I currently have a D300 paired with a 70-300, but want the extra reach.
I have a bunch of options in my head at the moment, but I don't know which is better:
1) Upgrade to a D7100 and crop my photos
2) Get the new 80-400VRII
3) The 70-200 f2.8 with a 2x Teleconverter
4) The 70-200 f4 with 2x TC + D7100 for compability shooting at f8.
I'm just wondering how the AF is affected (slowed) when paired with a 2x TC. Any experiences?
I didn't like the first gen 80-400 because I found the AF was too slow, and just wondering if a 70-200 with 2x would be even slower. Like to hear what you guys think is the best bang for the buck conscious.
