TC questions

Qarik

so I ordered the nikon TC-20III just now to get some shot of Tiger at the fry's open. I plan to use this on my 70-200mm vr2. My questions:

1) I lose 2 stops of light so my max aperture will be 5.6...but what happens to bokeh? Is it 5.6bokeh or 2.8 bokeh

2) will my aperture read 5.6 or will it read 2.8 on my camera body?

You will have the exact same bokeh as if you crop to the same field-of-view on the lens alone.

If the teleconverter is communicating with the host camera body, the body will sense the teleconverter and adjust the metering and EXIF accordingly. I am unsure what you will see in the viewfinder but I believe that it will be correct for the "effective" aperture on most bodies.

Funny. My 300f/4 Nikon read f/4 with the Kenko 1.4TC And my 70-200mm Vr2 read f/4 with the same TC wide open.

With the TC-2eIII on the 200mm f2 I get a 400mm f4 reading on the exifs and the body. I do not notice much change in bokeh.
It was f3.2 with the TC-17. But I notice much better picture quality with the TC-2III.

Oh Meant to mention that Bokeh should look like little dollar signs!
