Nice detail! Does the f-stop recorded in the exif get automatically converted when using the converter or is the f-stop reported what is set on the lens. So the 60-250 becomes a f/6.3 as reported on the top lcd/viewfinder or it still says f/4?

Actually the viewfinder will say f/6.7 if you open it up to maximum.

Thank you.  So you had it stopped down, er ummm (steam coming out ears) 1/6 stop at f/7.1 as reported in exif?  That tells me the 1.7 will cost about 1 1/2 stops instead of 1 2/3.
