Squirrel with Olympus 40-150mm f2.8 and MC20 Teleconverter

Squirrel with Olympus 40-150mm f2.8 and MC20 Teleconverter,
I've been using the Olympus 40-150mm f2.8 for half a year now, I bought the lens together with the MC14 Teleconverter, and that combination works great. A few months ago I also bought the MC20, although all the opinions about it on forums and also from other photographers were very negative.
"It's better to crop your image afterwards than to use a teleconverter" was the message.
But I really wanted to test this out
and here is the result.
Judge for yourself what you think.
