In my early days of collecting, I was never a real huge fan of the smaller subminiature cameras, mainly since most of them were the lesser quality cameras, or as I called them, "carnival camera" like the Hit camera. Then there was the other end. The 007 spy style camera was coming from Minox. As I grew in my camera maturity, coming across cameras like the Minolta or Yashica 16mm camera gave me an appreciation of some of these cameras' quality and quality.
My Round Petal camera
For this week's camera blog post, I wanted to go back to one of the subminiature cameras I have in my collection. The Petal camera has always intrigued me since it's the smallest of the small non-medical cameras made according to Guinness World Records. As far as cameras go, this one is tiny and just a little larger than a quarter in the US or a 2 Euro coin. The St. Peter Optical Company made the Petal camera, whose Japanese name was Sei-Petero Kōgaku, in 1948. According to some, I've seen some references where it stated its introduction in 1947. The first US advertising of the camera was in U. S. Camera in February 1949, which you can see here.
The Camera:
The Petal camera comes in two different styles, with an even rarer third version named the Evarax A. The two primary Petal camera are either a round-faced camera, which is what I own, or a second model with an octagonal shaped face. The Evarax A camera is an octagonal shaped face camera with a more elaborate etching on the faceplate. The Petal camera is only 1.25" across by 1.75" tall by 5/8" deep and weighs 2.2oz. The camera has a 12mm f5.6 lens, placed in the upper middle on the front of the camera. There are two shutter speeds, either "B" for time exposures or "I" for instant, which is 1/25th of a second, controlled by a wheel on the camera's front.

On the top of the camera is an optical viewfinder, and to the right of the viewfinder is the shutter trigger lever. Along the top of the optical viewfinder is a lever that can be mover over the trigger arm to lock it so you cannot take a photo when you don't want an accidental image taken. The shutter release lever pushes a plunger down into the camera, which trips the shutter. On the camera side is a knurled ring that you rotate to advance the film to the next exposures. To the side of the knurled ring, number 1 to 6 with indents stops the ring at the next photo.
Loading the Camera:
It took me some time to figure out how to get to the film chamber. After playing for about 15 minutes or so, I noticed that the back of the camera. The camera back can be unscrewed to get to the film cassette. Once the back is off, it exposes the film cassette. Once that's removed, you can see the shutter mechanism and the inside of the camera itself.

The film came in preloaded discs with 6-6mm images on each film cassette. The film cassette holds the film. To get to the film, the cassette needs to be unscrewed too. The original Petal film was a panchromatic film, which needed to be loaded in complete darkness. Many people used orthochromatic film like that can be loaded and unloaded under a red safelight, which doesn't affect the film. A film cutter allowed the Petal camera owners to cut 35mm film to use in the film cassettes.
Once the film is in the cassette and back into the camera, you thread the back onto the camera. You need to rotate the back portion of the camera one to two revolutions clockwise until the #1 is next to the exposure indicator. Doing this opens the film window on the film cassette and allows light to get to the film once the shutter is triggered.

After you took the six exposures, the exposure counter is at number six to unload the film. You need to turn the number counter clockwise two numbers to number 4, closing the film window and allowing the photographer to unscrew the back and take out the film cassette for processing.
Conclusion:
The Petal camera is a lot more sophisticated of a camera than I first thought when I purchased it many years ago. It's very well built and a prized camera to own for the "spy" photographers. Extremely small, very well made, and a beloved camera in my collection. The shutter on my camera is inoperable. It would be fun to cut some film and take it out for a spin.
If you have questions or comments about this camera or any others in my collection, I'd love to hear from you. Thank you for taking a few minutes from your day to read about this fun camera. Until next week, please be safe.
