I've used the 55-65 end of the PLM's range to take panos from lookouts on coastal trails a number of times. No quick examples available to, but it works very satisfactorily to the point I almost have quit using wide angle lenses on longer hikes as in that specific use 10-20mm (my wide angle lens) wastes too much on the sky and foreground for the effect I'm looking for anyway.
I usually stitch with Hugin.
Wait, I did find this one. I remember it's a well overlapped 2 row by 5 wide pano at 55mm. Sadly I cannot remember if it was the 16-85 or the 55-300 I had mounted but it was one or the other at that f.l.
At full res and printed, the resultant 26 Mb jpg is a very satisfying, quite detailed pano (those little white dots out by the head are boats that can be clearly seen at full res) of the arm where my marina is located.There are some tiny stitching errors on the ocean horizon, but they are hard to see. For scale, the ~250' head is about 4 km away, the hill on the right is Butterpot Mtn and is almost exactly 1000' at the top, the island on the right horizon about 25 km, and the land on the left horizon contains nearly 1000' hills about 50+ km away at their furthest extent.
