Here is a photo of my bird Mickey I shot while playing around with a Kenko 180 degree fisheye lens. It was mounted onto the front of my 135mm Nikkor which was mounted onto my Bronica S2A.
I used a #6 flash bulb to light it with. Using a focal plane type bulb allowed me to shoot at 1/250 @ F11.
Thankyou all. Its winter here in Iowa and there is not a whole lot to shoot outside these days very gray, no sun. Have to shoot inside, original subjects getting harder to find. I really like the light these old flash bulbs put out!
