Hi Peter
I went out tonight at about 18.00hrs with the 500mm + TC 16A.
I would say the light was exceptional, thats what prompted me to head out, plus I have discovered what I believe is a marriage
between two Kestrels or Hobbies that are living on or near my land. They did not show tonight, but one was travelling along a limb
earlier today with a mouse grasped in its talon, I left the camera indoors and went out with the Binoculars, this is a common
occurrence for me. Camera is now on Tripod awaiting the morning.
Back to exposure talk now, to achieve a correct exposure I chose to use the following settings,
shutter speed of 500ths at F8 , ISO 400. I could have made the f stop wider for a faster shutter, but I am not familiar enough with
this lens to be confident of sharpness wide open with a TC.
I have captured two species of Butterfly at closest focal length 800mm f8 in beautiful light. Be interesting to see the detail that
comes through as I never had the remote shutter release set up.
