I won't be lifting from the knees, my back or from anywhere else. I had a hernia repaired on Wednesday and for at least a month someone else will be doing the shovelling. So I won't be looking at any strange turquoise-blue-green colours in the snow for a while. But what I am going to do is some macro tests whilst recovering:
A real Macro Lens (Sigma 50mm/f2.8) compared to -> a variety of other lens combinations including the Panagor Auto Macro Converter with various lenses, reversed 50mm/f2.0, 50mm/f1.7 on the ends of other lenses, and so on. I have no tubes, so am bound to use just the centre of the field in some images. But the magnification is going to be quite high anyway. Anyone care to suggest combinations? I was thinking of using a 135mm with a reversed 50mm lens. the 135mm with the Panagor, some 50mm lenses with the Panagor and compare pictures taken of the same object under the same conditions. A nice little piece of Vypro mesh left over from my surgical procedure!
