How much magnification?
Magnification at a reasonable shooting distance?
Minimum barrel distortion and at what shooting distances and magnifications?
Can one force it to stop down to minimum aperture?
When stopped down to minimum aperture does a flat target, perpendicular to camera, produce an image sharp corner to corner?
Can one manually focus and if so is it accurate?
Is there a way to take a shot at any moment without shaking camera ala cable shutter release or more likely a remote control?
Any flash capabilities up close?
