The Konica Pop (marketed as C35 EFJ in Japan) was a popular 35mm compact camera by Konica, made from 1982. It had fixed focus, one shutter speed, and manual film advance and rewind. There is an 'ISO selector' which is basically an aperture selector. It has CdS-based low-light warning LED and a retractable built-in flash powered by a pair of AA cells.

The camera was available in black finish as well as a palette of body colors, including yellow, red, blue, aqua, green, lime, pink, khaki and silver. After selling 1.5 million models, a major revision was made in 1985 and a new color scheme of metallic silver was added to the line.

These late editions did not have bear the "Hexanon" mark on the lens, possibly suggesting relaxed standard about optical quality, but the flash had an improved recharge time. A date model was released circa 1988.

Using the ISO selector[]

If you follow the ISO selector indications to match film speed, the camera will set aperture to target EV13 at all times. This mean that under various daylight conditions the film will potentially be overexposed by up to 2 stops or underexposed by up to 1 stop. This is, of course, not a problem for most color negative or black & white film.

For those who wish to use this camera with slide film or just want to nail correct exposure, here's what happens when you tweak the ISO selector depending on the speed of loaded film:

ISO100 ISO200 ISO400 ISO800
f/16 @400 EV15 EV14 EV13 EV12
f/11 @200 EV14 EV13 EV12 EV11
f/8 @100 @400 +flash EV13 EV12 EV11 EV10
f/5.6 @200 +flash EV12 EV11 EV10 EV9
f/4 @100 +flash EV11 EV10 EV9 EV8


  • EV15: Bright sunny day, hard shadows.
  • EV14: Hazy sunshine, small clouds, soft shadows.
  • EV13: Cloudy but bright, shadows barely visible.
  • EV12: Overcast or shade, no shadows.
  • EV11: Sunset.
  • EV10: Immediately after sunset.
  • EV9: Extremely bright neon signs at night.
