A very long time ago... I tested the AF speed of the 40-150 MK1 and compared it with the 50-200SWD, both on the E-3. The test was conducted indoors during an evening, so the light was not very good. The 40-150 was as fast as the 50-200SWD on the same target and I never really regarded the 50-200SWD as a fast focusing lens, it is far too slow for the price. The only thing I did not like about the 40-150 MK1 was that the front lens was rotating, otherwise it was an excellent lens.

Edit: I just realize that this is the MFT forum. I have no idea about how these lenses perform on any MFT body, but the 50-200 is a heavy lens and it needs a lot of battery power. I found the focus motor quite weak, this was noticeable when I aimed the lens upwards. I don't think there was anything wrong with my lens, it is a very front heavy lens, especially at 150-200mm, where it extends a lot. On an MFT body I think it would look bizarre and the batteries are too weak for that.
