I received a request investigate whether the histogram in the GFX cameras when the display mode is set to “Natural Live View” faithfully represented the raw histogram. Spoiler alert. It does not, at least in all circumstances. I’d never paid any attention to that mode before. I looked it up in the GFX 100S searchable… [Read More]
Leica 90/2 Apo-Summicron ASPH-M on GFX 50S
The M-mount Leica 90 mm f/2 Apo-Summicron is a special lens. Almost as expensive as the Otus 85/1.4, it doesn’t quite measure up to the Zeiss lens in the standard lens quality metrics. But in spite of — probably because of — its optical deficiencies, it does a superb job of rendering some things. In… [Read More]
Leica 280/4 Apo-Telyt R at 950 nm on GFX 50R
I tested my LifePixel-modified (720 nm option) Fujifilm GFX 50R with the Leica 280 mm f/4 Apo-Telyt R lens and a 950 nm lowpass filter. I added a +100 contrast boost in Lightroom. Poor coverage, no hotspots. Still has corner vignetting. No hotspots. A little bit of corner vignetting. No hotspots. No corner vignetting. No… [Read More]
Fujifilm 250/4 in 830 nm infrared on GFX 50R
I put a B+W 830 nm lowpass filter on my LifePixel-modified (720 nm option) GFX 50R and checked for hot spots on distant scenery with a +100 contrast boost. Well, that’s encouraging. How about with the Fujifilm 1.4x telextender? Not good at all. Hotspots at every… [Read More]
Leica 280/4 Apo-Telyt R on GFX 50R in infrared
The Fuji 250 mm f/4 G-mount lens doesn’t hotspot with a 720 nm conversion down to f/22. It does hotspot with the Fuji 1.4x teleconverter at f/11 and beyond. That’s a good choice for IR photography at 250 and 350 mm, but I wanted to try something else. Using a Kipon adapter, I mounted a… [Read More]
