Thanks Paul,Philippe,mMontag,AhamB,Andreas, and Charles!
I'll take a look at removing the CA in the 1st and 3rd one, thanks for pointing it out.
Alex, like the 2nd shot the best too.
Getting the right thickness adapter really made a huge sharpness difference for shots over 15 ft. away.
Would you mind sharing which adapter you're using now which has the right adapter thickness?
I tried a Contax 35-70/3.4 with an adapter that's much too thin (~1.35mm) and if the lens actually was in good shape (not 100% certain), it caused an insane amount of field curvature and corner blurring. The 35-70 has floating elements so adapter thickness is critical. I returned the lens now so unfortunately I won't be able to test that copy with a better adapter, but I am looking for a better adapter and will buy another copy of the 35-70.
BTW, I had another look at your shots and actually all of them display some CA in some places. It's up to you, but removing it is easy and the resulting image will look more natural and sharper. If you don't correct it you're basically looking at a double image, because green and red colors have a slightly different magnification (that's what lateral CA is). The absence of this is also what makes the images from apochromatic lenses so crisp and clean looking (not like an ordinary photograph which alway has some colour abberations 'overlayed', which reduces the transpacency and naturalness).
