I was recently unfortunate enough to badly damage my number one birding lens a Tamron 70-300 AF.
With loss of Insurance excess It is probably uneconomic to claim.
Have a 20 year plus Tokina 100-300 F5.6 manual and after testing @ wildlife park today it appears that provided there is front lighting the AF is probably not a requirement.
Here is an image taken with the Tokina wide open @ F5.6 with a Tamron 1.4 TC.
Slightly cropped but otherwise unedited.
Comments appreciated.
My SLR is a Pentax K10D.
