>>3543939>or a Canon DemiJust remember that this one is a half frame. Also check the Olympus Pen series if you're into half frames, they're some of the best designed and have sharp, interchangeable lenses.
The smallest bar none (excluding some exotic shit) is the the Minox 35 or their clones, the Balda 35. They come in different models with different capabilities, but they all have a 35mm f/2.8 lens and lightmeter for autoexposure.
Picrelated is from a Balda.
The camera is literally the size of a pack of cigarettes.
