It's nice to have the bulk of metal and glass available. Paired up with a PK-3 macro extension I can play with a frightfully narrow depth of field, which will do wonders to reveal my clumsiness as a photographer.
Of course, preceding this, I had done a number on the condition of the sensor. Lint free cloth is your friend. I wound up following the procedure outlined at http://www.cleaningdigitalcameras.com/ and attained satisfactory results.
The brass knocker is a full frame shot, illustrating the edges being free of phantom tentacles.
I also received my 1/2" 10tpi ACME tap yesterday, so hopefully I'll have more machine content soon enough.
