Hopefully this image shows the delicacy and nuance that this lens is capable of, it's an image of a glass artifact that looks to me as if it was a lens made completely out of glass including the barrel.   I've called it 'Glass Noir'.

The VPM in 286mm mode is very soft, but still capable of detail @ wideopen as this image is.   This was w/bellows extension out to 21 inches on my 810 including my reducing back and 4x5 ext. sleeve as I couldn't get enought extension to get close enough w/my 4x5 Toyo, and this SM was close.

I love getting close w/these lenses which helps to blow up and sometimes blow out the background versus foreground clarity.

Take care
