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...) Frank Filippone Red735i at verizon.net 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.
