Another shot of Speedwell, this is the small one, barely 1.8 inch across. The entire plant is about the size of a pencil, the whole picture shows an area maybe the size of a postage stamp...
Did some experimenting with a Panagor 2x teleconverter (K mount) along with the binocular lens macro rig, not sure if I'm happy with it. While it seems to do fairly well, it looks a bit soft to me, and this is after a little sharpening. That helped, but it still seems a little on the soft side. It's a Dwarf Dandelion I think, but not positive.
ANother with the same rig, also posted in POTW, this one was not sharpened, this is exactly as it came off the camera except for a slight crop. I think it was cropped at 3072x2308 so it would resize to 1024x768 correctly.
The top picture was taken without the TC, all shots taken with SMC Pentax A 50mm f1.4 and binocular lens.
