Hi,
I am in need of a 400mm f5.6 (or better) lens for my D700 and have identified a number of options to achieve this. I want to use the lens for shooting wildlife, motor sport and low flying military jets.
Does anyone have any experience of any of the following combinations? If so, I would really appreciate your advice, especially regarding AF speed and sharpness:
OK - I have the following options (in order of increasing cost):
1. I already have an 80-200 f2.8 AF IF-ED (non-AFs) lens, to which I could add a Kenko Pro 300 DG 2x teleconverter, which would give me f5.6 at 400mm and would retain AF. Not sure about AF speed though. Cost approx £150.
2. Purchase a Nikon 80-400 VR and sell my 80-200. I have read the reviews which talk about slow AF, but I have also read the AF speed on the D700 is OK. In most circumstances I would use the focus limiter to (hopefully) improve AF speed. Cost Approx £700 (assuming I sell the 80-200 for a reasonable price)
3. Purchase a Nikon 70-200 f2.8 VR + TC-20E teleconverter and sell my 80-200. Cost approx £1300 assuming sale of 80-200.
I know there are other options (Sigma?) and if anyone has experience of them, or other suggestions, I would be very pleased to hear them.
Many thanks.
