Error page “Lens not attached”

How to use the manual lens?

The “Lens not attached” error is normal when using a manual lens. To resolve this, set the camera to Manual Mode (M) and the error will disappear.Once in M mode, the lens can be used normally.Note that the aperture value will not be displayed (it will show “F–“). The aperture can only change automatically by adjusting the focal length, for example: 420mm/F8.3 → 500mm/F10 → 600mm/F12 → 700mm/F14 → 800mm/F16.

Why do I get the error page “Lens not attached” after installing our lenses?

Since there are no electronic contacts to recognize the lens, you cannot press the shutter button to take a picture and the “Lens not attached” error page appears. After switching to M, the error page disappears and it will work normally.

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.

Why is F– displayed and how can the aperture value be set?

As the manual lens has no electronic contacts to recognize the aperture value, “F–” 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)

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 1/125 to 1/250 sec.) to reduce the exposure and avoid overexposure.

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 1/250 to 1/125 sec.) to allow more light onto the sensor.

【Note: Manual Focus/MF】Please note: This is a manual focus lens (no autofocus/no AF)”. MUST need to “Set to camera mode to M (Manual)” for use, otherwise it will show the “Lens not attached” error (it will not allow you to press to shutter when in error page”. More important, manual lens MUST need to manual turn the “focus ring” on the lens to achieve focus.
【Super Telephoto Lens】Manual focus telephoto lens, a focal length of 420-800mm and an aperture of F/8.3-16 (non-adjustable aperture value, f8.3 at 420mm and f16 at 800mm), filter size of 62mm, full frame, F mount, built with high-quality materials and robust construction, making them durable and long-lasting;
【Upgraded version】Upgraded into an F mount, which can be mounted on Nikon DSLR cameras without connecting the T adapter ring. For those who photograph wildlife or the moon as a hobby, this lens would be a great choice;
【F Mount Compatibility】Compatible with Nikon D-series DSLR cameras: D850 D810 D810A D800 D800E D780 D750 D700 D610 D600 D500 D300 D300S D200 | D7500 D7200 D7100 D7000 D5600 D5500 D5300 D5200 D5100 D5000 D3500 D3400 D3300 D3200 D3100 D3000 | D100 D90 D80 D70 D70S D60 D50 D40X D40 | D6 D5 D4S D4 D3S D3X D3 D2XS D2X D2H D1X D1H D1;
【NO electronic contacts and No Autofocus Motor】Manual lenses lack electronic contacts, so you need to use our lens in Mode M. In the meantime, you must set the ISO/Shutter speed in mode M, otherwise the photo will come out too Bright/Black. On manual lenses, the camera may display F– because it doesn’t have direct access to the aperture value.
