Zuiko 70-300mm and Raynox DCR-250
Some technical information about using Zuiko 70-300mm with Raynox DCR-250. Skip if you want only photos. :)
All tests on manual focus. Smallest focus distance: 110-130 mm from the Raynox. Should suffice. Largest object that could be photographed: 30 mm. Magnifications and maximum object sizes:
1. Focus at infinity
2. Closest focus
DOF at 200-300 is very, very, very small even at f22.
One of the first acceptable photos I took with it (ISO400, cropped):

Meadow and dandelions
Today the weather was great, so I took some photos in my neighborhood.
Meadow. It's converted from ORF (Olympus RAW file) in Raw Therapee.
A church very, very far away. Zuiko 30-700mm lens are quite handy. You could see the waving of the air - it's VERY hot today.
Dandelions almost in sepia...
