Fujifilm’s astounding GFX100S
Posted on Jan 27, 2021
The fourth member in the brand’s GFX family is the Fujifilm GFX100S, a 102-megapixel medium-format camera that is portable, versatile and impressively featured.
The GFX system was introduced to bring medium-format digital to a wider audience by offering more affordable and more portable cameras to quality conscious photographers. There are currently three models in the GFX system, the GFX100, GFX 50R and GFX 50S, based on the 44x33mm format which is 1.7x larger than 35mm full frame and what Fujifilm calls large format.
The GFX100S has the same core imaging technology of the GFX100, thus it features the same 102-megapixel CMOS Bayer array sensor and quad core X-Processor 4, but in a body that’s 20% smaller and 10% lighter compared with the GFX100, and it’s priced at £5499 body only so much cheaper too.
The weight and size savings have been possible thanks to a new 22% smaller, 16% lighter shutter mechanism that is still extremely durable with a minimum 150,000 actuations and a new 10% lighter, 20% more compact in body image stabiliser mechanism with a claimed benefit of 6EV, which is better than the 5.5EV gain of the GFX100.
Autofocusing is handled by an on-sensor phase detection system with pixels covering almost 100% of the imaging area and works down to light levels of -5.5EV and can acquire focus as quick as 0.18seconds. An updated focus algorithm helps track subjects in Tracking AF and Face/Eye AF modes.
