Just got back from the trip but without any photos to show (yet). My brother chauffeured us around, which saved me having to remember how to shift with the left hand. After visiting Stonehenge we stopped for dinner before he dropped us at the airport. Since his van had a broken window, he placed the camera under the seat so it would be out of sight while we were in the pub. As you can probably guess, in the rush to unload at the airport, the camera got left under the seat. By the time I realized, he had driven off and I was unable to contact him again until too late. Anyway, he is going to backup the photos and mail the SD card (e-mailing the raw files would be a challenge). I felt pretty stupid but at least I don't have to take a camera body on the next trip (also glad I have a backup here).
We went to Stonehenge on January 2nd and it was surprisingly busy, with a long line to get the bus to the stones. The weather was typical for the time of year, cold and breezy, with a lot of clouds and a light misty drizzle for good measure (no golden sunset this time). At the closest point to the stones, the path was so crowded with selfie takers that it was impossible to get a good shot. I would suspect a wide angle would have been needed here to get everything in the shot. On the other sides, the path was further from the stones and I was able to get everything in using both the FA 35 mm or FA 50 mm depending on the spot. The light was not great, so the ISO had to be higher than I would have liked. I did try putting the K-70 down on the ground and using the pixel shift resolution, so we will see how that worked (I definitely had to wipe the drizzle off the front element after that).
Thanks again for everyone's input. Once I get the files I will try and post some shots.
