I obtained a lens from e-bay and I wanted to try it out with flash on a subject that was in a "still life" type of shot.
Here's the result:

The lens is a 50mm f1.7 manual focus type - but it is 25+years old. It is built like a tank, the glass is clean and unscratched, no fungus - and best of all it just fits on my camera with no drama at all. The price? £27.
Colour me well pleased!
Note that in the exif information shown in the actual Project 52 gallery the f-stop is given as zero - this is because the lens is old that it doesn't pass any information back to the camera. With this lens on the Pentax K200D it asks you at start up what to set the focal length to - 50mm obviously - and from then on, it "knows" how to handle the lens.
Here's the setup shot:

The single flash can just be seen in the top left corner, and the two reflectors were an attempt to soften the shadows at the bottom of the flower. A radio trigger was used to fire the flash, which was set to manual, 1/4 power, and zoomed right out. Post processing consisted of an "enhance preset" in Aperture and a little leaning on the recovery slider to tone down some highlights.
For the purists ( or the judges at my club ) I know the left rear petals are actually not sharp, and I know it is because I did not have the camera in a parallel plane to the flower, so let me just say it for you:
"This is a nice picture of a daffodil, and it would have scored better, except that it is not sharp all the way through the frame. This scores 11 out of 20".
My reply is: "I like it", shrugs shoulders, walks away.
