Fujifilm GFX100 RF Camera Overview

Introduction

  • Type: Rangefinder-style fixed lens medium format camera
  • Unique Feature: Only fixed lens medium format digital camera
  • Megapixels: 102
  • Design Influence: Borrows elements from Fujifilm X1006

Key Features

  • Lens: Fixed
  • Shutter: Leaf shutter mechanism
  • Built-in ND Filter
  • Combined Shutter Speed and ISO Dial
  • Aspect Ratio Options: Nine different film-based aspect ratios

Film Formats and Aspect Ratios

  • Common Film Formats:
    • 35mm (full-frame)
    • 120 film (medium format)
    • Sheet film (4x5, 8x10)
  • Standardized Film Dimensions: Set height with variable width
  • 35mm Example: Nikon FM2 Titanium (36x24mm, 3x2 aspect ratio)
  • Unique 35mm Cameras:
    • Pentax 17 (half frame, 1.4:2 aspect ratio)
    • Fujifilm TX1 / Hasselblad Xpan (5.4:2 aspect ratio)
  • Medium Format Variations: 645, 6x6, 6x7, 6x8, 6x9, 6x12, 6x24

Digital Sensor Considerations

  • Improvement Over Film: More resolution means more effective resolution
  • Cropping in Digital: Cropping reduces resolution
  • Fujifilm XPro 3 Example: 27 megapixels, cropping to 65x24 gives 13 megapixels
  • Pixel Pitch: Larger sensor can maintain resolution or increase pixel pitch
    • Better signal-to-noise ratio with higher light per pixel

Fujifilm GFX100 RF Specifics

  • Resolution: 102 megapixels with 3.76 micrometer pixel pitch
  • Aspect Ratios Offered: 3x2, 645, 6x6, 6x7, 6x8, 6x9, 65x24, 6x12, 4x5
  • Virtual Focal Lengths: 35mm, 45mm, 63mm, 80mm

Practical Use

  • Testing: Used for landscape and various shooting scenarios in Utah
  • Aspect Ratio Dial: Allows for creative composition in-camera
  • RAW Format: Images can be pre-cropped but adjustable in post-processing

Benefits and Limitations

  • Benefits:
    • High resolution allows for effective cropping
    • Aspect ratio and focal length versatility
  • Limitations:
    • Minimum aperture of f/4
    • No optical image stabilization
    • Not ideal for portraits due to limited bokeh
    • Need for tripod in low light

Conclusion

  • Overall Impression: Fun camera with a great aspect ratio dial
  • Comparisons: Likely compared to Leica Q3 due to lens and stabilization differences
  • Future Wishes: Aspect ratio dial on other GFX models

Final Thoughts

  • User Experience: Versatile but with noted limitations
  • Market Position: Compared to full-frame alternatives like the Leica Q3

Note: The lecture concludes with a brief showcase of comparative photos between the GFX100 RF and film cameras.
