Ahmed,

 

I have forgotten which of these works, but here's a good source:

The Divinycell looks pretty good.

 

Googling for "syntactic foam" might get you some other sources.

 

I've made floats out of similar stuff; it doesn't compress at all at recreational depths.

Ciro,

 

No autofocus data yet. Probably in about three weeks - after my next dive trip.

 

Leading theory now is operator error...

 

I will report results.

Drew,

 

Thanks. I think I may have identified the problem: the operator.

 

Let me publicly embarrass myself by saying it could have been in MF when I thought I had it switched to AF :nea:

 

Not sure - going diving at the bridge next month so I can test the theory.

 

I need a monitor that has no whiteout when glare hits it, and has a few vital bits of info that blink. I sure miss my Pentamirror.

 

More next month, or Aug for sure,

 

Tom

kc_moses,

 

I understand the hunting focus when contrast is low. That does happen.

 

My real concern is that the camera focuses on the background - perfectly sharp - when a fairly good contrasting subject occupies the center third of the frame. The camera does not focus on the subject, but instead focuses on the background at the edges of the frame.

 

This happens with the flat port and with the macro lens flipped in front of the flat port.

 

Frustrating...
