I have an Nikon D600 and I need a medium telephoto, compact an relatively light that I can use with TC.
I am considering the newer version of Nikon 300mm f/4.0. I will use it in combination with tcs.
I am planing to use the Nikon TC-20E III and the TC-14.
Information I will like to have:
1. Any experiense will help, as images.
2. Autofocusing with the TCs.
3. Sharpness with the TCs.
I did saw this ones : http://www.pbase.com/ronnie_14187/image/57655589
But I will like to have some hands on experience. The Nikon 80-400 and the sigma's 120-400 are heavier and I belive they will have less resolution at long distance than the pure 300mm and I hope that at 400mm the 300mm +tc will be competitive with them.
Please let me know your experiences.
