What lenses are usable with the ec20?

[Steve Adams]

I am looking at getting an ec 20 and I am wondering what lenses work with it?

All 4/3 lenses work with it! But for best performance, you need f/2.8 lenses, as this will give you an f/5.6 aperture.

It is best with the 50mm f/2, 150mm f/2, 300mm f/2.8 and the f/2 zooms, but people do use it with the 50-200mm f/2.8-3.5 as well.

Ahhh. so no go on the 70-300mm for example

It will work with it, but the sharpness just isn't there, and you are heavily limited by aperture. A lot, however, depends on your viewing size. If you're looking at pictures on your phone, it may be fine.

Here's a couple of full res samples of the 70-300mm with the EC-20. Do note that these are the best couple of shots from a couple of outings with it, most pictures were just meh.

Ok. maybe finding a 135-400mm sigma would be the better bet then.
