The Medium Format Fujifilm GFX 50S has a 51.4MP Sensor

At Photokina 2016, Fujifilm announced their new system called the Fujifilm GFX: their medium format camera system that has been long rumored. The new system sports a sensor size of 43.8 x 32.9mm; and the camera is being touted as something that is meant to be above full frame camera systems. This is being called the G format sensor and is 1.7x larger than 35mm. It has 51.4MP. At its full size, it as a 4:3 ratio. However, there are a number of different ratios available.

Oh right, and it’s mirrorless!

The new sensor has specially shaped micro lenses and has an optimized silicon process. It was indeed fully customized just for them. No word yet on who makes it.


The camera has a new mount called the G mount, and comes from the company’s long history of medium format cameras. Without a mirror, the lens mount has a flange distance of 26.7mm. That’s quite short! There is a focal plane shutter that shoots up to 1/4,000th; which means no leaf shutter and therefore high speed sync will be less than what you’d expect from more typical medium format cameras.

It has a tilting LCD, an LCD screen on top, has an SLR style body and doesn’t have the electronic viewfinder standard. But it comes with the camera and fits right on top. You also have the option of rotating viewfinders or attaching an external screen via the HDMI output. This includes tether shooting too–something that Fujifilm users will really appreciate! There is an ISO dial just like with the X-T2, which some will appreciate over the X Pro 2’s.


There are also new lenses which are designed to resolve over 100MP. They’re also designed to be distortion free. Among the lineup is the:

  • GF63mm f2.8 R WR (coming in early 2017)
  • GF 32-64mm f4 R LM WR
  • GF 120mm f4 Macro
  • GF23mm f4 R LM WR
  • GF45mm f2.8 R WR

And the cost of the camera with the 63mm lens? $10,000. (This is not official yet and could change.)
