You know its coming up to Christmas when the Agapanthus starts to bloom. Mine is always a bit later than everyone else's because its in shade a lot of the time. Shot this with the K-5 and my now quite elderly MC Rokkor f/1.4 50mm lens. It was left over from my film SLR days. I love the really thin DoF that I can get with this, and some of my other prime lenses. Agapanthus by kyte50, on Flickr Its actual focal length is a bit of a mystery. Its 50mm in the old money, but I have to use an adapter for it to work on the Pentax, and the adapter has some glass in it, which will affect the optics and f/l, not to mention the difference because its a full frame lens on a crop sensor. I tried to get the same shot from my 50-200 zoom, and found that I had to shoot at 125mm (f/4), and even that did not quite make it. I need to find some easy way to check the real focal length of this lens, not that it matters that much, but I am curious.
