The YASHINON DS-M 50mm 1:1.7 is a good lens for manual focus work with a good color rendidtion and a very good bokeh. Its not as sharp wide open as the TAKUMAR 50 2.0 or the LEICA 50mm 2.0 at F1.7 vs the F2.0 lenses but the the build quality is on the same level due to its all metal housing, the exact aperture ring and a smooth consistent focus feeling. All in all its a again a joy to use this littl lens adapted on a FUJI X camera.
The next series show example captures at F2.8. on the left and F1.7 on the right side.
