Almost all mirrorless cameras are WYSIWYG: “What You See Is What You Get”. That’s all the current mirrorless cameras except for two cameras: The Leica M serie and the Fujifilm X-Pro serie, but the X-Pros are both Optical ViewFinders (OVF) and Electronic ViewFinders (EVF).

WYSIWYG is a computer acronym that was first used by MicroPro for their word processor: WordStar. That was in 1981, long before the Mac or the Windows computers. They didn’t create the WYSIWYG technology. That was created by Xerox in 1974, but MicroPro created the acronym because they could display styled text like bold and italic.

The beauty of mirrorless is that you can see what the image will look like before taking the picture and you don’t have to chimp at the LCD afterward. The problem is that there are occasions, like when using flash, where you can’t preview the image because the light doesn’t exist yet. So Fujifilm, like all the other mirrorless manufacturers allows you to configure how you can preview the image.

MENU > SCREEN SETTING > PREVIEW EXP./WB

  • PREVIEW EXP./WB: ON to preview the exposure and the white balance preview when in manual exposure mode
  • PREVIEW EXP./WB: ON to preview the white balance when either in aperture mode or shutter speed mode.
  • PREVIEW EXP./WB: should be OFF when using flash or anything that will cause the exposure to change when taking the photo.

MENU > SCREEN SETTING > PREVIEW PIC. EFFECT

  • PREVIEW PIC. EFFECT: ON to preview the film simulations, the white balance, and the other settings like contrast, sharpening…
  • PREVIEW PIC. EFFECT: should be OFF when photographing in low-contrast (like fog), back-lit scenes or hard-to-see situations.

Speed up the EVF

Turning off the previews will allow you to see at a faster refresh rate when panning.

  • The EVF refresh rate of the X-PRO2 is 85 frames per second in high performance power management.
  • The EVF refresh rate of the X-T2 is 100 frames per second with the power booster grip or 60 frames per second without the power booster grip.
  • The EVF blackout time of the X-T2 is 114 millisecond with the power booster grip or 114 millisecond without the power booster grip.
  • The EVF refresh rate of the X-T1 is 54 frames per second with the power booster grip
  • The human eye can see the the motion at around 120 frames per second (early adult with excellent vision)
  • The OVF refresh rate is the refresh rate of the human eyes
