Two photos, two lenses. First is O45 f1.8, second EZ at 14mm. Both 1/6th at f5.6, 1600 ISO, hand held. No photo from the EZ at f5.6 because it hunted. Crop is < 100% because I'm showing shooting conditions, not demonstrating image quality. Neither lens was able to focus on the wall to the right of B or on the 90 degree angle at B. Both could focus on the 90 degree angle at A, but the EZ focused at 14mm and not at 42mm. The 45 and EZ at both 14 and 42 could focus on the edge of the window screen above the handle. Ah Ha! It hunts. So what? The EZ is a moderate speed pocket sized lens. That it's able so shoot useable images in such low light probably exceeds most users needs for the lens. I don't have a different kit zoom to test for hunting. Is it safe to say the larger, heavier kit zooms don't hunt in these situations but when on a GM1 they don't fit in a back pocket? A larger lens not being pocket sized and the pocket sized EZ hunting are not bugs, they're features.
