I tried to stack a reversed 50mm f1.8 on a Tamron 90mm f2.5. Big
vigenetting. With the Zuiko 2X, the vigenetting disappeared. But loss of two
stops, limited focussing light, and 4X magnification. John Shaw mwntions
that he uses a 200mm and 105mm for the reversed lens. To me it seems that
the angle of view of a 90mm is too wide.
Just thought I'd post this.
I've been looking for flower/plant stuff to photo, but with old El Nino,
everything here is dirt.
