Re: Pana 20/1.7 (version II) vs Oly 17/1.8?? Need help deciding.

I have the version I 20/1.7 and the 17/1.8. By all accounts nothing changed optically or AF wise on the version II.

IQ is nearly the same, I tested mine carefully. Small differences in whether edges or center slightly sharper.

Size wise bulk about the same, 20 wider but flatter 17 narrower but taller.

AF is no contest, the 17 is way, way better than the 20. Fast and quiet. The 20 is noisy and slow.

Personally I don't use the 20 anymore, never did much actually, but the 17 gets pretty frequent use.

To me the 20 is a great optical lens and good pancake form factor ruined by an awful AF implementation. Why they didn't fix the AF with version II is beyond me.

Both will take great photos, the 20 will just do it with noise and slower AF. Not a good choice for video. But if you don't mind the noise and a bit slower focusing the 20 is a very nice lens.
