Since Fujifilm GFX 50R has a Medium format sensor and Olympus E-M10 IV has a smaller Four Thirds sensor, Olympus E-M10 IV's lenses for a similar focal length and aperture will generally be lighter and smaller than the Fujifilm GFX 50R lenses.

Which camera has more lenses?

Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Olympus E-M10 IV has an advantage over Fujifilm GFX 50R. There are 120 lenses for Olympus E-M10 IV's Micro Four Thirds mount, on the other hand there are only 15 lenses for Fujifilm GFX 50R's Fujifilm G lens mount.

Another important factor is the availability of image stabilization.
