hey guys I was wondering what F stop your using for good pics, I know the pics will be softer with the TC already but maybe at a certain level there is a sweet spot or something
I am usually shooting at 300mm with the Tamron 2x tc, the AF does not work at all at 300mm, I have never had it focus properly its just hunting like crazy.
So I guess that is a second question, how do you know if your focus is good or not at that level? the great viewfinder on the XT its very hard to tell. I know there is supposed to be a red dot show up but it never does not matter what I try, at 70mm it works fine thought. I have taken some pics manually and the pics are not that bad but its very hit and miss. I have tried with IS on and off and no difference
the lens itself takes awesome pics though
