On a trip to Jeongdongjin a couple of months ago my Nikkor 50mm 1.8D lens stopped working properly. Which left me with 28mm and 85mm lenses. This was about the only decent photo I made during the trip, though I did make some video I liked on my phone. No tripod though, so there was quite a bit of bobbing up and down.
