Gonna make this quick... I finally had a chance to take the Fujifilm GF 80mm ƒ/1.7R WR lens for GFX out on a photowalk to peer thru it from an urban landscape and street photography perspective. Let's say I'm a little more than impressed. There's something about this lens that gives everything a 3 dimensional quality. The subject just pops right off the page. Sure, that's what large bore portrait lenses do but there's something special about this lens, a quality my GF 110mm ƒ/2 lacks. Even compared to the Sigma Art 85mm ƒ/1.4 I previously owned and adapted onto the GFX 50S, the GF 80mm exceeds it in lifting the subject out of the frame.
There’s No Replacement for OEM.. But Wait, There’s More!!!
My real issue is the lack of an ultrawide zoom. 3 years on and Fujifilm continues to neglect all of the landscape photographers they try to market this system toward. There have been rumors of a 20-36mm ƒ/3.5-4.5 but nothing official has been announced. You’d think this would be a priority... instead we got a 50mm pancake, 30mm ƒ/3.5 and the 45-100mm ƒ/4. The latter filled a huge hole in their lineup but the other 2 seem to serve only the GFX 50R buyers. Landscape users are left in the lurch for yet another year, unrewarded for our patience and dedication.
Adapting GFX: Quicker Access to Database Posts
Added a quick link to the header menu as well as sidebar widgets to access the categories menu. That should make accessing posts related to the lens database easier.

Adapting GFX: Sigma 35mm ƒ/1.4 DG Art
Where the Sigma 85/1.4 is a home run, the 35/1.4 is a bit of a mixed bag. For most people, it should be fine. For some, like me, it's borderline acceptable. For those few, it will be unacceptable. In 35mm crop mode, it works just fine, but for any other mode, it will require a bit of cropping and correction. At wide open, there is a bit more smearing in the extreme corners that sharpen up by ƒ/4 to 5.6.
Adapting GFX: Sigma 85mm ƒ/1.4 DG Art
The Sigma 85mm seems to cover all of the imaging sensor with no hard vignetting. Fitment of a Wine Country Cameras 100mm filter holder does cause some very light vignetting at the extremes but is easily correctable. Image quality at the extreme corners and edges is a bit compromised at wide open but shapes up when stopped down to ƒ/4.
Depression and Boredom
I suffer from PTSD related depression that often fears its head during points of boredom. As such, I try to keep myself as busy as possible. It doesn't have to be physical activity, but anything that keeps my mind busy. That means winter can be when I'm at my darkest due to the weather, as my mobility is shunted due to physical disability and limited opportunity to do the things I love most. It's rained just about every weekend since December, and the 1 or 2 dry weekends were tarnished with a week's worth of rain or snow. Unless there's a specific need, I'd prefer to not camp in the rain or snow.
After seeing Jay's macro product shots, I decided to do some floral macros, since I have an arrangement of gerber daisies that's survived since Valentine's Day.
I didn't break out any lighting, shooting at ISO 4000-6400 and 1/100s shutter speed with a Sigma 50mm ƒ/1.4 DG Art on the GFX 50S. Figured I'd try and adapt my muscle memory for a focusing ring that rotates opposite of all other brands.
Anyways, I really need to get outdoors. Hopefully the weather this weekend works out.
Adapting GFX: Test Shots vs Real World and Lessons Learned
Despite white wall tests of the Canon EF 28mm and 135mm lenses showing acceptable levels of vignetting, my first real world use of them ended in failure.
Adapting GFX: Sigma Doesn’t Seem to Be the Answer
After spending a few weeks with the Sigma 50mm ƒ/1.4 Art, I've come to realize maybe Sigma lenses aren't the solution for me. At least the 50mm has a very short focus throw, making manual focus a tedious process, even with focus aids like focus peaking and focus zoom. Autofocus is just too unreliable and slow to depend on for all occasions, making manual focus capability a priority.
Adapting GFX: Sigma 50mm Art Addendum
One thing I quickly discovered is the intrusion of the lens hood when adapting 35mm lenses onto the medium format GFX. Since the 50mm Sigma casts an image circle closer to 40mm, it's going to pick up more of what's on the periphery of the field of view; in this case it's the lens hood.... Continue Reading →
Adapting GFX: Contributing Data
If you'd like to contribute your findings, please include lens specifics (brand, focal length, maximum aperture, lens version, firmware version, and if it's weather sealed or stabilized), adapter used, and camera used. Full sensor sample shots without the lens hood (JPEG, 2000x1500 pixel minimum) needs to be of a white or gray background at the widest aperture at both minimum and infinity focus, repeating this at ƒ/8 and at minimum aperture, be it ƒ/22 or ƒ/32.
Adapting GFX: Sigma 50mm ƒ/1.4 Art
This is the first in a series of posts on individual lenses adapted to the Fujifilm GFX 50S with the TechArt Pro EF-GFX adapter.
Fujifilm GFX 50S, firmware v3.30 (latest) TechArt Pro EF-GFX, firmware v1.01 (latest) Sigma 50mm ƒ/1.4 Art, firmware v2.02 (latest)
Summary: Full compatibility: Autofocus, EXIF OK. This lens shows a correctable vignette throughout the aperture range but is heavily affected by focus breathing. As the aperture shrinks, focus toward infinity causes the vignette to become harder and more pronounced. Despite this, it is easily cropped and corrected while maintaining 45mp or more.
Adapting GFX: The Introduction of 35mm “Full Frame” Lenses on the GFX
As I have alluded to in a burst of recent posts, I am planning to generate a small database of lenses for use on the Fujifilm GFX series. Here's my chance for an introduction to give my rationale and to lay the foundation of this endeavor. I'd like to break this down into three "Y's."
Let's begin with a personal "why": I'm choosing to use Sigma lenses to obtain focal lengths and apertures not currently offered in the GF lens lineup. Fujifilm's lineup is sparse at best, and apertures wider than ƒ/2 aren't represented. It's not that I'm a bokeh whore; it's that I need more light gathering for astrophotography and Fujifilm's widest lens, a 23mm, has a maximum aperture of ƒ/4 and that's just not going to work without a star tracker due to the sensor's 51MP resolution. I'm hoping to print a few of these so what counts for "sharp" on the web doesn't work at 20" print sizes. Other benefits: 35mm lenses are much cheaper, especially used prices, and these lenses mostly have direct focusing units unlike the "fly by wire" systems used on Fujifilm lenses. The GFX system just isn't mature enough to have grown both a complete lens lineup or a diverse used lens market.
