Q: Why can't I press the shutter after mounting the lens?

Please do Enable the "Release shutter w/o lens", and then you can press the shutter to take a picture.

Q: Why does my picture out of focus and very blurry?

Since our lenses are manual lenses, there are no electronic contacts for autofocus. Need to turn the focus ring (on the front of the lens) for manual focusing. If it is still blurry, use a tripod and time-lapse function to keep the image stable.

Q: Why is F00 displayed and how can the aperture value be set?

As the manual lens has no electronic contacts to recognize the aperture value, “F00” is displayed. The aperture value can only be adjusted automatically by changing the focal length. (420mm/F8.3 →500mm/F10→600mm/F12→700mm/F14→800mm/F16)

Q: What if the image turn out bright?

If the image is too bright, lower the ISO (e.g. from 200 to 100) to reduce the light sensitivity and increase the shutter speed (e.g. from 1/125s to 1/250s) to reduce the exposure and avoid overexposure.

Q: What if the image turn out dark?

If the image is too dark, increase the ISO (e.g. from 800 to 1600) to increase the sensitivity and decrease the shutter speed (e.g. from 1/250s to 1/125s) to allow more light onto the sensor.
