K-3 with Samyang 16mm f/2.0
This lens does architecture quite well. There is some minor distortion but I personally don't find it distracting. It is significantly better than the DA* 16-50. I like both of these shots equally. The whole conservatory is shaped like a squared off C with the main vertical bisecting the large dome. There are smaller atriums at the corners of the main vertical and the two horizontals and small domes on the corners between the two horizontals and the smaller right side verticals. First shot is obviously the main dome/front entrance. The title is "1899" The roman numerals above the entrance read "MDCCCXCIX" hence the 1899.
Second shot is essentially of the upper right of the squared off C shape. Liked the reflection in the water garden pool. There are two water garden pools one nestled in the top of the C the other in the bottom. The one at the top, pictured here is tropical, water is pretty much still too cold for there to be much in the way of plants. The water garden at the bottom of the C is for hardy species, and is filling in nicely with plants.
