Image taken in SE Florida last year -

Africanized bees have invaded Florida, and take over many nesting boxes placed for wood ducks, owls, and other larger birds. This is a problem, since owls, particularly, are already losing natural housing in many areas of the US.

It's apparently not only a US problem. Here is a report from Australia:

The face of the bird house is pretty much in focus, but this is truly a study in DoF.

Just running through the calculations, the razor thin depth of acceptable focus isn't making sense to me with the parameter values you have given for focal length and aperture.

I am wondering whether you might have been able to go a couple of stops higher in ISO and perhaps gained some benefit in reduced aperture there or pushed the envelope shooting in RAW and revovered something at the high end that your could have translated into better DoF?

As it stands, I love the concept, but dramatic decline in range of acceptable sharpness kind of kills it for me. Maybe a crop?

I don't see a DOF problem. I think what needs to be in focus is in focus. Just my opinion.

I think the DOF is fine, focus is right on the target. I find this a little creepy.

Focus is fine IMHO :smile: Your photo certainly illustrates a growing evironmental problems. thanks for sharing, but wish is wasn't so :frown:
