Two days ago i got this old and once renowned TC , havent found much info on the net or this forum so i thought of conducting unscientific tests with it ,so here goes the images , all photos were taken on a NEX-3 + built in flash in RAW and then exported via lightroom ,resized at 300 dpi ,no pp done, this first series is with the Vivitar 55/2.8 macro lens
fullframe shot + 100% crop
At f 2.8

So IMHO the tc does affect sharpness and contrast and fstops but stopped down the images are usable ,only one bigdownside is the loss of light ,so for macro shooting i will have to get a good flash!!!! i know this is not a permanent replacement for a 90/100 mm macro lens ,but its good work around!! i will post few more tests with mid tele lenses ,as i dont have anything above 135mm so lets see how it does with tele lenses . please do comments your thoughts.

Better than I would have thought for most TCs
There is a temptation to use TCs with the lens wide open but of course this is generally a mistake.
You are getting good results at f/5.6 or f/8
