50 mm Fourthirds Shoot-out
I just found this article on the net , A Side-by-side Comparison of 11 Different Lens Options by Jens Birch.
You can find the whole test here :
I have checked all the photos at all apertures, and in contrary to the writer's findings , I can see the followings :
1) King of sharpness is 50-200 Mk1 at most apertures, which is obviously sharper than 50-200 SWD and even than the 50mm macro I would dare to say as I see there (considering the font and background focuses but keeping aside the bookeh matter in the background)
2) Also 40-150 is so nice specially at smaller apertures.
3) OM 50mm f1.8 , just a $10 lens how nicely competes with a $1000 lens at its zone of confort , amazing !
