FWIW, dpreview isn't all THAT impressed it seems. Quite pricey for what is.

Sigma will rejoice - their 100-400mm DN is surely on the same level at the very least.
The sunstar pics on the Pana website are sort-of nice though.

Price-wise it appears somewhat in line with the Canon 70-300 L. Mind you, that one was a shock when it came out - back then, it looked like Canon was aiming to take out all the consumer full-frame lenses, leaving only L lenses and EF-S for everything below. Thankfully either the impression was false, or they reversed course shortly thereafter.
I wonder how this one compares quality-wise... it sure is large, and a 77mm filter for a lens in this class is a new thing (even the Canon L had a 67mm thread, and the Tamron a 62mm one, even though the Sony G displayed upward creep by using 72mm filters...)
I'm wondering why the dpreview folks are shooting at these insanely high shutter speeds (& ISO settings).
Unlike the comments in their video, it seems to be a pretty sharp lens at 300mm though.

Looks sharp to me, plus the build quality and compensation for focus breathing, plus 1:2 macro at 300mm does not come for free.
I bet they will be licking Fujifilm's boots regarding XF 70-300 - a $799 APS-C lens.
You just can't have too many lenses...
