Using A Teleconverter On Nikkor 300 f/4.5 ED-IF AIS Lens

Looking at some JPEG files in Preview (the OS X program) it looks like Nikon cameras report "focus distance" but Canon cameras don't.

 

Also, as is well known, Nikon reports shutter count but Canon doesn't.

Cents? Two perhaps?

Irrelevant comparisons perhaps?

Allow me...

See below: European Robin only 1,5 months ago. D800 with 400/3.5 + TC301 and a little extension, on somewhat wobbly Sirui baseplate on rather sturdy Sirui ballhead and very sturdy old Gitzo 500-series clunker (weakest-link and such...)..

Sorry to be pedantic, but how do you get an aperture of f/5.6 with an f/3.5 lens fitted with a 2x teleconverter?

Do you mean f/11?

 

Do the TCs change the data passed through to the computer in the camera, so it knows the real aperture?

:)Don't worry! yes: the lens was set @f/5.6, but the effective aperture was indeed two stops darker..

 

And to me it was just a reminder that I should do this more often! even though it's always a hassle, bringing the heavy tripod and big old lens.
