M.Zuiko 45 vs Petri 55 vs M-Nikkor 55 vs ML Yashinon 50

[caspert79]

Bought an E-PL5 last week, so I figured it's time for a new lens test!
The line-up:
1) M.Zuiko digital 45mm f/1.8 (m4/3)
2) Petri Auto CC 55mm f/1.8 (breech lock version)
3) Micro Nikkor 55mm f/2.8
4) Yashinon ML 50mm f/1.7

First the Zuiko vs the Petri:


The Micro Nikkor vs the ML Yashinon:


Then the 100% crops @ f/1.8/f1.7:


100% crops @ f/2.8:


100% crops @ f/5.6:


Conclusion: all lenses show very good performance. Winner is the M.Zuiko 45mm f/1.8. Still have to find a lens in this focal range that beats this one!
