Not ordered through Amazon, but another Webshop (sorry, but the time was 45.- cheaper) the lens was delivered in no time.
About the Lens:
+ Builds flat, compact and very light (Oly OMD M5 20 / F1.7 fits in your pocket)
+ Looks well made, nothing rattles (unlike the Sigma 19 / f2.8)
+ Relatively inexpensive 17mm compared to Oly
+ Useful imaging performance from f / 1.7, good from f / 2.8 and sharply af / 5.6
- AF could be faster, but can be well manually focus with AF-S + MF setting
Since 20mm for me now is not necessarily the Action lens I can live well with the AF speed.
The important thing was compact dimensions, light weight and Lichststäke at high imaging performance.
Conclusion:
Ranging from the imaging performance between f / 1.7 and f / 4 does not serve up some Olys, but is a fair objective at reasonable price that will accompany me now first on the OMD.
Highly Recommended!
