MTF Charts for Fujifilm X100

The MTF chart suggests a lens with outstanding performance showing exceptionally high contrast overall, as well as for fine details.

Most likely the lens peaks at f/4, but Fuji does not supply MTF charts for f/2.8 or f/5.6 or f/8.

Stop down to f/5.6 to retain all the goodness of f/4 but with more depth of field. Aperture f/2.8 is likely to yield the lion’s share of the performance to be gained by stopping down from f/2. Aperture f/8 wil show some loss of contrast, both overall and on fine details, but this should not be only a small concern— use f/8 when needed, but don’t use it if not needed, for maximum brilliance by sticking to f/4 - f/5.6.

Mouse-over the graphs to see f/2 change to f/4. S and M are sagittal and meridional (radial) contrast.
