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

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 :)

New Creative Opportunities: Godox H1200 and Crossbrand Adaptations

There are hundreds of modifiers out there with Bowens mounts…but which are any good?

gues post by Markus Klinko

With the emergence of the Fujifilm GFX medium format camera in January of 2017, I became very interested in high speed flash sync.

Until that time, for most of my work, I used medium format cameras with leaf shutters, that provided sufficiently fast flash sync, up to 1/1600, with certain configurations.
But flash duration really was always my main concern, and I simply did not worry about needing to sync at any faster shutter speeds.

As I started to explore how High Speed Sync (HSS) and/or Hyper or Hi Sync (HS) could open up new creative possibilities, in conjunction with a medium format mirrorless camera, I looked at all available options, offered by the established companies such as Broncolor, Profoto and Elinchrom.

It is important to be very clear that there are basically only 2 different ways to sync at high shutter speeds: With HS, as used by Broncolor and Elinchrom, a very long flash duration is needed to provide a flash long enough, where a portion of that flash can be efficiently synced up with the shutter at high speeds. With HSS on the other hand, (the brands that use this method, such as Profoto, Godox, Jinbei and many speedlites), a rapid sequence of pulsating flashes, creates a very even and reliable solution. While HSS provides a smoother and more even exposure, it can lack the power of a ‘normal’ flash.

For almost all of my career, I exclusively used Broncolor, and even collaborated with the brand for about 10 years, for many marketing and promotional campaigns, including their launch campaign for the original Para 330, in 1999.
