Don't beat him up. I just received my 1.4g today. This is my first prime in like 25 years. I was about to post and ask why I cannot get a clear image at 1.4 on my camera and then I saw this thread.

I am not a pro, but I cant understand why I can't get a clear image at 1.4 on my D800E? At 1/2000 it certainly isn't camera shake. I'm just taking a picture of my son.

I am hugely disappointed. It could be operator error but I don't see how it could be. I take the same picture at 2.8 on my 24-70 and it is crystal clear.


You can get absolutely tack sharp results at 1.4. And I mean tack sharp - every eye lash razor sharp.

I think the problem most people have is using it hand held with AF-S. This means that even the tiniest change in distance will throw it out of focus because of the miniscule depth of field.

Using AF-C is the answer. Oh, and never use focus-recompose.

Actually, I usually do use AF-C with the back focus button released from the shutter release, but thought it would be better to use AF-S. I'll try it out again when I get home from work switching the mode.

Gotcha on the re-composing. That was brought up yesterday too. Makes sense after looking at a DOF calculator and the DOF was less than an inch I think.
