May with the Tamron Adaptall2 SP 500/8 on the K1.
It's been a fun month with this lens, even though the depth of field is very thin and, being a fixed f8, the viewfinder can be quite dark. In consequense, I missed focus on a lot of occasions. The use of a tripod and the back screen on the K1 would have helped, but I can rarely be bothered lugging a tripod around and I dislike using the screen. So it's my own fault. The image quality is pretty good, even at the higher ISOs needed. The 1:3 'Macro' and minimum focus distance of just under 6 feet (1.7m for those who use the new-fangled metric system) make it useable for those garden safety flower shots.
Some of my favourite shots from the month:
