Re: EC-20 teleconvertor & 150mm f/2.0

i have a friend who use 150f2+ec 20 on E5.
the quality is very high.
just a small minus,600mm (on 4/3) are many times not enough for birding.
as example i prefer my bigma although the quality isnt comparable on bad light.
a real 600mm f4 is considered a dream in canon house...
