well my friend i did not want to participate in this thread until i give it enough time of trial.
now i got it for about 2 months, i can tell you honestly compared with Zuiko 70-300 mm, it is fantastic, if you can afford it go for it and don't hesitate. it is in England about 1000 pounds but i got it from the states for about 1000$, which makes it about 2/3 of the price (i guess).
i will start with the cons:
1- it is heavy, but not 100% impossible to be used hand held, this goes for me, for you gays you will cope with it much easier than i do, but still a tripod is a must.
i got photo 1 and 2 shots i use it hand held, but you have to keep in mind that over here it is very bright and sunny most of the time so with ASA 400 or 620 you are fine specially if you are shooting against a bright BG.

2- slow focus, yes to some extent but on the other hand you can control the focus manually and the MF ring is placed just in the right place that makes reaching to it very easy and convenient and it works without the need to turn its button on.
3- It works with the 1.4 TC well but don't go all the way to 500 mm stop at 470mm, go for as low ASA as possible and once again light BG.the attached shot is with the 1.4 TC i know it is not the best in sharpness but you have to consider that this pirina is hyper active and this was 45 mints after sun rise the light was not strong enough for smaller exposure time.
other than these three point all are pors, very fine optics great accurate focus, use the multi points one for distance moving images like flying terns, and the single focusing point for small close subjects, does not need the IS of the camera, i have not used it with this lens, but have to use it all the time with the Zuiko 70-300mm, btw never also used it with the other Zuiko lense like the 45-150 mm and the macro 50 mm.
i hope this make sense to you, i am not a professional , so what i am saying is what i know by experience only..
