[Leica] I can manually focus more precisely than my A7.......

[Frank Filippone]

I have learned this lesson several times.  I forget it as many times.  Maybe
this time I will remember that this lens is just not too great.

I think the Kit 28-70 is one of the .... just not bad ones....

Next time I get the urge to AF, I will take my D7100.....wider range lens
(equivalent to 24-130), and AF works well.  ( 24MP is 24MP, so by that
criteria, they are identical...)

I find that MF beats AF on my Sony's if the lens is stopped down.  Wide open
the AF usually beats me, but even here, I use it only with the AF button,
not on AF mode all the time.

I also notice a big difference between the really good lenses and the just
not bad ones.

So, you may well be seeing a combination of effects.
