I received my PN-11 extension tube the other day but due to work, had no chance to try it out.... until this morning after work.:biggrin: These are the first images with my 300mm w/Pn-11 The focus is incredibly sensitive and the dang wind was gently blowing so it made it a bit dificult....but here they are. 1. 2. 3. 4. 5. 6.
