The something wrong was that the lens was no longer at 30mm and no
longer focused at 20 feet. It was then that it dawned on me. This
fully automated, electronic lens returns itself to 12mm and (probably)
infinity focus when it powers down or up (I don't know which). I was
furious. Rain was threatening and I was hurrying to try and get done.
Now I had to reset the lens to 30mm, get out my tape measure again and
place my hat 20 feet away for a focus target before I could get started
again on the top row. Arrrghh! Double arrgghh!
Ah, the glorious advantages of MF lenses. I can understand how AF lenses are
advantageous in situations such as sports photography where quick response is needed, but
for "static" photography such as what you are doing here they are costly
overkill. My Quantaray 24-40/3.5 would have been suitable for that situation.
