The Tamron with the 1.4X extender would not focus in "normal" mode, but it would autofocus in liveview.... but the autofocus speed was very slow.Stig said:Don Haines said:As promised, I took an SX-50 and a 60D with a Tamron 150-600 outside to see how they stacked up against each other for bird photography.
thank you very much!
looks like I might be able to talk myself into, and at least mildly justify the Tamron after all
then again, this was the 1200mm SX50, not the 2000mm SX60... so I will have to talk myself into the extender as well
or realize that I really don't need the 600mm... but that wont happen
btw, also thank you for testing another thing... I believe that I read somewhere, that the Tamron is not compatible with extenders... now, I realize that there wont be any AF, but it seems like it is working otherwise (at least with the 1,4x)
