Sensor size survey (GFX 50R vs. X-Pro2 vs. M10)


For the longest time, I've been wanting to conduct a quantitative survey of whether sensor size really matters. Every photographer I know cares deeply about sensor size, with the general theme being "bigger is better".

Since I have three different sensor sizes at my disposal, along with three high quality lenses that cover the 63 degree angle of view (35MM equivalent), I thought I'd make an attempt at pulling together a survey.

The three cameras used for this survey:

  • Fujifilm GFX 50R with the GF 45MM F2.8 lens
  • Leica M10 with the 35MM Summilux FLE lens
  • Fujifilm X-Pro2 with the XF23MM F2 lens

Take me to the 3 mins survey

If you don't want to read about the methodology used to normalize the images, please feel free to proceed to the 3 mins survey which can be found here:


There are currently 35 responses. When sufficient results come into the survey, I'll post the results here and also on the blog. Since this is my first survey of this type, I encourage feedback and guidance so that I can make these even better in the future.
