21 limited vs 16-45 f4

[Joseph Tainter]

I can offer a roundabout comparison:

I have tested the FA 20 F2.8 against the DA 16-45 set to 20 mm. The test 
was for sharpness, with the subject a mud-brick wall. The FA 20 
definitely wins.

I have tested the FA 20 agains the DA 21. Same test for sharpness. They 
are very, very close. I call it a draw.

Therefore I would be very confident that the DA 21 is sharper than the 
DA 16-45 at 21 mm.
