Unexplained focus miss

Here's the original shotsoft everywhere--I don't see anything in focus

And a re-take a couple of seconds later:

The only meaningful difference between these two is that I did a -1 EV on the second, which pushed the aperture from f/2.8 to f/3.2. But that doesn't seem like enough to me to account for the focus difference.


It's me? I just didn't have a good focus lock on the first one and need to be a bit more patient?

It's the lens? I think not. I shoot this lens wide frequently enough to tend to discount that.

It's something more technical?  Too narrow a DoF at f/2.8 and this distance to capture a 3D sculpture?

I'm leaning towards the first, but if anyone has any other suggestions/explanations for the difference I'd be glad to hear them.

Quite open, however, to operator error as an explanation
