I don't remember where I got this—either a friend gave it to me when she retired a lot of her old point-n-shoots, or it came in a lot I bought from a thrift shop that included something I had actually wanted. Either way, I have two of these things.
Kodak introduced four Trimlites in 1975, the models 18, 28, 38 and this 48.
Model 18: base model, 25mm ƒ/1 meniscus (single-element) lens, two shutter speeds, fixed-focus. Original price $24.
Model 28: 25mm ƒ/8 lens, variable shutter, auto exposure. Original price: $61.
Model 38: shutter has longer range, CdS metering. Zone-focus, two ranges (close and far). Original price: $110.
Model 48: 26mm ƒ/2.7 Ektar (Ektars are good), rangefinder focus. Original price: $146.
The magic of YouTube: Michael Raso and the Model 18 version. He should be on QVC.
