1.4 tele

just got a tamron 1.4 teleconverter and it will AF on my tamron 200-500 so hopefully tomorrow it won't rain and I can see how it does at forsythe now with an effective reach of 1050mm. it is now minimum fstop of f9 instead of 6.3
it will also af on my tamron 70-300 f4 to f 5.6

 

Nice, you should be able to get right up in there now! ; What was the damage? ;

 

it was $225. it is there SP one which is there best.
nikon's is almost 500. they are nuts

 

I wonder if it will AF with my Nikon lens?

 

next time you come down you can try it. I tried it on the nikon 18-105 and it autofocused

 

Sounds like a plan! ; Good to hear it worked on your Nikon lens.

 

did a quick test of it on the back nest using the tamron 200-500 and the 1.4
no cropping done. I can see I am going to like this as it gets me really close

I guess you spoke too soon?

 

yes. it is ok for birds sitting still but trying to get a focus lock on them in flight is almost impossible
