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.

Why I Bought a Fujifilm GFX

I'm obviously not a professional photographer. Now, some may take that to mean an enthusiast has no need for a "professional level" camera, but that is entirely untrue, even on a general level. What the GFX offers is resolution. 50.1 megapixels of it. What I offer my camera is a crippled body, unable to get the most from any camera body. I can not hike as far, climb as high or go as long as an average photographer. I also cannot drive due to the medications I need to operate from day to day. Because of that, the GFX's resolution returns to me an ability lost by my inability to drive: repeatability.

Another long break but it’s been silent progress

The biggest news was the purchase of a Fujifilm GFX 50S, GF 45mm ƒ/2.8 lens and TechArt autofocus EF-GFX lens adapter. It arrived just before Xmas and I was able to use it for parts of both latter shoots. I also gave it a couple of runs, one from Kerry Park that was foiled by fog, another from Rizal Bridge that wasn't. The increase in resolution is shocking. Shots taken from the bridge could be cropped down to 8mp and were still crystal clear. Also shocking: the size of the uncompressed RAW files at ~140MB each.

Seafair Airshow 2019: US Navy Blue Angels

Shot the Blue Angels performing on Sunday from the top of my condo building. This year, I benefitted from both the autofocus speed of the Fujifilm X-T3 and the reach of the XF 100-400mm ƒ/4.5-5.6 lens. The result was being able to actually see into the cockpits during some of the low passes around downtown. This is also without the 2x teleconverter installed, whose 2 stops of reduced light gathering would have slowed down the shutter speed to being nearly unusable.

Some Deer, Residents of Long Beach

Just a few photos of the local deer on our last morning in Long Beach. They came by for breakfast, the doe bringing her two fawns, approaching our balcony as if she’d remembered that I was out feeding them apples the night before. They sat patiently below our balcony as we dropped bananas and apples for them, posing for photos before moving on to the next set of condos. These deer definitely have us trained well.

The Fujifilm X-H1 Needs a Real Reason to Exist

Like it or not, the Fujifilm X-H1 has no real reason to exist. If the X-H2 is to happen, it needs one to justify its status as the "flagship" of the X-series range Fujifilm claims it to be. When it first came out, it was $2000 for basically just a $1500 X-T2 with a bigger grip and IBIS. Sorry, but that's not gonna cut it if they plan to release an X-H2 with X-T3 guts at the end of that product's lifecycle, especially if they plan to price it above $1500 again. It needs a real reason to exist and I have an idea.

Has Fujifilm Abandoned X Raw Studio?

Maybe you've heard of Fujifilm's mostly ignored software companion, X Raw Studio. It was released sometime after the X-T2 and advertised to leverage the power of their X-Processor Pro image processing engine, aka onboard CPU, to post process your photos on a desktop or laptop computer. It did this by connecting your X-Pro2, X-T2, X-H1, or X-T3 via USB 3 or USB-C's superspeed bus and would allow you to edit your RAW files on a computer but would leverage the high speed bus and X-Processor Pro's power to process the images. Since it's release, it's sat collecting dust with only minor bug fix updates since, while Fujifilm has established partnerships with brands like PhaseOne's CaptureOne and Skylum Luminar to natively support the X-Trans system. All of this seems to be the result of traditionally poor support from Adobe, the long-standing leader in the industry. But I have a vision.
