At some point I need to invest in a higher quality zoom. I've considered buying a used 50-200 rather than the 40-150 simply because of price differences. Would be interested in hearing more about how the two lenses compare. I'm guessing the 40-150 focuses faster on an E-M1? Any impressions with respect to IQ differences or ergonomics would also be welcome. Thanks. Will probably end up biting the bullet for the 40-150 at some point, but have wondered how the 50-200 would compare.

I have the earlier, non SWD 50-200. It's reasonably close to the 40-150 Pro in resolution and contrast and like the Pro can be used wide open. Focus response is well shy of the Pro and burst rate is limited in comparison. Of course it has the extra 50mm reach and pairs well with the EC14 to make it 70-283. Noticeable vignetting at the long end needs correction in post.

For action work, I reach for the Pro ten times out of ten.

Cheers,

Rick

I have the E-M1 and the SWD 40-200. The autofocus is fast and efficient.

While the 50-200mm SWD certainly is a lovely lens, its ability to AF on an OM-D body isn't even close to that of the 40-150mm Pro. The 40-150mm AF is 3-4 times faster.
