Granted, it's been a week or two, but I just got out to photograph them today.  There were a ton of swans out, to the point it really surprised me.  I'd venture at least a dozen couples, minimum.  Used a lens that is pretty uncommon these days.  What it is is fairly obvious if you look closely at the photos, but I want to see what you guys come up with.  Gotta say, it is interesting to try to run a manual focus lens, take photos, and control a tripod at the same time. 

Pretty sure the first one was a pre-owned model as it kept walking like it's neck hurt.
