I have the 50-200mm SWD and often use the 2x converter with it on an E3
My conclusion after 3 months is that the 2x converter is not great. You
double the f-stop when you put in on. You can only use centre focus not
area/multi. For wildlife I think you need to have as fast a lens as possible
and area/multi-focus so that movement can be captured.
I would like to try the 1.4 - allows a bit of extended reach, still allows
area/multi-focus points and drops less light than the 2x. Also the MTF
charts on Olympus sites show the 1.4 to be sharper.
I think the 2x is good for moon shots or anything which is far away but
relatively still.

Subject: [OM] Long Lens for Yellowstone
I will be visiting yellowstone for the first time. I currently have the
50-200. Question is will that lens be long enough for most wildlife or
do I need to look into something a bit longer.
If I need something a bit longer would I be better off with 1.4x, 2x or
third party lens ?
Thanks
Alan
