35mm “Full Frame” Lenses on the GFX: An Introduction

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.

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.

So, Why All the New Filters?

What may just look like wasting money, there’s an actual reason why I’ve bought into the Wine Country Camera filter holder system and round filters to replace the kits I had before: I’m planning to purchase a Fujifilm GFX-50S by year’s end.
