First up, a squirrel. I forgot I had the camera still set to centre-weighted instead of spot, so the metering was way off. (It's cropped slightly on the right; dead-centre of the frame is roughly where the squirrel's eye would be.) Tried fiddling with it in post, but it was too noisy after lightening. However, converting to B&W and upping the contrast gave a nice sharp silhouette.
Secondly, another set of flowers. Probably between f4 and f5.6, as the bokeh appears to my eyes to be a little more defined than f3.5. An experiment in PP; it's not quite what I had in my head, but it's close enough to leave me not dissatisfied with it.
