Re: 50-200 SWD vs. 40-150 PRO AF Speed on E-M1 firmware v3.0?

I use the E-M1 with my 50~200 SWD, and love it! However, AF tracking performance was not good, UNTIL firware 3.0. Now, it is absolutely excellent. I have not had a chance to compare it's performnce with the 40~150/2.8, but like you, I've heard nothing but good about it.

You may wish to read a quck & dirty review I did on v3.0's AF tracking abilities, with several lenses including the 50~200 SWD with it's 1.4x converter.

The review can be founc here: http://www.furnfeather.net/Reviews/ReviewIndex.html

Just click on the second item down.

BTW: I normally use my 50~200 SWD for rodeos, Ice racing (motocross on frozen lakes) and wildllife.

Good luck!
