The da 70mm looks out of focus in the sharpness test,
and in the outside comparison test the two lenses dont have the same focus point
The da 70mm is way sharper wide open as shown in this test

I have a KPS 1,3x magnifier + F6-A spllit image Focusing Screen, it really improves manual focus a lot. With the kps the screen size comes near a digital FF but it is still smaller then an analog.
Did you calibrate your focus screen with the right shim?

naa i know it was more a psychological post for me ..when you hear 4 times more, this lba thing wakes up, "2stops sounds ok", i have also the 3 limiteds, they are great. they do not have the extra speed, but they are small light and sharp.
I have also a 50mm f1.7 but since i got the 40mm i doesn't use it so often

Some one knows how much of a decentering defect is in range of factory defaults.
I have a second copy of the da 21mm, the first had haevy decentering defect, was like a Tilt-shift lens.
The 2. still shows a bit softer right border-corners, not much but...
keep it or retry?

I have made my own shims with different sized plastic sheets. My - focusingscreen provided 0.25 mm shim was backfocusing. And dust is really a problem when changing more times the shims, to find the proper one, its everywhere on the screen, prism and mirror.
