Went out to the Japanese Tea Garden again, just this time with a lens i haven't used for flowers before, shot it wide open and got to like the results. Out of came (resized) jpg since my raw processor doesn't support the cam yet and well, what's included is a pin to use
K20D with Super-Takumar 50/1.4, the old (radioactive) single coated lens.
Focusing with the K20D viewfinder is a joy, compared to the 30D viewfinder, it's a difference like day and night.
