Re: Panasonic 100-400

I read of some owners sending theirs back then being issued with replacements from Panasonic.

I was always put off buying one of these by the bad/mixed reports of what would be a superb lens for birding etc.
Hi Thomas,

In my household we have both the 100-400 Panasonic and the 300 m.Zuiko

The 100-400 is not mine however I have used/borrowed it at several occasions. The lens is half a year old or so hence is probably qualifies as being of "recent stock". Key takeaways:
- Very light (main reason for buying it as its owner prioritizes portability)
- IQ is very good, softens a bit at the long end.
- Lens feels well built, nice finish
- Focusing ring is smooth
- Zoom ring is a tad stiff for my liking. Not an issue, though.
- 100-400 is useful and opens for additional application areas than dedicated birding photography.
- Good price/performance
- 6 months use so far without any issues

PS lens has been used with E-M1 body, meaning that the lens OIS cannot be taken advantage of at same time as the camera IBIS.

Hope this helps
