GF 80mm ƒ/1.7R WR, Continued

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.

Review: Fujifilm GF 23mm ƒ/4 Ultrawide Lens for GFX

Waiting intensely for an ultrawide zoom lens for GFX, I was forced to get something, anything, for certain landscapes and astrophotography. So, until that lens appears I’ve decided on the only lens available: the GF 23mm ƒ/4.

Review: Fujifilm GF 100-200mm ƒ/5.6 OIS Telephoto Zoom Lens for GFX

Giving up a stop of light in exchange for 100mm of zoom range, the GF 100-200mm manages to be light and compact. For more range, it’s compatible with the $850 GF 1.4x teleconverter, bringing the maximum focal length to 280mm but at a minimum ƒ/8. Not all is bad news though: you get excellent OIS and weather sealing, a 67mm filter thread for more reasonably priced filters, a removable tripod foot, a slim profile that’s smaller than most 70-200 ƒ/2.8 lenses and a price of just $1999 USD.

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: 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: Canon EF 135mm ƒ/2L USM

There are some drawbacks though. Uncannily enough, they’re the same as with the Canon EF 28mm ƒ/1.8 USM: slight vignette with a hard vignette at infinity focus. At ƒ/8, it isn’t very prevalent as you’ll see in the samples, easily corrected with a 5:4 crop that retains 48MP. However, as the aperture gets smaller, the vignette hardens, as you can see at ƒ/32, but still works at a 5:4 crop ratio. The lens works fine with a 3:2 crop at full sensor width and in 35mm crop mode, so you can choose what works best for you.

Weirdly, the lens changes focus as you move in and out of playback mode on the GFX...

Adapting GFX: Canon EF 28mm ƒ/1.8 USM

Widening out to an approximate 22mm in 35mm format terms, the Canon EF 28mm ƒ/1.8 USM does show some hard vignetting that is never fully resolved. It’s very, very slight and occurs at ƒ/4 and smaller at infinity focus. Vignetting is prevalent fully open, mostly disappearing by ƒ/4 at close focus distances.

If the vignetting is a problem for you, the EF 28mm ƒ/2.8 IS might be a better bet but isn’t on Canon’s list of preferred lenses for the 5DSR, so it may or may not resolve well on a 50MP sensor.

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.
