the film/sensor. The OM 21/3.5, is one example I know of where curvature of
field that's already a bit much at normal close focus gets really bad with
extension. Longer FL MF lenses, such as this <<Takumar are fine on modest
extension.
I wonder how the OMZ 21F2 would do with extension as it has floating elements
and is better at close focusing distances? I had thought John Lind had posted
an image with that combo but it was the OMZ 18mm.

Too close for comfort, Mike
