I love zooming in on beautiful landscapes, waterfalls, birds etc.
This is the sole reason why I purchased this lens, it offered a a 600mm
equivalent in a relatively portable size and considering what it does is great value but now I need more!!!
I'm intending to eventually couple this lens with the EC-20 teleconverter, I'd really love to read any users opinions in relation to how the EC-20 being a
2x converter will impact on the stabilization, image quality and overall speed(according to Olympus the lens used will be reduced by 2 f-stops), thanks.

Hey lone_samurai,

I have the same lens, so i would like the answer to this one as much as you :) I'm guessing the 2.0 teleconverter would make things 2 times as big in width as well as hight, so that should mean it gathers 1/4 of the light the lens would gather otherwise... I'm not 100% sure if that's how it works though...

Thanks for the reply Paukl. I expected the EC-20 converter would to some extent effect the aperture and speed and I guess you could be right about the other point you made because telephoto zoom lenses give the illusion of objects being closer than what they are effecting depth of field and the converter could probably exaggerate this effect.
Like yourself though I'm not entirely certain and it would be good to get an insight from someone who has used them together and share with us some of that first hand experience.
I'll probably end up buying this thing anyway but not for a couple of months,
any more thoughts would be appreciated.

Hi folks,

If you take an ED 70-300mm 1:4.0-5.6 and add a ZUIKO DIGITAL 2.0x Teleconverter EC-20 to it you effectively get an "ED 140-600mm 1:8.0-11.2".

You will not be able to auto-focus with this combination according to this Olympus America web-page.

Bob.

It says: "MF available". It does not say that AF is not available..
Anyway F 11.2 will make it hard to use.
