Does this lens autofocus?

No. Focus, zoom and aperture are all manual, so you focus by hand and set exposure yourself.

Will it fit my camera?

It uses a T mount, so it fits most DSLR and mirrorless bodies with the matching T-mount adapter for your system.

Is it good for handheld wildlife shots?

Rarely. At 800mm and f/8.3 you need fast shutter speeds in bright light, and without stabilization a tripod or monopod is close to essential.

What is the aperture range?

It is a fixed f/8.3 lens. There is no wider aperture to gather more light, so it performs best outdoors in daylight.

What comes in the box?

The lens and its T mount. A camera-specific adapter is usually sold separately, so check that you have the right one.

Is it sharp at 800mm?

Owners report it is soft at the long end wide open and improves when stopped down, so expect to work within its limits.

Our take on the COMMANDER OPTICS 420-800mm f/8.3 Manual Telephoto Zoom Lens

The Commander Optics 420-800mm f/8.3 is a fully manual super-telephoto zoom with a T mount, so it fits almost any camera body with the right adapter. It offers a very long reach for wildlife, birds and distant subjects at a low cost compared with autofocus telephoto zooms. The trade-offs are real: a fixed f/8.3 aperture, no autofocus, no image stabilization and a heavy all-metal barrel. It suits patient hobbyists on a tripod who accept manual focus and bright light, not action shooters or handheld users.
