioned inquiring about their availability and acquiring one for potential testing. Of these, only one, Steelsring, got back to me. After some conversation, we agreed that I would test the unit and write an article as to my findings. Several months later, in December of 2017, I received my adapter.

I was intrigued. When first released, the Steelsring EF>GFX adapter was reported as being the only adapter of its kind which would also property report the Lens EXIF information to the camera and turn off the automatic lens correction (for the Fuji 63mm lens) in the process. Having this ability allows you to create your own special “Lens Profiles” for the camera/lens/adapter combination – something I find quite useful and important.

When the unit arrived, it came in a very attractive wood and aluminum case. It was extremely well packaged and after careful examination appeared to be well constructed as well.

Of course, how these adapters operate is that on one side of the adapter is the Native Mount (Fuji) side, and on the opposing side is the Lens Mount (Canon side). Most adapters are “passive” so there are no contact pins. The Steelsring adapter is of a new generation of mounts that allow a camera to actually obtain accurate focus using “non-native” lenses. In this case Canon lenses.

So, the next step was to mount this to my Fuji GFX and begin testing.

I found the fit to be quite tight and secure, both on the Fuji side and on the Canon side. I would say even more so on the Fuji side. Many of the Canon lenses I found “clicked” right in to place. A few required a little adjustment of the lens release button to ensure they were indeed “locked-in”. Once this was properly engaged, the connection was tight, with no looseness or “wobble” at all.

My objectives were quite simple.

1. Determine if a lens adapter, in this case an auto-focus lens adapter, could provide usable AF accuracy and speed using my existing Canon lenses.
2. Determine if the “vignetting” of these lenses would be significant enough to render them useless or usable for my testing.

Alright, so how to begin?

Fujifilm GFX 50s Complete Review at mirrorlessons

Fujifilm GFX

It’s high time for another Fujifilm GFX 50S roundup… and it’s a massive one :)

The Nikon D850 Vs. Fujifilm GFX 50S comparison makes the start (by camerajabber), and even though the Nikon D850 has for sure a fantastic image quality, the Fujifilm GFX 50S is even better. Of course it’s up to each one of you to decide, if the IQ improvement is enough for you to decide to go with the Fujifilm GFX 50S.

And always keep in mind, that the Fujinon GF lenses underperform on the Fujifilm GFX 50S, since Fujifilm officially said they are designed for 100 megapixel resolution. This means they will express their full potential only in the Fujifilm GFX 100S, which will come in 2019 earliest.

So now the roundup, from the D850 to the GFX, from lens reviews to the techart smart adapter… there is a lot to read for Fujifilm GFX 50S fans :)

Fujifilm GFX Vs Canon 5DSR Vs Pentax 645Z

I thought it’s time to take a break from all the rumors surrounding the imminent launch of the Fujifilm X-H1, X-A5, X-A20, XC15-45 and more, and dive into the Fujifilm GFX 50S medium format world.

This time the Fujifilm GFX 50S with GF 63mmF2.8 has to battle against the Canon 5DSR with Sigma 50mmF1.4 Art vs Pentax 645z with Pentax 55mmF2.8, all 50MP cameras.

But who will be the winner?

The video above has been shared at Sonder Creative Youtube (who is also a member of our GFX group). Some highlights:

• Sharpness Fujinon lenses win hands down. Sharp from edge to edge even wide open.
• He prefers Canon colors, but it’s a personal preference. More accurate and warmer colors.
• Canon focusses faster in low light
• He wants even wider aperutre lenses than the GF 110mmF2. FF has shallower DOF because of the fast lenses available.
• DR on Canon sucks, so he used the A7rIII in this test
• DR on Pentax is best, better than GFX, even if same sensor. Sony A7rII much worst
• Pentax is ugly but user friendly
• GFX EVF little lag to switch on

Fujifilm GFX 50S Vs. Sony A7RIII

So it happened, Sony just dropped another Full Frame camera, the brand new Sony A7RIII (price and specs at BHphoto, Adorama, AmazonUS, FocusCamera).

As to expect, now all possible comparisons will appear on the web, and we have already a first one at imaging-resource, comparing the Sony A7rIII with the Fujifilm GFX 50S, the Nikon D850 and the Canon 5DMKIV.

The results of the 42MP on the Sony A7RIII are, as to expect, impressive and promising. The Fujifilm GFX 50s, Nikon D850 and Sony A7rIII seem to be clearly superior to the Canon 5D MK IV.

“The A7R III has a crispness to the blues in the eye that the other two seem to lack, resulting in a sort of grey overtone from both the Nikon and the Fuji. What may be the most impressive is how well the new Sony FE 24-105 f/4 hangs with Nikon’s new 24-70mm and Fuji’s 63mm. [Note: the Canon had the EF24-70mm f/2.8L II USM]

Due to the RAW profile for the Sony A7R III not yet being available, we are comparing JPEG images. The Nikon D850 image was converted from RAW with ACR default settings“

And here is the EXIF data for the images (shot on a tripod, all shot at 50mm):

• Fujifilm GFX 50S: 1/20th, F5, ISO250, SOOC Jpeg – see here
• Sony A7RIII: 1/40th, F5, ISO250, SOOC Jpeg – see here
• Canon 5DMKIV: 1/40th, F5, ISO250, SOOC Jpeg – see here
• Nikon D850: 1/40th, F5, ISO250, converted from RAW with ACR default settings – see here

As FR-readers noted, the strange pattern in the eyes is very likely caused by the model’s color contact lenses.

Please notice that

• the Fujifilm GFX was shot at 1/20th of a second, whereas the other three cameras at 1/40th.
• the Fujifilm GFX was shot at F5 in Medium Format, which is faster than F5 in FF, so it had shallower DOF
• the Fujifilm GFX could be slightly out of focus, just as the Canon 5D MK IV
• the Nikon D850 is a RAW file convertet in Adobe, all others are JPEG
• eye AF on the Sony A7RIII works great for sure

I’m looking forward to more comparisons, maybe in a more controlled enviroment with all cameras at the same settings (a classical lab test), once Adobe supports Sony A7RIII RAW files.

With that said, go to imaging-resource here and check out their comparison.

Written for Fuji Rumors by Rick Birt of romeobravophoto.com

*Note* This is a long post – I have a summary of pros and cons in my conclusion

As soon as the Hasselblad X1D-50c and Fuji GFX 50s were announced, I wanted one. The promise of Medium Format in a cheaper, and smaller package was incredibly alluring. For the past year my main camera has been a Fuji X-Pro2. I love it. I love the image quality, the colors, the size, and the Rangefinder styling. I also love Fujifilm’s Kaizen philosophy of constantly updating their camera lineup via firmware. All of these things influenced my decision toward the GFX. Luckily, my wife (Kelly Williams), and I were also given the opportunity to demo the Hasselblad X1D. The svelte styling, leaf shutter (ability to sync strobes at 1/2000s), and simple menus were all big pluses in the Hassy’s favor.

When we opened the boxes, we were woefully unimpressed by the Fuji GFX. Even though it kind of looks like a bigger X-T2, it’s actually kind of ugly in person. It almost looks like three different teams designed parts of the camera, and then they Frankenstein’d it all together in the end.

In stark contrast when we opened the X1D box, my wife said,

“We may have to buy two of these so we don’t fight over it.”

Similarly, we conducted two fashion shoots with these cameras. When we brought out the X1D, both models said

“Oh! A Hasselblad!”

Neither commented on the GFX.

Should this matter? My left brain says no. However, it does matter. What is this industry about? IMAGE. These tools are used to take images, because the world has placed value on images of pretty things. Don’t kid yourself, image is paramount in this business – especially in fashion and portraits.

Back to testing…
